DGT rules in English

Incidents, maintenance, and environmental rules

These rules cover accidents, breakdowns, tyres, and carrying loads.

Accident response is protect, alert, help

At an accident: prevent more danger first, call emergency services, then help without making injuries worse.

Watch for: The question mentions being involved in or witnessing an accident.

→

An immobilized vehicle becomes a signal problem

A broken-down vehicle is a hazard. Make it visible to other drivers as quickly as possible.

Watch for: The question mentions a breakdown, emergency lights, warning triangles, or stopping on the shoulder.

→

Tyres are safety equipment

Tyre condition directly affects grip, stopping distance, and control. Don't wait for a tyre to fail before acting.

Watch for: The question mentions tyre pressure, tread depth, wear, aquaplaning, or puncture.

→

Load changes vehicle behavior and visibility

Loads affect how the vehicle handles and whether your lights and signals are visible to others.
