HGV Tachograph Rules UK: Downloads, Records, and Mistakes to Avoid

Why Do Tachograph Rules Matter?

Your tachograph record is the single most important piece of evidence in any driving hours investigation. Without clean records, you can't prove you've followed the rules — and that alone is an offence.

DVSA examiners check tachograph data at roadside stops, during operator audits, and as part of Earned Recognition inspections. Getting your records right isn't optional — it's the foundation of EU 561/2006 compliance.

Which Vehicles Need a Tachograph?

Any vehicle that falls under EU Regulation 561/2006 must have a tachograph fitted. In practice, that means:

• Goods vehicles over 3.5 tonnes used for commercial carriage
• Passenger vehicles carrying more than 9 people (including the driver) on commercial services

Digital tachographs are mandatory for vehicles first registered on or after 1 May 2006. Older vehicles may still use analogue tachographs with paper charts, though these are increasingly rare.

What Must Be Recorded?

The tachograph records four types of activity automatically:

The driving mode switches on automatically when the vehicle moves. But the other modes? You've got to set those yourself. If you're loading a trailer and leave the tacho on "rest", that's a false record — and DVSA won't be sympathetic.

What Are the Download Deadlines?

This is where operators often fall down. There are two separate download requirements:

Driver Card Downloads

Operator must download driver card data at least every 28 days. If the driver works for multiple operators, each operator is responsible for downloading the data covering their work.

Vehicle Unit Downloads

Operator must download data from the vehicle unit (the tachograph itself) at least every 90 days.

Miss these deadlines and DVSA can issue an infringement. It's one of the most common findings in operator audits because it's easy to let slide — especially with agency drivers who come and go.

What About the 28-Day Driver Record Requirement?

Drivers must be able to produce records covering the current day plus the previous 28 calendar days at any roadside check. That means carrying your driver card and having manual records for any days you weren't using a digital tacho.

If you drove for a different operator, used an analogue tachograph, or were off sick — you still need a record of what you were doing. Use an attestation form (sometimes called a "letter of activities") to cover those gaps.

When Do You Need Manual Entries?

Manual entries are required whenever the tachograph couldn't record your activity automatically. Common situations:

• Forgot to insert your card — you must add the missing data on the back of a printout or on a temporary sheet
• Card was in another vehicle — record the activity manually
• Out-of-scope driving — if you drove a vehicle not covered by EU rules (under 3.5t, for example)
• Rest days and holidays — these must be recorded, either via the tachograph or on attestation forms
• Tachograph malfunction — you must make manual records on the back of the printout roll and get the tacho repaired within 7 days (or by return to base if that's sooner)

Common Tachograph Mistakes DVSA Catches

1. Missing manual entries — gaps in your record with no explanation. DVSA treats unexplained gaps as potential infringements.
2. Wrong mode selected — recording "rest" when you're actually doing other work (loading, paperwork). This counts as a false record.
3. Late downloads — driver card not downloaded within 28 days or VU not downloaded within 90 days.
4. No attestation forms — days off, sick leave, or holiday not covered by any record.
5. Driving without a card — if your card is lost, stolen, or malfunctioning, you can drive for up to 15 days without it — but you must print out at the start and end of each day and add your name and card/licence number.
6. Not keeping records for 12 months — operators must retain all tachograph data for at least 12 months. Losing data isn't an excuse.

What Happens If Your Card Is Lost or Broken?

If your driver card is lost, stolen, damaged, or malfunctioning:

1. You can continue driving for a maximum of 15 calendar days (or longer if needed to return to base)
2. Print out the tachograph at the start and end of each day
3. Write your name and driver card or licence number on each printout
4. Apply for a replacement card within 7 calendar days

Don't just carry on without telling anyone. Report it to your operator immediately and apply for a replacement through DVLA.

How to Keep Your Records Clean

Most tachograph issues come down to poor habits, not deliberate rule-breaking. Here's what works:

• Set your mode correctly every time you stop driving — don't leave it on autopilot
• Carry attestation forms for any days you're not driving
• Check your download schedule — set calendar reminders for the 28-day and 90-day deadlines
• Use analysis software — tools like ShiftOwt help track driver availability and compliance records so nothing falls through the cracks
