What lights to use when driving behind another vehicle at night?

[McVivian]

When driving behind another vehicle at night, use low beam headlights. If you need to alert the vehicle ahead, you can flash your high beams. Below are specific details on using low beam headlights: Meeting other vehicles: When meeting or when there is oncoming traffic, turn off your high beams. The glare from high beams can make it difficult for the driver of the oncoming vehicle to see the road ahead, increasing the risk of an accident. If an oncoming vehicle does not turn off its high beams, you can alternately switch between high and low beams to signal them to turn off the high beams. When passing through a dimly lit intersection, alternately use high and low beams and sound your horn. Overtaking: When preparing to overtake, first alternately switch between high and low beams and sound your horn to alert the vehicle ahead of your intention to overtake. Then, turn on your left turn signal, check the rearview mirror for any approaching vehicles, and if the coast is clear, change lanes to the left and accelerate to overtake.
