What Is the HGV Working Time Directive UK?

The HGV Working Time Directive UK is part of the road transport working time rules for mobile workers. Its purpose is to reduce fatigue, protect drivers and improve road safety by limiting total working hours.

It applies to working time, not just driving time. This means a driver must consider all work carried out during the shift, not only the time shown as driving on a tachograph.

Maximum Weekly Working Time for HGV Drivers

Under HGV WTD rules, a mobile worker must not exceed an average of 48 hours per week over the relevant reference period. In any single week, work can go up to 60 hours, but only if the 48-hour average is maintained.

This is why one busy week does not automatically mean a breach, but repeated high-hour weeks can create compliance problems. Transport managers should monitor weekly totals and reference-period averages.

Break Requirements Under HGV WTD Rules

HGV WTD breaks are based on total working time. If total working time is more than 6 hours but not more than 9 hours, breaks must total at least 30 minutes. If working time exceeds 9 hours, breaks must total at least 45 minutes.

Breaks should interrupt working time and are normally taken in blocks of at least 15 minutes. These WTD break rules sit alongside tachograph break rules, so drivers should check both.

For detailed break examples, read our HGV Breaks and Rest Periods UK guide.

Night Work Rules for HGV Drivers

Night work under road transport WTD rules is generally limited to 10 hours in a 24-hour period, unless a valid workforce agreement allows a different arrangement. Goods vehicle night-time is commonly treated as the period including midnight to 4am.

Night shifts create higher fatigue risk, so drivers and operators should be especially careful with duty length, break timing and accurate records.

What Counts as Working Time?

Working time can include driving, loading, unloading, cleaning, vehicle checks, paperwork, maintenance-related duties, dealing with customers and any time when the driver is required to be at the employer’s disposal and carrying out work duties.

Periods of availability may not count as working time in some situations, but they must be recorded correctly. Misusing POA can create inaccurate records and compliance risk.

For recording issues, read our Tachograph Rules UK guide.

Why Drivers Confuse WTD and Driving Hours

Driving hours rules mainly control driving, breaks from driving and rest periods. The HGV Working Time Directive UK controls total working time. A driver may have enough tachograph break time but still fail WTD working time requirements.

This is common when drivers do long loading times, yard work, paperwork or vehicle checks before and after driving. The tachograph record must reflect these activities correctly.

Penalties and Compliance Risk

Failing to comply with HGV WTD rules can create risk for both drivers and operators. Problems may arise during DVSA roadside checks, operator audits, tachograph analysis or internal compliance reviews.

Repeated failures can contribute to fines, investigations, operator licence concerns and employment issues. For wider enforcement guidance, read: DVSA Checks UK and HGV Penalties and Fines UK.
