USING A DIGITAL TACHOGRAPH.

THE COMPLETE PRACTICAL GUIDE.

From inserting your card to manual entries, modes, printouts, Smart 1, Smart 2 and finishing your shift.

For many newly qualified HGV drivers, the tachograph is one of the most intimidating pieces of equipment in the cab.

You may have learned about drivers' hours for your theory test. You know that you need a driver card. You may recognise the bed symbol and the crossed hammers.

Then somebody hands you the keys to a lorry and suddenly you are looking at a small screen full of symbols, menus, numbers and buttons and wondering:

What exactly am I supposed to press?

This guide starts at the beginning.

1. WHAT DOES A TACHOGRAPH ACTUALLY DO?

A digital tachograph is the recording system fitted to most modern commercial vehicles that fall within EU drivers' hours rules.

It records information including:

• your driving;

• other work;

• breaks and rest;

• periods of availability;

• distance travelled;

• vehicle movement;

• speed information;

• driver-card activity;

• certain locations and events;

• and, on newer Smart tachographs, additional location and operational information.

Information is stored in two main places:

Your driver card

and

The Vehicle Unit (VU) fitted to the vehicle.

Think of your driver card as your personal driving record and the VU as the vehicle's record.

2. YOUR DRIVER CARD

Your driver card belongs to you, not your employer and not the lorry.

It is personal to you.

You must not:

• use somebody else's card;

• allow somebody else to use yours;

• deliberately drive another driver's card;

• have multiple valid driver cards in order to conceal activity.

  
  

Your card travels with you when you change employers or vehicles.

Treat it carefully. Keep it clean, don't bend it and don't leave it somewhere another person could use it.

3. THE TWO CARD SLOTS

A digital tachograph normally has two card slots.

SLOT 1 – DRIVER

If you are driving the vehicle, your card belongs in:

Slot 1.

SLOT 2 – SECOND DRIVER

Where the vehicle is genuinely multi-manned, the second driver's card goes into:

Slot 2.

When drivers swap, their cards/positions must correctly reflect who is actually driving.

The tachograph must know who is at the wheel.

4. BEFORE YOU MOVE THE LORRY

Do not start driving and then think:

“I'll put my card in down the road.”

Insert your card when you take over the vehicle and before driving it.

Remember that your working day may already have started before the vehicle moves.

For example:

05:45 – arrive at work

05:50 – start walkaround check

06:05 – finish check

06:10 – insert card

06:15 – drive

Your work did not begin at 06:15.

The walkaround check was other work.

That period needs to be accounted for.

This is exactly what manual entries are for.

5. INSERTING YOUR DRIVER CARD

Insert the card into Slot 1.

On most units, the chip faces upwards, although always follow the design of the unit/card slot in front of you.

The tachograph reads your card.

Depending on the make and model, you may see:

• your name;

• the date/time your card was last withdrawn;

• a question asking whether you want to make a manual entry;

• beginning-country information;

• other prompts.

  
  

Do not automatically hammer OK through every screen.

Read what the machine is asking.

6. THE FOUR ACTIVITY SYMBOLS YOU MUST KNOW

These are the heart of tachograph use.

🚚 STEERING-WHEEL SYMBOL – DRIVING

This means:

DRIVING

You normally don't manually select driving.

When the vehicle begins moving, the tachograph automatically records driving.

⚒ CROSSED HAMMERS – OTHER WORK

This means:

OTHER WORK

Use this whenever you are working but not driving.

Examples include:

• walkaround checks;

• loading;

• unloading;

• assisting with loading/unloading;

• washing the lorry;

• paperwork connected with your job;

• refuelling;

• securing a load;

• maintenance work;

• coupling or uncoupling;

• work for another employer;

• other duties.

  
  

One of the biggest lessons for a new driver is:

Not driving does NOT automatically mean break.

If you are working, select other work.

□/DIAGONAL-LINE SYMBOL – PERIOD OF AVAILABILITY

This is:

POA – PERIOD OF AVAILABILITY

POA is not simply:

“I'm waiting.”

Broadly, it is a qualifying waiting period where you are not required to remain at your workstation, you remain available to resume work, and the reasonably foreseeable duration of the wait is known in advance.

Examples can include certain known waiting periods at loading/unloading points or accompanying a vehicle on a ferry.

Don't use POA simply because you don't know what else to press.

🛏 BED SYMBOL – BREAK/REST

The bed means:

BREAK OR REST

Use it when you are genuinely taking a qualifying break or rest and are free from work.

It can represent:

• a driving break;

• a WTD break;

• daily rest;

• weekly rest;

• other qualifying rest.

  
  

If you're on the bed symbol but you're actually loading cattle, washing the trailer or doing paperwork, the tachograph record does not accurately represent what you were doing.

7. THE MOST IMPORTANT MODE-SWITCH HABIT

Whenever you stop driving, ask:

“What am I doing NOW?”

If you're working:

⚒ OTHER WORK

If you're genuinely waiting and the conditions for POA are met:

POA

If you're genuinely taking a break:

🛏 BREAK/REST

Driving will normally be selected automatically when the vehicle moves.

8. BE CAREFUL WHAT HAPPENS WHEN THE VEHICLE STOPS

Different tachograph configurations may behave differently when the vehicle stops.

A unit may revert to a preset activity such as other work when driving ends.

Never assume the machine has selected the activity you actually want.

Look at the display.

If you park for a 45-minute break but leave the unit recording other work, you've just recorded 45 minutes of work instead of the break you intended to take.

The tachograph cannot know whether you've stopped to unload or stopped for lunch.

You have to tell it.

9. WHAT IS A MANUAL ENTRY?

This is one of the most important tachograph skills you can learn.

A manual entry tells your driver card what you were doing during a period when your card was not recording your activity in a tachograph.

When you insert your card, the machine knows:

Card removed: yesterday 17:30

and:

Card inserted: today 06:10

But it does not automatically know what happened between those two times.

You tell it through a manual entry.

10. WHY DO MANUAL ENTRIES MATTER?

Your tachograph record should provide a continuous and accurate record of your relevant activity.

Imagine:

Yesterday:

17:30 – card removed and finished work.

Today:

05:45 – arrived at work.

05:45–06:10 – walkaround check and paperwork.

06:10 – inserted card.

Between 17:30 and 05:45 you were resting.

Between 05:45 and 06:10 you were working.

Your manual entry should therefore reflect:

17:30 → 05:45 = REST

05:45 → 06:10 = OTHER WORK

Now your record makes sense.

11. HOW TO MAKE A MANUAL ENTRY

The precise buttons and wording differ between tachograph manufacturers and generations, but the principle is the same.

When you insert your card, the unit will normally ask whether you want to make a manual entry.

Select:

YES

You then work through the period since your card was last removed.

Enter the correct activity for each period:

🛏 Rest

⚒ Other work

POA where genuinely applicable

and confirm the appropriate times.

Then confirm your entry.

Read the times carefully before confirming.

Don't rush this.

12. A VERY SIMPLE MANUAL ENTRY

Yesterday:

18:00 – finished work and removed card.

Today:

06:00 – arrive and immediately insert card.

Your missing period is simply:

18:00 → 06:00 = REST.

Easy.

13. A MORE REALISTIC MANUAL ENTRY

Yesterday:

18:00 – card removed.

Today:

05:30 – arrive at yard.

05:30–05:45 – walkaround check.

05:45 – card inserted.

Your manual entry should show:

18:00 → 05:30 = REST

05:30 → 05:45 = OTHER WORK.

That 15-minute vehicle check is work.

(The simplest way to make sure your walkaround check and other start-of-shift duties are recorded correctly is to put your driver card in before you begin them.

For example, if you arrive at your lorry at 06:00, switch on the ignition and insert your driver card into Slot 1. Complete any manual entries required to account for the period since you last removed your card, enter your start country, and allow the tachograph to finish reading your card.

Once you are logged on, make sure the tachograph is set to Other Work (crossed hammers).

You can then carry out your daily walkaround check, complete your paperwork and perform any other work required before departure. All of that time is being recorded correctly as Other Work while you are doing it.

If you finish your checks and paperwork at 06:15 and are ready to leave, simply begin driving. As soon as the vehicle moves, the tachograph will automatically change from Other Work to Driving.

So your morning record is nice and straightforward:

06:00 — Card inserted → Other Work

06:00–06:15 — Walkaround check and paperwork → Other Work

06:15 — Vehicle moves → Driving automatically begins

This is much simpler than carrying out your walkaround first and then having to manually enter that period of Other Work afterwards.

GOOD HABIT: Put your card in and get your tachograph recording correctly before you start your walkaround and other vehicle-related work.)

14. WHAT IF YOU DID OTHER WORK BEFORE COMING TO THE LORRY?

Record it.

Suppose you:

05:00–05:30 – worked in the office.

05:30–05:45 – walkaround.

05:45 – inserted card.

Your manual entry should account for that working period.

The tachograph doesn't only care about work performed while sitting in the driver's seat.

15. WHAT IF YOU WORKED FOR ANOTHER EMPLOYER?

That can still be other work.

Relevant work for another employer does not magically disappear because it wasn't HGV driving.

Your record must accurately reflect your activities.

16. COUNTRY OF START

At the beginning of your daily working period, record the country where your working period begins.

For Ireland:

IRL

Do this even if you never leave Ireland.

It is not merely an international-driving requirement.

17. COUNTRY OF END

At the end of your daily working period, record the country where you finish.

Again, in Ireland:

IRL

This is one of the easiest things for drivers to forget.

Make it part of your end-of-shift routine:

End country → eject card → done.

18. DO NOT CONFUSE CARD REMOVAL WITH END OF WORK

Removing your card does not automatically mean:

“I have finished working.”

If you remove your card and then spend 20 minutes doing paperwork, washing the vehicle or carrying out another work activity, that is still work.

It must be recorded appropriately.

Think about when your work actually ends, not merely when you want to take the card out.

19. WHAT DOES THE NORMAL DISPLAY SHOW?

Exact displays differ between VDO, Stoneridge and other approved units, and between generations.

Typically, you will see information relating to things such as:

• current activity;

• driver 1;

• driver 2;

• current time;

• driving/activity information;

• card status;

• warnings or messages.

• 
  

More advanced units can also display counters or summaries relating to driving and rest.

Learn the unit in the vehicle you actually drive.

Do not assume every tachograph menu looks identical.

20. THE BUTTONS

Again, exact layouts vary, but digital tachographs generally give you controls to:

• move through menus;

• move up/down through options;

• confirm an entry;

• go back;

• change activity;

• eject driver cards;

• access print functions.

  
  

On many units:

OK confirms.

Arrow buttons move through menus/options.

Dedicated 1 and 2 controls relate to driver slots/activities.

Long presses and short presses may perform different functions.

If you're unfamiliar with a particular unit, spend a few minutes learning its controls while safely parked.

21. CHECK YOUR ACTIVITY AFTER STOPPING

This habit can save you a lot of trouble.

Every time you stop:

look at the tachograph.

If you're going on break, confirm it is actually displaying the break/rest symbol.

If you're unloading, confirm you're recording other work.

If you're legitimately on POA, make sure that's what is selected.

Don't discover at the end of the day that the 45-minute break you thought you took was recorded as 45 minutes of other work.

22. PRINT OUTS – WHAT ARE THEY?

The tachograph contains a small thermal printer.

It can produce paper records containing tachograph information.

Printouts can be used for several purposes, including:

• examining your activity;

• providing a manual record;

• explaining certain errors;

• recording exceptional circumstances;

• dealing with a malfunctioning/lost/damaged driver card;

• correcting a record;

• providing information during a roadside enforcement check.

  
  

Keep spare approved printer paper in the vehicle.

A printer isn't much use if there's no roll in it.

23. HOW DO YOU READ A PRINTOUT?

A printout can initially look like hieroglyphics.

Don't panic.

Read it systematically.

It normally contains sections identifying things such as:

Driver/card details

Vehicle/VU details

Date

Activities

Times

Distances/odometer information

Events/faults

Summary information

The same activity symbols appear:

Driving

⚒ Other work

POA

🛏 Break/rest

Follow the timeline.

Ask:

What activity was recorded?

When did it start?

When did it finish?

How long did it last?

Once you stop seeing the printout as a wall of symbols and start reading it as a timeline, it becomes much easier.

24. WHAT IF YOU MAKE A MISTAKE?

Do not try to conceal it.

And don't panic.

If you select the wrong mode and the incorrect activity has already been recorded, the tachograph generally does not allow you simply to rewrite historical data on the card.

Make an appropriate printout as soon as possible.

On the printout, clearly record:

• the correction;

• what actually happened;

• the relevant activity/time;

• the reason if appropriate;

• your name/signature as required.

  
  

Keep the printout with your records and provide it to your operator in accordance with company procedure.

A genuine error that has been properly identified and corrected is very different from deliberately creating a false record.

25. MANUAL WRITING ON PRINTER PAPER

Printer roll isn't only for machine-generated information.

Where regulations require a manual record or explanation, the reverse of a suitable piece of print roll can be used.

Write clearly and legibly.

Include sufficient information to explain:

• who you are;

• the relevant date/time;

• the activity/correction;

• why the manual record was necessary;

• and your signature where required.

  
  

26. WHAT IF YOU FORGET TO CHANGE MODE?

Example:

You stop at 12:00 for a 45-minute break.

You forget to select bed.

The tachograph records:

12:00–12:45 = OTHER WORK.

You cannot simply pretend the machine recorded break.

Your electronic record says other work.

Make the appropriate correction/manual record using a printout and follow your company's procedure.

And learn from it.

27. WHAT IF YOU FORGET YOUR DRIVER CARD?

This is very different from your card being lost, stolen, damaged or malfunctioning.

Simply forgetting your card at home is not a general exemption allowing you to drive without it.

If you are required to use a driver card, make sure you have it with you.

Put it somewhere that becomes part of your work routine.

28. LOST, STOLEN, DAMAGED OR MALFUNCTIONING CARD

There are specific legal procedures where a card is genuinely:

• lost;

• stolen;

• damaged;

• malfunctioning.

  
  

You may be permitted to continue driving without the card for a limited period where the legal conditions are met, but additional records are required.

At the beginning of the journey, make a printout of the vehicle information and add the required identifying information and signature.

At the end of the journey, make another printout covering the relevant activity and add the required information.

Apply for a replacement card within the required timeframe.

Do not treat the lost-card procedure as an alternative to carrying your card.

29. WHAT IS “OUT”?

You may see:

OUT

or:

OUT OF SCOPE

This relates to vehicle use outside the scope of the relevant EU drivers' hours/tachograph rules.

It does not mean:

“I'm driving but don't want this counted.”

Whether a journey is legally out of scope depends on the vehicle, operation and applicable exemption/derogation.

Do not select OUT simply because:

• you're driving around the yard;

• you're going a short distance;

• you're driving empty;

• you don't have a load;

• you are going home;

• somebody told you “it doesn't count”.

• 
  

Establish that the activity is genuinely out of scope.

30. FERRY/TRAIN MODE

Modern tachographs have a specific:

FERRY/TRAIN function.

This is used where the relevant ferry/train rest provisions are being applied.

It is not simply something you select because your lorry happens to be on a ferry.

The drivers' hours legislation contains specific conditions governing when a daily or qualifying weekly rest can be interrupted for embarking/disembarking.

If you are relying on the ferry/train provision, use the tachograph's ferry/train function correctly and understand the underlying rest rules.

31. BORDER CROSSINGS

This is particularly important for international drivers.

With older digital tachographs and Smart Tachograph Version 1, drivers have had to manually record the country entered after crossing an EU Member State border at the required first suitable stopping place.

Smart Tachograph Version 2 automatically records border crossings.

That is one of the major practical improvements of Smart 2.

However, you must still correctly record the country where your daily working period starts and finishes as required.

Don't assume “smart” means the machine now does absolutely everything for you.

32. WHAT IS A SMART TACHOGRAPH?

A Smart tachograph is a newer generation of digital tachograph incorporating additional technology such as satellite positioning and remote communication capabilities.

There are two generations you will commonly hear discussed:

Smart 1

and

Smart 2.

33. SMART 1

Smart Tachograph Version 1 was introduced for newly registered vehicles from 2019.

Compared with earlier digital tachographs, it introduced features including:

• GNSS satellite positioning;

• additional location recording;

• remote communication capabilities for enforcement;

• improved security and anti-tampering measures.

  
  

It was a significant development from the earlier digital tachograph.

But Smart 1 does not automatically record EU border crossings in the same way Smart 2 does.

34. SMART 2

Smart Tachograph Version 2 is the newer generation.

Among its additional functions are:

• automatic recording of border crossings;

• enhanced position recording;

• ability to record loading/unloading operations and their location;

• improved anti-tampering capabilities;

• enhanced remote communication functionality;

• additional data intended to assist enforcement of EU transport rules.

  
  

For an international driver, automatic border recording is one of the most noticeable practical differences.

35. LOADING AND UNLOADING ON SMART 2

Smart 2 includes functionality allowing a driver to record:

LOAD

UNLOAD

or:

simultaneous load/unload.

The tachograph then associates the operation with location information.

This is separate from your activity mode.

For example, if you're physically loading the vehicle, your activity would normally be:

⚒ OTHER WORK

while the Smart 2 load function records the loading event/location.

The European Commission strongly encourages drivers to use this functionality so that a complete record exists.

36. SMART DOES NOT MEAN AUTOMATIC EVERYTHING

This is worth repeating.

Smart 2 is clever.

It is not psychic.

It can automatically record things such as:

• vehicle movement;

• certain location data;

• border crossings.

  
  

But it cannot reliably decide whether you are:

• having lunch;

• unloading;

• waiting;

• doing paperwork;

• on POA;

• taking daily rest.

  
  

You still need to use the correct activity mode.

37. REMOTE ENFORCEMENT DOES NOT MEAN “REMOTE FINE”

Smart tachographs can transmit certain information to authorised enforcement equipment for the purpose of helping officers identify vehicles that may warrant further inspection.

This does not mean every detail of your driver card is constantly being broadcast to every enforcement officer.

The remote system is principally a targeting tool.

The vehicle may then be stopped for a proper inspection where appropriate.

38. DOUBLE MANNING

If two drivers are operating as a genuine multi-manned crew:

Driver currently driving → Slot 1

Second driver → Slot 2

When the drivers change over, ensure the tachograph accurately reflects the new positions/activities.

Do not simply swap seats and forget about the cards.

While the vehicle is moving, time spent by the second driver sitting beside the driver will normally be recorded appropriately as availability, subject to the applicable rules.

39. CHANGING VEHICLES DURING THE DAY

Your card goes with you.

If you finish in Lorry A and move into Lorry B:

• safely finish with the first vehicle;

• ensure your activities are correctly recorded;

• remove your card;

• insert it into the second vehicle;

• respond correctly to any prompts/manual-entry requirements;

• complete a walkaround check

• continue recording your working day.

  
  

Changing lorries does not start a new drivers' hours day.

Your card carries your activity with you.

40. WHAT IF SOME OF YOUR DAY WAS RECORDED ON AN ANALOGUE TACHOGRAPH?

Do not duplicate activities that are already properly recorded on an analogue chart by entering them again onto your digital card.

Keep the relevant analogue records as required.

Your records across the different systems collectively demonstrate your activity.

41. LEAVING YOUR CARD IN OVERNIGHT

Do not assume leaving your card inserted automatically deals with everything.

You are still responsible for correct activity and country records.

In particular, start/end country requirements still apply even where the card remains inserted.

Many drivers prefer to remove their card at the end of the working period as part of a clear end-of-shift routine.

Follow legal requirements and your company's procedure.

42. START-OF-SHIFT ROUTINE

A good routine might be:

1. Arrive at work.

2. Begin recording/remember the time your work actually starts.

3. Carry out your walkaround check.

4. Enter the cab.

5. Insert your driver card into Slot 1.

6. Read the display.

7. Make the required manual entries.

8. Account for rest and any other work since the card was removed.

9. Enter/confirm your start country.

10. Confirm the entries carefully.

11. Check the tachograph shows the correct current activity.

12. Only then begin driving.

Make that routine automatic.

43. END-OF-SHIFT ROUTINE

At the end of your working period:

1. Finish your driving.

2. Complete any remaining other work.

3. Ensure all activities are properly recorded.

4. Enter your end country.

5. Check whether anything needs correcting or explaining.

6. Make a printout if necessary.

7. Eject your driver card when appropriate.

8. Take your card with you.

Do not finish a 12-hour day and suddenly rush the last 30 seconds.

Your tachograph record matters.

44. THE TACHOGRAPH CLOCK

Digital tachographs use UTC internally for their formal records, although modern units may also display local time for driver convenience.

Don't confuse the displayed local time with how the underlying data is stored.

This becomes particularly noticeable when clocks change between summer and winter time or when travelling between time zones.

45. WARNINGS

The tachograph can generate warnings relating to things such as:

• approaching driving limits;

• card issues;

• events/faults;

• power interruption;

• motion conflicts;

• overspeed;

• time overlap;

• card insertion/withdrawal events.

  
  

Do not blindly press OK simply to make the noise or message disappear.

Read the warning.

Work out what it means.

Then respond appropriately.

46. “TIME OVERLAP”

You may occasionally encounter a time-overlap warning, particularly when manual entries or card records conflict chronologically.

Stop and read what the unit is telling you.

Don't repeatedly confirm screens you don't understand.

If necessary, seek assistance before creating an inaccurate record.

47. POWER INTERRUPTION

A power interruption can be recorded as an event.

If the tachograph suddenly reports one and you have not knowingly disconnected power or had vehicle work carried out, report it.

Tachograph security events and unexplained power interruptions can attract attention during analysis or enforcement.

48. MOTION CONFLICT

A motion conflict generally indicates that the tachograph has received inconsistent information concerning vehicle movement from its different sources/sensors.

Again:

don't just ignore recurring faults.

Report them through the operator's defect/compliance procedure.

49. TACHOGRAPH MALFUNCTION

If the tachograph itself becomes faulty, there are legal procedures for recording your activity manually and having the equipment repaired.

Do not simply continue for days assuming:

“The tacho is broken so the rules don't apply.”

The drivers' hours rules still apply.

Your obligation to maintain records still applies.

Use the required manual records/printouts and notify the operator immediately.

50. DOWNLOADS

Your driver card needs to be downloaded regularly by the operator.

Under the Irish rules, the maximum normal download intervals are:

Driver card – at least every 28 days

Vehicle Unit – at least every 90 days.

An operator may choose to download more frequently.

For example, a company might use a 21-day driver-card schedule and a 77-day VU schedule.

That's perfectly sensible – company policy can be more frequent than the legal maximum interval.

Downloading the card does not delete your responsibility or magically “clear” infringements.

The data is analysed and retained.

51. WHAT DOES TACHOGRAPH ANALYSIS SHOW?

Analysis software can identify things such as:

• excessive driving;

• insufficient breaks;

• insufficient daily rest;

• weekly-rest problems;

• country-code issues;

• card-related events;

• missing activity;

• Working Time issues depending on the system/data;

• possible anomalies;

• recurring patterns.

  
  

This is why accurate mode selection and manual entries matter.

Bad data creates bad records.

52. ENFORCEMENT – HOW FAR BACK CAN THEY LOOK?

This changed and is important.

Since 31 December 2024, at roadside a driver must be able to produce relevant records covering:

the current day and the previous 56 days.

That includes required manual records and printouts, together with the driver card and applicable analogue records.

You will still find older guides saying:

28 days.

That figure is now outdated for this roadside record-production requirement.

53. KEEP YOUR PRINTOUTS

If you make a printout because:

• you corrected an activity;

• explained an exceptional event;

• drove under the lost/damaged card procedure;

• dealt with a tachograph malfunction;

• or created another required manual record,

don't throw it on the dashboard and lose it three days later.

Keep required records safely and make sure your operator receives copies where appropriate.

54. COMMON NEW-DRIVER MISTAKES

Mistake 1:

Inserting the card only when you're ready to drive.

Problem: You may fail to record earlier other work.

Mistake 2:

Pressing NO to manual entry automatically.

Problem: Missing activity remains unaccounted for.

Mistake 3:

Putting everything on break when parked.

Problem: Loading, unloading and other work aren't breaks.

Mistake 4:

Using POA whenever you're waiting.

Problem: Not every waiting period qualifies as POA.

Mistake 5:

Forgetting start/end country.

Problem: These are required records.

Mistake 6:

Assuming the tachograph automatically selects break.

Problem: It doesn't know why you've stopped.

Mistake 7:

Moving the lorry before inserting your card.

Problem: Uncarded driving is recorded by the VU.

Mistake 8:

Using OUT without understanding why.

Problem: OUT is not a button for making driving disappear.

Mistake 9:

Ignoring warnings.

Problem: The warning may indicate a compliance issue, card problem or equipment fault.

Mistake 10:

Assuming Smart 2 does everything.

Problem: The driver still has to record activities correctly.

55. THE GOLDEN RULE OF MANUAL ENTRIES

When your card wasn't in a tachograph, ask:

“What was I actually doing during that time?”

Then record exactly that.

Don't start by asking:

“What entry will keep me legal?”

Start with:

“What actually happened?”

Your record should reflect reality.

56. THE GOLDEN RULE OF MODES

Whenever the vehicle stops, ask:

“Am I working, available, or resting?”

Working:

⚒

Qualifying POA:

POA

Break/rest:

🛏

Driving:

Automatically recorded when the vehicle moves.

That simple question prevents an enormous number of mistakes.

57. THE GOLDEN RULE OF TACHOGRAPHS

A tachograph is a recording device.

It is not your Transport Manager.

It is not your compliance officer.

And it is not a substitute for understanding drivers' hours and Working Time.

A countdown on a screen can be useful.

But you still need to understand:

• how much you have driven;

• how much you have worked;

• what break you need;

• what daily rest you need;

• what weekly rest you need;

• whether you've used reduced rests;

• whether you've extended daily driving;

• and what your Working Time position is.

  
  

58. BEFORE YOU PRESS OK…

This might be the most useful practical advice in this entire guide:

READ THE SCREEN.

New drivers are often frightened of tachographs because they look complicated.

Then they develop the worst possible habit:

OK → OK → OK → OK → OK

just to get through the menus.

Slow down.

Look at the symbol.

Look at the date.

Look at the time.

Read the question.

Ask yourself what the machine is requesting.

Then answer it.

You are not going to break the tachograph by taking ten seconds to read it.

59. IF YOU DON'T UNDERSTAND SOMETHING – ASK

There is no shame whatsoever in being newly qualified and not knowing how a particular tachograph works.

There is a problem if an employer puts a new driver into an unfamiliar vehicle with no explanation and simply expects them to figure everything out while trying to work.

Ask another experienced driver.

Ask your Transport Manager.

Ask whoever is responsible for compliance.

Look at the manufacturer's instructions.

Get somebody to physically show you.

A five-minute explanation in the yard can prevent weeks of incorrect records.

60. YOUR 30-SECOND TACHOGRAPH CHECKLIST

STARTING WORK

Card → Manual entry → Start country → Correct mode → Drive

WHEN YOU STOP

Look at the screen → Select what you're actually doing

DURING THE DAY

Watch driving time + working time → Read warnings → Record activities accurately

CHANGING VEHICLES

Finish correctly → Card out → Card into new VU → Read prompts → Continue

FINISHING

Finish all work → End country → Correct anything necessary → Card out

And every time you're unsure:

READ THE SCREEN BEFORE YOU PRESS THE BUTTON.

THE FINAL POINT

Your tachograph is not there to catch you out.

It is there to create a record of what you actually did.

Once you understand that, using it becomes much less intimidating.

You don't need to memorise every menu on every tachograph ever manufactured.

You need to understand:

what activity you are doing,

how that activity should be recorded,

what information the machine is asking you for,

and:

whether the record on your card accurately represents your working day.

Get those principles right and the buttons become the easy part.
