You are driving at night on an unlit road with main beam on and a vehicle approaches from the opposite direction. What should you do?
En español: Circula de noche por una vía sin iluminación con la luz de carretera encendida y se aproxima un vehículo en sentido contrario. ¿Qué debe hacer?
Why this is the correct answer
You must switch to dipped beam so as not to dazzle the oncoming driver. Glare can momentarily blind them and cause an accident.
