After driving through a stretch of dense fog with the rear fog light on, visibility improves. What should you do?
En español: Tras circular por un tramo de niebla densa con la luz antiniebla trasera encendida, la visibilidad mejora. ¿Qué debe hacer?
Why this is the correct answer
You must switch off the rear fog light as soon as visibility improves, since its high intensity dazzles and annoys the drivers behind once it is no longer needed.
