What does it mean for a car to honk twice?

Remind the car in front that there is a car coming behind.

The horn is the sound of the car, reminding others to pay attention, overtaking and even greeting each other. The sound of "earth" represents a kind of etiquette and a greeting language. The voice is soft and short, which makes people feel very comfortable. When you meet a car on a narrow road, everyone politely gives way to each other. When you approach, you will greet each other with a megaphone.

The language of "Didi" is that cars want to overtake, so all vehicles should grasp the scale and be polite. "Di! Hey! " The sound is still continuous "beep!" Sound, this horn is used because there are many pedestrians and vehicles. Please pay attention to pedestrians and bicycles or give way.

When going up and down the slope, if a car makes a long noise, "di-" means "please make way quickly, I can't stop!" Most people who honk at the back are urging you, so let them go if you can!

It should be noted that in many large and medium-sized cities, in order to control noise pollution, it is strictly forbidden to whistle in urban areas, and drivers must strictly abide by this regulation.

Don't mess with the lights.

Car lights can't be used at will. Article 47 of the Regulations for the Implementation of the Road Traffic Safety Law clearly stipulates that when a motor vehicle overtakes, it should turn on the left turn signal, change the use of the far and near lights or honk the horn in advance.

On a road without a road center line or with only one motor vehicle lane in the same direction, when the front vehicle meets the rear vehicle and signals overtaking, it should slow down and make way to the right if conditions permit. After confirming that there is enough safety distance, the rear car should overtake the front car on the left side, turn on the right turn signal, and drive back to the original lane after pulling a necessary safety distance from the overtaken car.

Many drivers can't use the high beam well. The "Implementation Regulations" clearly stipulates the use of high beam lights: when passing at night, use low beam lights at the opposite distance 150 meters, and use low beam lights when narrow roads, narrow bridges and non-motor vehicles meet.

When a motor vehicle runs at night without street lamps, with poor lighting or in low visibility conditions such as fog, rain, snow, dust and hail, it shall turn on the headlights, position lights and rear position lights. However, when the rear vehicle driving in the same direction is close to the front vehicle, it is not allowed to use the high beam. According to the relevant regulations, failure to use the lights according to the regulations will result in a fine of 100 yuan, with a score of 1.
