What lights to use when passing through an intersection ahead?

[JamesRose]

When driving straight through an intersection with traffic signals ahead, simply use the low beam. If passing through an intersection without traffic signals, you should alternately switch between high and low beams more than twice, slow down in advance, and use the alternating high and low beams to signal while closely monitoring the traffic conditions ahead. Here are the specific details: When overtaking: When overtaking at night, turn on the turn signal in advance and observe the vehicles behind. If the following vehicle is too close, it is not advisable to signal and overtake, as this may easily catch the following vehicle off guard. When changing lanes: To prevent the vehicle ahead from changing lanes during overtaking, it is essential to alert the other driver by honking or quickly switching between high and low beams. Observe the vehicle ahead; if there is no intention to change lanes, you can then accelerate to overtake. If the vehicle ahead turns on the left turn signal, it indicates an emergency situation ahead, making it an unsuitable time to overtake, as the vehicle also needs to change lanes.
