Must the driver of a vehicle immobilised because of a breakdown outside the carriageway and hard shoulder place the hazard warning device?

Correct answer

No, because it does not obstruct traffic.

The driver of a vehicle immobilised because of a breakdown outside the carriageway and hard shoulder is not required to place the hazard warning device to warn of its presence, because it does not obstruct traffic. When a vehicle is immobilised because of a breakdown on the carriageway or hard shoulder, the obstruction created must be marked to alert other drivers and prevent accidents. A light-emitting hazard warning device must be placed and activated or, alternatively, until 1 January 2026, hazard warning triangles must be placed at an appropriate distance. However, if the vehicle is outside the carriageway and hard shoulder, it does not represent an obstruction to traffic, so the hazard warning device is not required.
