266. Breakdown
A breakdown occurs when a vehicle can no longer continue safely because of a mechanical, electrical or other technical problem. If possible, move the vehicle away from moving traffic, switch on the hazard warning lights and warn other road users. On high-speed roads, leave the vehicle only when it is safe to do so and wait in a protected place away from traffic. Contact roadside assistance or emergency services when necessary, and do not attempt repairs that put you or others in danger.
What should you do if your vehicle breaks down in Belgium?
If possible, move the vehicle off the carriageway or to a place where stopping and parking are permitted. Warn other road users and arrange assistance when the vehicle cannot continue safely.
When must you use the warning triangle after a breakdown in Belgium?
If the vehicle cannot be moved or can only be left where stopping or parking is prohibited, it must be signalled with the warning triangle. Under the current rules, the triangle is placed at least 100 metres away on a motorway and at least 30 metres away on other roads, where possible.
Do you have to wear a reflective vest after a breakdown in Belgium?
Yes. When a vehicle breaks down on a motorway or road for motor vehicles at a place where stopping or parking is prohibited, the driver must wear a retro-reflective safety vest when leaving the vehicle.
