What lights to use when passing through an arch bridge at night?

[IvanDella]

When passing through an arch bridge at night, it is necessary to alternate between high and low beams for the following reasons: 1. According to the Road Traffic Safety Implementation Regulations. 2. When a motor vehicle passes through a sharp curve, slope, arch bridge, crosswalk, or intersection without traffic signal control at night, it should alternate between high and low beams twice as a signal. Precautions for passing through an arch bridge at night are as follows: 1. Driving uphill: Accelerate in advance to climb the slope, alternate between high and low beams to signal, and alert oncoming vehicles and pedestrians. 2. When approaching the top of the slope: Control the speed appropriately, switch from high beam to low beam to prevent dazzling oncoming drivers and causing loss of vehicle control. 3. Driving downhill: Turn on the high beam to increase the range of visibility.
