Reduced Daily Rest of 9 Hours: When Is It Allowed?

What this article covers

A regular daily rest is 11 consecutive hours. You may reduce it to at least 9 consecutive hours — but only up to three times between two weekly rest periods.

This page is only that reduction. It is not the reduced weekly rest / 3-week compensation rule, and it is not the 3+9 split daily rest pattern.

Regular vs reduced daily rest

Under assimilated Regulation (EC) 561/2006:

• Regular daily rest — at least 11 consecutive hours
• Reduced daily rest — at least 9 consecutive hours and less than 11

You may take a reduced daily rest at most three times between two weekly rest periods. A fourth reduction in that stretch is outside the rule.

This count does not reset at Monday 00:00. It resets when a weekly rest (at least 24 hours) ends. That is a different clock from the two 10-hour driving extensions, which use the Monday–Sunday week.

No compensation block for this reduction

Unlike a reduced weekly rest, a reduced daily rest of 9 hours does not create a “pay these hours back later” debt. The cost is that you have spent one of your three allowed reductions. There is nothing to attach to a later rest to “make up” the missing two hours.

What the reduction does not give you

• It does not remove the break after 4.5 hours of driving
• It does not raise the daily driving limit by itself
• It does not replace weekly rest

It only shortens the continuous daily rest that day, within the three-time limit. A duty long enough that only about 9 hours remain before the next start is, in practice, a reduced rest — even if you later sleep longer.

Not the 3+9 split

Split daily rest (3 hours then 9 hours, 12 hours in total) is a different lawful pattern. Used correctly, it is treated as a regular daily rest, not as one of the three reductions. Getting the order or the totals wrong does not turn it into a reduced rest — it can be an infringement.

Examples

OK: Between weekly rests you take 9-hour daily rests on three days, and 11-hour rests on the others.

Fail: A fourth 9-hour daily rest in the same stretch between weekly rests.

Confusion to avoid: A messy night that is neither a clean 9 nor a clean 11, then labelled “reduced” after the fact.

On this site’s timesheet

The reduced daily rests card counts reduced daily rests detected since the last weekly rest, against a cap of three. It is an aid. It does not replace the tachograph record.

Official source

Article 8 of Regulation (EC) 561/2006 (as it has effect in the UK): a daily rest of at least 9 hours but less than 11 hours is a reduced daily rest, and a driver may have at most three of those between any two weekly rest periods. GOV.UK restates the same limit.
