What is the Car Light Signal Mnemonic?

[LeIvan]

Emergency help: three high beams followed by three hazard lights; Please pay attention to behavior: long press high beam for three seconds; There is a problem with the car, please pull over and check: one honk followed by three high beams; I have an urgent matter, please give way: one honk followed by one high beam; Best wishes: two honks followed by two high beams; Sorry: three hazard lights; It's okay: three high beams; Thank you: three hazard lights; You're welcome: three high beams. Car light signals are as follows: 1. Overtaking or when the car in front doesn't move after the light turns green: flash high beam once. If you notice a problem with a neighboring car: flash high beam three times. 2. When encountering strong lights at night that dazzle you: flash high beam twice as a reminder, turn on hazard lights to show dissatisfaction; When merging lanes while driving: one high beam flash means "agree", continuous high beam flashes mean "refuse". 3. When the car behind is following too closely: intermittently flash brake lights. To remind pedestrians or non-motorized vehicles to pay attention: continuously flash high beams, switching from low beam to high beam. Emergency braking: turn on hazard lights promptly; Thanks: hazard lights for three seconds.
