Why Driver Hours Rules Matter
Driver hours legislation exists to prevent fatigue-related accidents. HGV drivers are legally required to limit their driving time, take mandatory breaks, and rest for specified periods. Breaching these rules can result in fixed penalty notices, prohibition orders, loss of your Driver CPC, and in serious cases, prosecution. Employers and operators face equally severe penalties, including loss of their operator licence.
There are two sets of rules that apply to HGV drivers in the UK: EU rules (which still apply in Great Britain post-Brexit for most international and domestic journeys) and GB domestic rules (which apply to certain exempt vehicles and journeys). Most HGV drivers on UK roads are subject to EU rules.
EU Driver Hours Rules at a Glance
| Rule | Limit |
|---|---|
| Daily driving limit | 9 hours (can be extended to 10 hours twice per week) |
| Weekly driving limit | 56 hours |
| Fortnightly driving limit | 90 hours across any two consecutive weeks |
| Break after 4.5 hours driving | 45 minutes (or 15 min + 30 min in that order) |
| Daily rest (standard) | 11 consecutive hours |
| Daily rest (reduced) | 9 consecutive hours (maximum 3 times between weekly rests) |
| Weekly rest (regular) | 45 consecutive hours |

The 4.5-Hour Driving Rule Explained
After a maximum of 4 hours and 30 minutes of driving, you must take a break of at least 45 minutes. This break can be split into two parts: a first break of at least 15 minutes followed by a second break of at least 30 minutes. The breaks must be taken in this order — you cannot take the 30-minute break first.
During a break, you must not drive or carry out any other work. Waiting time, loading, and administrative tasks all count as "other work" and do not qualify as a break.
Daily Rest Requirements
Between any two consecutive working days, you must take a daily rest period. The standard daily rest is 11 consecutive hours. This can be reduced to 9 consecutive hours up to three times between any two weekly rest periods — but the reduction must be compensated before the end of the following week.
Daily rest can be taken in a vehicle, provided it has a suitable sleeping facility and is stationary. Split daily rest is also permitted: you can split your daily rest into two periods — the first of at least 3 hours and the second of at least 9 hours — giving a total of at least 12 hours.
Weekly Rest Requirements
A regular weekly rest is 45 consecutive hours. A reduced weekly rest is 24 consecutive hours. You must take a regular weekly rest at least once every two weeks. Any reduction in weekly rest must be compensated in full before the end of the third week following the week in question.
Since 2022, drivers are no longer permitted to take their regular weekly rest in their vehicle cab. Regular weekly rest (45 hours) must be taken in suitable accommodation — a hotel, B&B, or at home.
GB Domestic Rules
GB domestic rules apply to vehicles exempt from EU rules, including certain agricultural vehicles, vehicles used by the armed forces, and vehicles not exceeding 3.5 tonnes. Under GB domestic rules:
- Maximum daily driving: 10 hours
- Maximum daily duty: 11 hours (or 12.5 hours if driving does not exceed 4 hours)
- Break after 5.5 hours: 30 minutes (or three 10-minute breaks spread over the period)
- Daily rest: 10 consecutive hours (reducible to 8.5 hours up to three times per week)
Tachograph Requirements
All vehicles subject to EU rules must be fitted with a tachograph — a device that automatically records driving time, speed, and distance. Since 2006, all new vehicles must be fitted with a digital tachograph. Drivers must use a personal driver card (issued by the DVLA) to record their activities.
You are required to keep your tachograph records for at least 28 days and must be able to produce them on request at the roadside or during an operator inspection. For a full guide to tachograph rules, read our Tachograph Rules Explained post.
Common Mistakes and How to Avoid Them
| Mistake | Consequence | How to Avoid |
|---|---|---|
| Forgetting to insert driver card | Unrecorded driving — automatic offence | Insert card before starting engine every time |
| Taking break too late | Exceeding 4.5-hour driving limit | Set a timer or use a driving time app |
| Counting waiting time as a break | Insufficient break — hours violation | Only count time when doing nothing work-related |
| Forgetting to compensate reduced weekly rest | Weekly rest violation | Plan compensation in advance with your employer |
| Taking regular weekly rest in the cab | Regulatory offence since 2022 | Book accommodation for weekly rest periods |
Penalties for Breaching Driver Hours Rules
DVSA enforcement officers can stop vehicles at the roadside and check tachograph records. Fixed penalty notices start at £100 for minor offences and can reach £300 per offence. Serious or repeated breaches can result in a court summons, an unlimited fine, and disqualification from driving. Drivers who accumulate serious offences risk losing their Driver CPC qualification, which would end their professional driving career.
Frequently Asked Questions
Do driver hours rules apply on weekends?
Yes. EU driver hours rules apply every day of the week, including weekends and bank holidays. There is no exemption for weekend driving.
What counts as "driving time" for the 4.5-hour rule?
Any time the vehicle is moving under your control counts as driving time. Time spent stationary in traffic also counts as driving time if the engine is running and you are in control of the vehicle.
Can I drive more than 9 hours in a day?
Yes — you can extend your daily driving to 10 hours, but only twice in any one week. You cannot extend beyond 10 hours under any circumstances.
Do I need to record breaks and rest periods on my tachograph?
Yes. Your tachograph must record all activities: driving (D), other work (W), availability (A), and rest/break (B). Failure to record non-driving periods correctly is itself an offence.
