Safety tips for driving in foggy weather
Use lights properly
Drive at low speeds Keep your distance between vehicles
Try to avoid overtaking
Foggy weather has low visibility, which is not conducive to observing adjacent lanes and oncoming vehicles, so try to avoid overtaking. At the same time, you should not roll the line, otherwise there will be a risk of collision with the opposite vehicle, and you should slow down when driving on curves and slopes.
Don't brake suddenly
Sudden and sudden braking, the car behind often has no time to react, resulting in a rear-end collision. If you need to brake, you can tap the brake several times in a row, which not only serves as a reminder to the car behind, but also helps control the speed of the car.
Horn prompts
When driving in foggy weather, you can honk the horn if necessary, which helps other motor vehicles, non-motor vehicles and pedestrians to judge your position and effectively prevent accidents.
Clear the window fogging
Foggy days are more common in autumn and winter, when the temperature is low and the inside of the car is prone to fogging. Functions such as front and rear window defogging and rearview mirror defogging should be enabled in time, and the air outlet should be facing the front windshield to eliminate fogging in the car. If necessary, you can also prepare some defogging agent and put it in the car for later use.
Handle accidents correctly
When the driver can no longer drive forward due to low visibility or accidents, the driver should park the vehicle in the emergency lane in time according to the actual situation at the scene, turn on the hazard warning flashing lights, and at the same time, the driver and passengers on the car should also immediately move to a safe place and call the police for help.
