# HGV Hours Calculator

> Free HGV drivers' hours calculator: enter hours driven today, this week and last week to see driving time left and when your 45-minute break is due. GB/EU rules.

## Key facts

- An HGV driver in the UK can drive at most 9 hours a day, extendable to 10 hours no more than twice in a fixed week, under the assimilated EU rules.
- Driving is capped at 56 hours in a single fixed week and 90 hours in any two consecutive weeks, so a 56-hour week leaves at most 34 hours the next week.
- A break of at least 45 minutes is required after 4.5 hours of driving; it can be split into 15 minutes then 30 minutes, in that order.
