Conventional lights have 2 modes: low light – close light and headlight – far light. Ignoring how to use these two lights for lighting purposes (learned right from the moment I started driving), in this article I want to give you a more general overview of using headlights to ask for directions. (passing) and use headlights in case of yielding (passing).

Use your headlights to ask for the way/give way

Headlights for passing (Passing)

Using car horns in Vietnam is considered inevitable. With the current traffic situation, if not using the horn, it is difficult to ask to pass. However, with good soundproof cars, the horn is difficult to hear and easily confused. At that time, Passing lights are the most effective option. On some new motorcycles today, the manufacturer has also deliberately put the Passing button on the switch to adjust the headlights. When the Passing light flashes in the rearview mirror of the car, the driver will quickly realize that a vehicle is asking to pass.

In some developed countries that I have been tested: Germany, the Netherlands, France…, road users almost only use lights to pass. Even when traveling on the highway, just go at a higher speed than the car in front and turn on the left turn signal, immediately the car in front will know the intention to change lanes to give way to the car behind to pass.

Headlights give way (give way)

If you are a road user, you must have encountered a case: Entering a narrow road with an obstacle ahead, the car coming from the opposite direction flashed towards you. In some European countries that I have known, they all have a common convention: When a car flashes its headlights, it means that the person flashing the lights intends to give way to another vehicle. For example, in the case of a narrow road and both vehicles encounter an obstacle in the middle, the vehicle that flashes the headlights will be the vehicle standing to let the other vehicle pass.
