Correct answer
- BCuando el vehículo no pueda alcanzar la velocidad mínima exigida y exista peligro de colisión por alcance.When the vehicle cannot reach the required minimum speed and there is a risk of being hit from behind.
Under Article 49.3 of the General Traffic Regulations (RGC), if the vehicle cannot reach the required minimum speed and there is a risk of being hit from behind, you must drive with the hazard warning lights on, by day and by night. They are also used, among other cases, when the vehicle is immobilised on a motorway (autopista) or dual carriageway (autovía) or in poor visibility.
Cuando un vehículo no pueda alcanzar la velocidad mínima exigida y exista peligro de alcance, se deberán utilizar durante la circulación las luces indicadoras de dirección con señal de emergencia.Read the full rule
