Turn on the fog lights, low beam lights, clearance lights, front and rear position lights, and hazard warning flashers. The following are specific details: 1. When visibility is less than 50 meters: Turn on the fog lights, low beam lights, clearance lights, front and rear position lights, and hazard warning flashers. The speed should not exceed 20 kilometers per hour, and you should exit the highway from the nearest exit as soon as possible. 2. When visibility is less than 100 meters: Turn on the fog lights, low beam lights, clearance lights, front and rear position lights, and hazard warning flashers. The speed should not exceed 40 kilometers per hour, and you should maintain a distance of more than 50 meters from the vehicle in front in the same lane. 3. When visibility is less than 200 meters: Turn on the fog lights, low beam lights, clearance lights, and front and rear position lights. The speed should not exceed 60 kilometers per hour, and you should maintain a distance of more than 100 meters from the vehicle in front in the same lane. 4. Notes: If fog lights are not installed, turn on the small lights and running lights of the vehicle. If the car is stationary, turning on the hazard warning flashers is acceptable, but they should not be used while driving.

When visibility drops below 50 meters in heavy fog, I always turn on the fog lights immediately, especially making sure both front and rear fog lights are illuminated. Front fog lights are usually yellow or white, helping to penetrate the fog and improve road visibility; rear fog lights are bright red, making your vehicle noticeable to following cars from a distance and preventing rear-end collisions. Never use high beams, as they reflect off the fog and cause glare, making driving even more dangerous. Additionally, I recommend slowing down significantly and maintaining a safe following distance. It's also a good idea to check if your tires and wipers are in good condition. Once, I encountered heavy fog on the highway and safely passed through by using fog lights—experience tells me that ignoring these details can lead to accidents. Pay attention to your lighting system during regular maintenance to avoid issues in emergencies. Stay calm, focus on driving, and prioritize safety.

When driving in heavy fog with visibility below 50 meters, I always turn on the fog lights. The front fog lights help me see the road ahead, while the rear fog lights ensure that vehicles behind don't collide with me. I never use high beams as they make the fog appear brighter and reduce visibility. With over a decade of driving experience, I've noticed that most fog-related accidents stem from improper light usage. It's crucial to reduce speed and maintain ample space; keeping windows clean is also important. If the fog is too thick, I find a safe spot to pull over for a while. Using the car's air conditioning helps prevent window fogging, and navigation assists in avoiding hazardous areas. Make it a habit to check if your fog lights are functioning properly—don't wait until the last minute. Remember, lights are your lifeline in foggy conditions, and caution ensures long-term safety.

Turn on the fog lights. Both front and rear fog lights should be on, and don't hesitate if visibility drops below 50 meters in heavy fog. Front fog lights help with illumination, while rear fog lights make you visible to other vehicles. Avoid using high beams as they can cause glare and create more trouble. Slowing down is crucial, and increasing the following distance enhances safety. Check if your lights are functioning properly—early detection means early repairs. Foggy conditions are hazardous, so stay focused and avoid distractions. If necessary, pull over and wait for the fog to lift—better safe than sorry. Safety comes first.

What Technologies Are Used in Autonomous Driving?

Autonomous driving utilizes the following technologies: 1. Sensor Technology: Autonomous vehicles are equipped with various sensors around the car to recognize the surrounding environment, roads, and traffic conditions. 2. Chip Technology: This refers to super chips, akin to small computers, capable of processing data collected by multiple sensors and integrating them. This significantly reduces the size and cost of the vehicle's 'central computer' and makes its application in cars feasible. 3. Operating System: The computer control system combines processing results with operational hardware to achieve acceleration, deceleration, braking, parking, steering for avoidance, and human-machine interaction, among others. 4. Network Technology: For driverless cars to be road-ready, they must have internet and local area network connectivity and recognition capabilities. This includes vehicle-to-vehicle communication, satellite communication, weather forecast connectivity, and interaction with traffic command networks. These capabilities enable the car to correctly identify and choose routes, obey traffic police commands, make correct decisions at intersections, and avoid dangers to ensure safe driving.

Why is the car air conditioning slow to start?

Possible causes include a damaged blower motor, a clogged air filter, a faulty air door actuator, or a stuck air blend door. Here is an introduction to car air conditioning: 1. Overview: Car air conditioning refers to the air conditioning system installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. 2. Structure: It generally includes refrigeration, heating, and ventilation systems. This integrated design makes full use of the limited space inside the vehicle, featuring a simple structure and easy operation, making it the internationally popular modern car air conditioning system. 3. Layout: Different types of air conditioning systems have varying layouts. Currently, most passenger cars use a combined heating and cooling system. The typical arrangement integrates components such as the evaporator, heater core, centrifugal blower, and control mechanisms into a single unit, known as the air conditioning assembly.

Meeting or Passing Vehicles?

It refers to passing, which means trains, cars, etc. traveling in opposite directions crossing at a certain point. Below are relevant introductions about passing: 1. Methods for facing passing: The passing sign, where the upward arrow represents yourself. If your arrow is large (black or white), it means you have the right of way (you go first); if your arrow is small (red), it means you must yield (the other party goes first). Proper passing requires preparation in advance to avoid psychological panic and operational confusion during passing. 2. Regulations to follow: On roads without centerlines, narrow roads, or narrow bridges, you should slow down and pass on the right, paying attention to the safety of non-motorized vehicles and pedestrians. When passing is difficult, the party with the condition to yield should let the other party go first. On obstructed road sections, the party with the obstruction should yield. On narrow slope sections, the party with the obstruction should yield, etc.

How much to turn the steering wheel when making a left turn at an intersection?

When turning at an intersection, the amount of steering wheel turn depends on the size of the turn. The smaller the intersection, the greater the angle of the steering wheel turn for a left turn. Turning too much at a large intersection may lead to driving in the opposite direction, especially when making a left turn across two or three lane lines. If the vehicle is in the right lane line and the steering wheel is turned too much, it may affect the left-turning vehicles on the left. The correct method is to first turn the steering wheel slightly less than half a turn, and if it feels insufficient, add a little more to make it just right. Below are some techniques for turning at intersections: 1. Turn the steering wheel one full turn for a left turn. 2. For a small left turn intersection, turn the steering wheel one full turn, and add a little more if it's not enough. 3. For a large left turn intersection, first turn the steering wheel half a turn, and add a little more if the angle is insufficient.

Should You Press the Brake When Engaging the Clutch for Starting?

When starting the car, it is necessary to press the brake pedal while engaging the clutch, primarily to prevent the car from rolling forward. This starting sequence of pressing both the clutch and brake should be followed whether driving on flat roads or steep slopes, mainly for safety reasons. Relevant information is as follows: 1. Starting: On flat roads, you can directly press the clutch without needing to press the brake, relying on the clutch to control the car's speed. Once the car starts moving, you can fully release the clutch. If the car is on a slope, it is best to press the clutch while also pressing the brake to prevent the car from rolling back or suddenly lurching forward. 2. Note: When not pressing the brake, you can use the handbrake. Once the car's semi-engagement point is found, releasing the handbrake will prevent the car from rolling back. The primary function of the car's clutch is to ensure a smooth start, so for the safety of the car, it is essential to follow driving rules when operating the vehicle.
