Is it necessary to alternate between high and low beams when overtaking during the day?

[SanLondyn]

When overtaking during the day, it is not necessary to alternate between high and low beams. Instead, you should turn on the left turn signal and honk the horn. Below is some information about daytime overtaking: 1. Regulations on light usage: The "Implementation Regulations of the Road Traffic Safety Law" have clear stipulations regarding the use of lights. Failure to use lights as required will result in a 1-point penalty. During periods when streetlights are on at night, or when driving in conditions of low visibility such as fog, rain, snow, dust, or hail, you should turn on the headlights, clearance lights, and rear position lights. When turning, changing lanes, overtaking, making a U-turn, or pulling over, you should turn on the turn signal 100 to 50 meters in advance. 2. Precautions: Whether during the day or at night, when overtaking on the highway or when you need to alert vehicles in front or behind, try to avoid using the horn. Due to the high speeds on the highway and significant wind noise, the horn is often unclear and less effective.
