DGT Rules Incidents, maintenance, and environmental control

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.

Watch for: The question mentions cargo, luggage, protruding loads, or covered lights.
