HGV Driving Hours Rules for Operators and Drivers

When HGV driving hours rules apply

HGV driving hours are an operator licence control issue, not solely a driver responsibility. If work is planned badly, tachograph data is ignored or infringements are not followed up, DVSA can treat the weakness as an operator management failure rather than an isolated mistake by the person at the wheel.

For most goods vehicles or vehicle combinations over 3.5 tonnes used in the UK or on international work to, from or through the EU, the main rules are the assimilated drivers’ hours rules. GOV.UK remains the legal source; this guide explains how those rules normally need to be controlled in a transport operation.

The main limits operators should plan around

Daily and weekly driving limits

The standard daily driving limit is 9 hours. It may be extended to 10 hours no more than twice in a fixed week, which runs from 00:00 Monday to 24:00 Sunday. A 10-hour day should be planned deliberately and recorded clearly, not used to rescue poor route planning every week.

The weekly driving limit is 56 hours. There is also a 90-hour cap across any 2 consecutive weeks. This rolling two-week view is where many otherwise tidy schedules become exposed. A driver can be legal in week one and still leave the business with very little usable driving time in week two.

Breaks after 4.5 hours of driving

After no more than 4.5 hours of driving, the driver must take a break of at least 45 minutes unless they begin a daily or weekly rest period. The 45 minutes can be split into two parts over the 4.5-hour driving period, but the order matters: the first break must be at least 15 minutes and the second at least 30 minutes.

Operators should look at what the tachograph actually shows, not what the route sheet intended. A 30-minute stop followed by a later 15-minute stop does not create a compliant split break. Break time also needs to be free from work; loading, paperwork, defect reporting or yard movements can undermine the record even when the driver believes they were resting.

Daily rest and weekly rest

A driver must normally complete a daily rest period within each 24-hour period after the end of the previous daily or weekly rest. Regular daily rest is at least 11 continuous hours. Reduced daily rest of at least 9 continuous hours is allowed up to 3 times between weekly rest periods. A regular daily rest can also be split into at least 3 hours followed by at least 9 hours.

Weekly rest must start no later than the end of 6 consecutive 24-hour periods from the end of the previous weekly rest. In any 2 consecutive fixed weeks, the driver must take either 2 regular weekly rests or one regular weekly rest and one reduced weekly rest. A regular weekly rest is at least 45 continuous hours. A reduced weekly rest is at least 24 hours but less than 45 hours, with compensation by an equivalent block of rest before the end of the third following week.

Manual entries and tachograph evidence

Driving under the assimilated rules must be recorded on a tachograph. That record is often the first evidence DVSA or an auditor will review. The recurring weak points are manual entries at the start of shift, after a ferry or rail crossing, after time on another vehicle and at the end of shift. A missing or wrongly coded period of other work, availability or rest can turn an otherwise compliant day into an infringement on paper.

The management question is whether the operator downloads, analyses and acts on the data quickly enough to prevent repeat infringements. A common pattern is a small fleet with good intentions but weak weekly review. Drivers are handed infringement printouts, but no one checks whether the same route, customer delay or depot start time is causing the breach. The file holds paper but it does not show effective control.

“In compliance reviews, the file often fails the same way twice: a missed manual entry on Monday morning, then an unanalysed 4.5-hour break breach a fortnight later. If the debrief does not name the cause and the corrective action, the same driver goes back on the same run with the same problem the following week.” Liam Gafoor CMILT IOSH, transport compliance adviser.

Debrief and repeat pattern evidence

A driver debrief on infringements is what turns a printout into evidence of management control. For each infringement the file should show the date, the rule breached, the driver’s explanation, the operator’s view on root cause, the action taken and any follow-up check. Where the same driver, vehicle, customer or shift start time appears across several weeks, that repeat pattern is the point a Traffic Commissioner will expect to see addressed in writing.

If the only evidence of action is a signature on a generic printout, the audit trail is thin. A short note explaining what changed in the schedule, the route, the customer slot or the driver’s training is far more persuasive than a stack of unread reports.

Operator checks that make the rules workable

• Plan daily, weekly and two-weekly driving time together before allocating work.
• Check split breaks for the correct 15-minute then 30-minute sequence.
• Monitor reduced daily rest so the permitted frequency between weekly rests is not exceeded.
• Track weekly rest timing and any compensation owed for reduced weekly rest.
• Review manual entries for start of shift, ferry or rail crossings, and changes of vehicle.
• Run a weekly infringement debrief that names cause, action and follow-up against each event.
• Flag repeat patterns by driver, vehicle, customer or shift and record the operator response.

When to get the file checked

A drivers’ hours review is worth doing before a DVSA visit, a desk-based assessment, an operator audit, a Transport Manager handover or public inquiry preparation. The output should identify the pattern, the cause and the action needed to stop repeat breaches rather than a generic compliance score.
