You are carrying a heavy load in the rear of the vehicle. How does this affect the headlights?
En español: Lleva una carga pesada en la parte trasera del vehículo. ¿Cómo afecta esto a los faros?
Why this is the correct answer
A heavy load in the rear tilts the vehicle backwards and raises the headlight beam, which can dazzle oncoming drivers. This is why the headlight height must be adjusted according to the load.
