All drivers must be aware in advance
Eight precautions for safe driving on foggy days
Please check your "fog"!
01 Use car lights correctly
When driving in foggy weather, turn on the fog lights, marker lights or low beam lights in time, and turn on the hazard warning flashing lights if you are driving on the highway or when the fog is very thick. Remember not to use high and low beams, because the high beams shine upwards, and the light emitted is diffusely reflected by the fog, which will form a white expanse in front of the car, and you will not be able to see anything when driving. In addition, the windshield wipers can be used intermittently to scrape off small droplets of water condensed by fog on the windshield to improve visibility.
02Keep your speed low
The greater the haze, the shorter the viewing distance, and the lower the speed must be. When the visibility is less than 200 meters and more than 100 meters, the speed shall not exceed 60 kilometers per hour; When the visibility is less than 100 meters and more than 50 meters, the speed shall not exceed 40 kilometers per hour; When the visibility is within 30 meters, the speed should be controlled below 20 kilometers per hour; If it is within 10 meters, it is recommended to find an absolutely safe place to park.
03Don't overtake blindly
If you notice a vehicle parked on the right in front of you, don't blindly overtake because it's likely waiting for oncoming traffic to pass. When overtaking a vehicle parked on the side of the road, after confirming that it has no intention of starting and there is no oncoming traffic on the opposite side, honk the horn at the right time and bypass it at a low speed on the left. In addition, when driving on curves and slopes, you should slow down in advance to avoid changing speeds, stopping or turning off the engine in the middle of the road.
04Don't slam on the brakes
Don't slam on the brakes when driving in heavy fog. Sudden braking can easily cause the driver of the car behind to react and cause a rear-end accident, and if it is on the highway, it is more likely to cause a series of rear-end traffic accidents.
If you need to brake, you can tap the brake continuously, one is to control the speed of the vehicle, and the other is to brighten the tail light when braking, which can remind the vehicles behind to pay attention to keeping the distance.
05 honk frequently
In foggy weather with poor visibility, honking your horn frequently can help other motorized vehicles, non-motorized vehicles and pedestrians determine your position and prevent accidents more effectively.
When you hear the horn of another car, you should immediately sound the horn in response to remind yourself of your driving position.
06 The air conditioner is set to internal circulation
When driving on smoky days, try not to open the windows for ventilation. In order to avoid being isolated in the car for a long time, it is recommended to set the air conditioning in the car to the internal circulation mode, which can effectively circulate the air in the car and reduce the entry of inhalable particles.
07Emergency treatment in case of traffic accidents
In the event of a traffic accident in foggy weather, a warning sign should be set up behind the vehicle and the vehicle's hazard warning flashing lights should be turned on to alert the vehicle behind. After the warning, the personnel in the car should immediately withdraw to a safe place, and at the same time call the police, do not stay in the car or walk on the lane to avoid secondary accidents.
08When visibility is too low, stop and wait for the fog to clear
When visibility is less than 10 meters, drive to a roadside safety zone or parking lot and wait for visibility to improve before hitting the road. If you must drive in fog, you must choose the driving speed that can stop quickly in the event of a foggy situation according to the visibility situation (the sight distance must be greater than the braking parking distance).
Keep these in mind
