Correct answer
- BSí, debe encender las luces de emergencia o intermitentes.Yes, you must switch on the hazard warning lights.
During the day and in clear weather, you must use the hazard warning lights when a vehicle stops on the road because of an emergency. These lights warn other drivers that the vehicle is immobilised in an abnormal situation, which helps prevent accidents. Also, if the stop happens at night or in poor visibility, you must also switch on the sidelights so that the vehicle can be seen from a suitable distance, especially if it is in a place where it could be a danger to other road users.
