Daily Driving: 9 Hours, and 10 Hours Twice in the Week

What this article covers

Under assimilated Regulation (EC) 561/2006, daily driving time is normally 9 hours. You may extend that to 10 hours — but only twice during the week.

This page is only about that daily driving ceiling. It is not the 56-hour / 90-hour totals, not working-time night work, and not reduced daily rest.

Normal day: 9 hours

Driving time is the time recorded as driving. Stay at or under 9 hours and you have not used an extension that day. Breaks and rest still have to be legal on their own rules — a clean 9-hour driving day can still be illegal for other reasons.

10 hours, twice in the week

You may drive up to 10 hours on a day, not more than twice during the week.

For this rule, a week is the drivers’ hours week: 00:00 Monday to 24:00 Sunday. It is not “twice between weekly rests”. That between-weekly-rests count belongs to reduced daily rest, not to 10-hour driving days.

• A day with more than 9 hours of driving, up to 10 hours, uses one of the two extensions.
• A third day over 9 hours in the same Monday–Sunday week is outside the rule.
• Any day over 10 hours of driving is an infringement, even if you still had an extension left.

Examples

OK: Monday 8h40 (no extension). Thursday 9h50 (first extension). Saturday 9h20 (second extension). Other days at or under 9 hours.

Fail: Three days in the same Monday–Sunday week with more than 9 hours of driving — even if none of them reaches 10h20.

Fail: One day of 10h20. That is over the 10-hour cap, not a lawful extension.

What this limit does not replace

Staying inside 9 or 10 hours of driving does not make the day legal by itself. The 4.5-hour driving break, daily rest and weekly rest stay separate. A 10-hour driving day also still counts toward the 56-hour week and the 90-hour fortnight.

On this site’s timesheet

The 10h driving extensions card counts days in the current Monday–Sunday week where driving went over 9 hours, against a cap of two. It is an aid. It does not replace the tachograph record.

Article 6(1) of Regulation (EC) 561/2006 (as it has effect in the UK). Article 4 defines the week as Monday 00:00 to Sunday 24:00. GOV.UK restates the same “10 hours twice in a fixed week” rule.
