UK driver hours are not checked the way most drivers think.
Tachograph infringements are usually caused by mixing concepts: fixed week, working week, rests and limits.
This site explains driver hours the way they are actually checked in inspections — not how they are commonly explained online.
What most drivers get wrong
Many drivers know the rules — but still plan weeks incorrectly.
The most common mistakes come from mixing:
• working week vs fixed week
• daily and weekly rest
• when limits actually reset
A tachograph can look clean — and still fail an inspection.
