Introduction：
Guangzhou will encounter various rainy and foggy weather in summer, which makes the editor who drives to work a little timid.
Driving in the fog will bring many inconveniences to people and easily cause traffic accidents. But in daily life, people cannot avoid traveling on rainy days. So, how to regulate behavior when driving in rainy and foggy weather? What should we pay attention to in order to ensure safety?

What should you check before driving in rainy or foggy weather?
1. Make sure your windshield is clean and tidy. Windshields in rainy and foggy weather are extremely prone to condensation of water droplets and raindrops. Before setting off, it is recommended to remove the mist on the glass to prevent surface mist from accumulating and reducing visibility for subsequent driving
2. Make sure your headlights (including fog lights) are clean, clear and working properly. During driving, you use the lights of your headlights to "communicate" with other drivers. In rainy and foggy weather, visibility is low, so you need to use headlights, fog lights, etc. to judge the behavior of the driver in front. To avoid accidents
3. Check whether the backup energy (fuel, power supply) is sufficient. It is very dangerous to stop or break down in foggy weather. If you fail to give a warning in time, other drivers are likely to fail to react in time, which may lead to accidents.

Tips for driving in foggy weather:
1. Use lights in a standardized manner
Low beam: You must turn on low beam in foggy weather to ensure visibility and avoid strong light refraction.
Fog lights: Turn on only when visibility is less than 100 meters (the red rear fog lights have strong penetration), and turn off immediately after visibility improves to avoid interfering with other vehicles.
Disable high beam: High beam will form diffuse reflection in fog, which will reduce the visible distance.

2. Tips for keeping sight
Defogger + air conditioner: Turn on the front windshield defogger and rearview mirror heating functions simultaneously, and adjust the air conditioner to external circulation mode to avoid fogging due to the temperature difference between inside and outside.
Wiper frequency: Adjust the intermittent gear according to the speed of fog condensation to keep the glass clear.

3. Speed and distance control
3-second rule: Choose a fixed reference point (such as a road sign), count to 3 seconds after the car in front passes, and then reach the safe distance (in foggy weather, it is recommended to extend to 4-5 seconds).
Dynamic deceleration: Quickly scan the rearview mirror before braking, and use the brakes to remind the car behind to avoid sudden braking and rear-end collision.
Speed limit principle: The maximum speed shall not exceed 1/2 of the visibility distance (for example, when the visibility is 50 meters, the speed should be ≤25km/h).

4. Predictive driving
Pay attention to changes in road reflections (which may indicate water or ice).
Large vehicle trails are usually lightly fogged, so you can refer to their driving tracks appropriately but keep a safe distance.

So, when should you turn on the fog lights?
1. Fog lamps are additional front and/or rear lights on some vehicles, designed to improve visibility and identification by vehicle owners in foggy conditions.
2. It divided into front fog lamps and rear fog lamps:
Front fog lamps are usually white or yellow and are located below the headlights, which can penetrate fog without causing glare.
Rear fog lamps are red and have a brightness similar to brake lights. They are located at the rear of the vehicle and help other drivers see you.

What does the fog light symbol look like?
The front fog light symbol is usually green or white, with a semicircle and three lines pointing downwards.
The rear fog light symbol is usually yellow or orange, also a semicircle, but with the lines pointing backwards.
The rear fog light symbol is usually yellow or orange, also a semicircle, but with the lines pointing backwards.
Extended knowledge of fog lights
With the development of the times, "automatic fog lights" have appeared on the market. As the name suggests, automatic fog lights are a car lighting system that automatically senses changes in ambient light and controls the turning on and off of fog lights.
Once the ambient light drops to a preset threshold, the automatic fog lights will automatically start, providing drivers with better lighting effects in bad weather conditions, thereby ensuring driving safety.
It is worth mentioning that the automatic fog light system usually also has an intelligent adjustment function. It can automatically adjust the brightness and illumination angle of the fog lights according to the real-time changes in ambient light to achieve the best lighting effect. This intelligent adjustment not only improves the driver's field of vision, but also helps reduce traffic accidents caused by improper use of lights.

Summary
There are thousands of roads, but safety comes first. When driving in rainy and foggy weather, be careful, careful, and careful again.
Although fog lights are auxiliary lights, they can play a key role in certain important moments. Therefore, the editor recommends that you learn more about the usage of common car lights and learn relevant emergency measures. Safety is important at all times, be cautious at every step.
