What lights to use when passing through an intersection ahead?

[Young]

There are several situations for using lights when passing through an intersection ahead: 1. Going straight: If going straight through an intersection with traffic lights ahead, use low beams directly. If passing through an intersection without traffic lights, alternate between high and low beams more than twice, slow down in advance, and signal by alternating between high and low beams while paying close attention to the traffic conditions ahead. 2. 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 recommended to overtake with the turn signal on, as this may easily catch the following vehicle off guard. 3. When changing lanes: To prevent the vehicle ahead from changing lanes while overtaking, try to remind the other party by honking or quickly switching between high and low beams to alert the vehicle ahead. Observe it at this time. If there is no intention to change lanes, you can accelerate to overtake; if the vehicle ahead turns on the left turn signal, it indicates an emergency situation ahead and is not a good time to overtake, as it also needs to change lanes.
