How Many Hours Can an HGV Driver Legally Drive? 2026 Rules Explained

Drivers' hours are the most tested topic in the HGV theory exam and the most enforced rules in professional driving. Getting them wrong costs marks in the test and, once you are working, can cost you your licence and your operator their O-licence. Here is the full picture, with the exact numbers you need to know.

The Daily Driving Limit

Under the EU and AETR rules that still govern UK professional driving, the daily driving limit is 9 hours. You can extend this to 10 hours, but no more than twice in any week.

Across a week you are capped at 56 hours of driving, and across any two consecutive weeks, 90 hours. That fortnightly cap is the one that catches people out: a heavy 56-hour week must be balanced by a lighter week either side of it.

Breaks: The 4.5-Hour Rule

After 4 hours 30 minutes of accumulated driving you must take a 45-minute break.

You can split the break into two parts: 15 minutes followed by 30 minutes — in that order. A 30-then-15 split does not count, and that exact trap appears in the theory test. During a break you must not drive or carry out any other work.

Daily and Weekly Rest

A regular daily rest is 11 continuous hours in every 24-hour period. It can be reduced to 9 hours up to three times between weekly rests, and there is a split option of 3 hours plus 9 hours, in that order.

A regular weekly rest is 45 continuous hours. It can be reduced to 24 hours, but the reduction must be compensated within three weeks.

Tachograph Rules That Go With Them

Everything above is evidenced by your tachograph. Driver cards must be downloaded at least every 28 days and vehicle units at least every 90 days, with records kept for 12 months. If your card is lost or stolen, report it to the DVLA within 7 days.

Why This Matters for Your Theory Test

Drivers' hours questions appear in almost every DVSA multiple-choice paper, usually testing the exact figures: 9 and 10 hours, 4.5 hours, 45 minutes, 56 and 90 hours, 11 and 9 hours. Learn the numbers as pairs and they stick.

The best way to make them permanent is testing yourself under real conditions.

Frequently Asked Questions

Can I drive 10 hours every day?

No. The 10-hour extended limit is allowed a maximum of twice per week. Every other day the limit is 9 hours.

Does queueing at a depot count as driving?

Time moving the vehicle counts as driving. Waiting time is usually recorded as other work or availability — but it is not a break unless you are genuinely free to rest.

What happens if I break the rules?

Fixed penalties, potential prosecution for serious or repeated offences, and consequences for your employer's operator licence. DVSA can check up to 28 days of records at the roadside.
