Daily rest

HGV 15-hour shift rules explained.

The “15-hour shift” is not a separate allowance to work or drive continuously for 15 hours.

The short answerThe phrase usually describes the maximum spread between duties when only nine hours of daily rest fits inside the required 24-hour window. It does not create 15 hours of driving or working time.

Where does 15 hours come from?

A new daily rest period normally has to be completed within each 24-hour period after the end of the previous daily or weekly rest. If daily rest is reduced to nine hours, the remaining spread can be up to 15 hours.

Why spread is not the same as working time

The spread can contain driving, other work, POA and breaks. Separate daily driving, break and working-time rules continue to apply.

How often can daily rest be reduced?

Under the assimilated rules, daily rest may generally be reduced to at least nine hours no more than three times between weekly rest periods. Check the current official guidance and any applicable exemption.

Common questions

Can I drive for 15 hours?

No. The normal daily driving limit is nine hours, extendable to ten hours no more than twice in a fixed week.

Is every long shift a reduced-rest day?

The actual rest completed within the relevant 24-hour period determines whether daily rest was regular or reduced.
