# Explanation
According to traffic regulations, when a vehicle becomes immobilized on the roadway due to an emergency, the driver **must mandatorily place the hazard warning triangles** as a general safety measure. This is necessary on both urban and interurban roads, even if the hazard lights or position lights have already been turned on. The triangles complement these light signals and better warn other drivers of the obstacle.
