1, 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 language of etiquette and greeting. 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 and greets you with a horn when you approach. The language of "Didi" is that cars should overtake, and all vehicles should grasp the scale and be polite to three points. "Di! Hey! " A sound, or a continuous "beep!" Sound, this horn is used because there are many pedestrians and vehicles. Please pay attention to pedestrians and bicycles or make 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 of the honkers behind you are urging you, so let it go if you can! It should be noted that in many large and medium-sized cities, in order to control noise pollution, honking is strictly prohibited in urban areas, and drivers must strictly abide by this regulation. 2. Lighting lamps include: position lights (commonly known as small lights, yellow and red at the front and back, used to indicate the length and width of the car at night), headlights (also called headlights) and turn signals; Danger warning light; License plate light, foot brake light (brake light), reversing light (white), anti-fog light. Brake lights (brake lights) are red and dazzling, which can attract more attention. When you step on the brake pedal, the brake light at the rear of the car will light up to attract the attention of the rear car, indicating that the front car is slowing down. Please note that the rear car should also take corresponding deceleration measures (step on the brake pedal). Turn signal: (1), left turn signal; If the front car is parked on the side of the road, it means it is ready to start; Driving vehicles turn on the left turn signal and may want to borrow the left lane; If you are in front of the intersection, you may have to turn left or turn around; (2) Right turn signal: stop on the right; Turn right; Go back to your driveway after overtaking. Danger warning light: the turn signal flashes at the same time, indicating several situations: (1) towing a broken car, breaking down or the car is in poor condition (driving slowly or parked on the side of the road); (2) If there is an urgent task, tell everyone to avoid it; (3) When the motorcade travels collectively, pay attention to the road; (4) signal that the traffic is opening the door and getting off. Back-up lights: The back-up lights are white and symmetrical. Used for reversing at night to help observe the situation behind the car and remind people next to it to avoid. Position light: When it gets dark in the evening, the position light will light up, and use the rear taillight to signal the vehicles behind, and pay attention to keeping the distance between vehicles; The front light reminds the opposite car to pay attention to the lateral distance. License plate light: it is convenient to identify cars at night; Anti-fog lamps (front and rear): used in foggy, rainstorm and foggy weather, so that adjacent vehicles can identify the distance between vehicles. Headlights (also called headlights): used for driving at night. Switch between high beam and low beam with the change of road surface and vehicle speed. Generally, in urban areas or well-lit roads, you can only use low beam lights when the speed is not fast. In the sections with poor lighting in the suburbs, you can use the high beam with the acceleration of vehicles, but when you meet cars, pedestrians or cyclists, you should use the low beam. When cars meet at night, the two sides will flash high beams. Experienced drivers will stagger the flashing order to shine on each other. After all, the low beam can't be that far. At the intersection, a car flashed. "I thought about it." If the other car doesn't say anything, it is agreed. If the light keeps flashing, it means "I'm in a hurry, let me go first!" " Experienced drivers will let each other, if it is true, hehe, everyone can't pass the light, and there must be friction in the most important thing. The flashing high beam reminds the other party to turn off the high beam when the car passes by, so as not to see the road clearly. Most of the flashing lights in the back car prompt the front car, "Can you hurry up, I want to pass!
