You’re driving at night with your headlights on main beam. A vehicle overtakes you. When should you dip your headlights?

Explanation: On main beam, your headlights are liable to dazzle a driver who's overtaken you. For this reason, you should dip your headlights as soon as the overtaking vehicle passes you. When following another vehicle at night, make sure that your headlights are on dipped beam and the light beam falls short of the vehicle in front.
