Show answer

Correct answer

  • BLuces de emergencia.Hazard warning lights.
Explanation

If your vehicle stops on an autopista because of a breakdown, you must switch on the hazard warning lights to warn other drivers of the obstacle and make things safer. If the vehicle has no hazard warning lights, you must use at least the sidelights. This lets other drivers see the vehicle from far away and slow down, avoiding possible accidents. Switching on only the sidelights or main beam is not enough, because they do not do the same job of signalling a danger.
