When should you dim your headlights when following another vehicle at night?

  1. When passing them

  2. As soon as you can see their taillights in your mirrors

  3. When the vehicle in front of you brakes

  4. After you have passed them

The correct answer is: As soon as you can see their taillights in your mirrors

When driving at night and following another vehicle, you should dim your headlights as soon as you can see the other vehicle's taillights in your mirrors. This is because your headlights may temporarily blind the driver in front of you, creating a dangerous situation for both of you. Option A and D are incorrect because they suggest dimming your headlights after passing the other vehicle, which is too late. Option C is also incorrect because braking has no relation to when you should dim your headlights. It is important to follow this rule for the safety of everyone on the road.
