Driving Hours Gone Wrong? The Legal Lifeline You Might Be Missing

When driving hours go wrong — whether due to a breakdown, unexpected traffic, or extreme weather — it can feel like you’re out of options. For HGV drivers, sticking to the rules around assimilated hours is critical, but sometimes the road throws up situations you couldn’t plan for.

That’s where Article 12 of Regulation (EC) No 561/2006 (as retained in UK law) steps in. It’s a legal safeguard for genuine emergencies — but not something you can rely on just to finish your shift.

How Article 12 Helps When Driving Hours Go Wrong

Article 12 allows drivers to temporarily exceed driving time limits if doing so is necessary to protect safety and reach a suitable stopping place. It’s intended for unforeseen circumstances that occur during a journey, not poor planning or wishful thinking.

What Does Article 12 Allow?

Safety Comes First

You can only apply Article 12 if safety is at risk — for yourself, others, your vehicle, or your load. You’re permitted to continue driving past your limit, but only to the nearest suitable and safe stopping point.

Extensions for Rest Purposes

Under exceptional conditions, you can extend your driving time, but only for the purpose of returning to your home or your employer’s operational centre to begin a weekly rest period:

By up to 1 hour to reach your home or depot for a weekly rest
By up to 2 hours to reach your home or depot for a regular weekly rest, but only after taking a 30-minute break beforehand

This helps in those rare moments when driving hours go wrong, and you’re genuinely stuck.

Valid Reasons for Article 12 Use

You can only use this exception if something genuinely unforeseeable occurs while you’re driving:

Sudden, severe weather (e.g. flash floods, black ice)
Major accidents or road closures
Vehicle breakdowns
Unexpected ferry or tunnel disruptions

Your Legal Responsibilities as a Driver

Even when driving hours go wrong, you must stay compliant by:

Recording the Exception

Make a manual tachograph entry explaining the reason for the breach — clearly and accurately — before or as soon as you reach your stopping point.

Limiting the Deviation

Drive only as far as needed to get to a safe location. Article 12 is not permission to complete your delivery.

Compensating the Time

Any extra driving time must be compensated by taking an equivalent rest period — in one block — within three weeks.

What Article 12 Does Not Allow

Planning routes that knowingly breach hours
Using delays as a blanket excuse
Extending your shift to meet delivery targets

If driving hours go wrong due to poor planning or avoidable issues, Article 12 won’t cover you — and enforcement agencies know the difference.

What Happens If You Misuse Article 12?

Fines for tachograph violations
Risk to your operator’s licence
Possible vehicle immobilisation
Prosecution for serious or repeated breaches

Using Article 12 too often, or without proper records, can flag you for investigation. Be honest, be accurate, and document everything.
