What precautions should be taken when driving a dump semi-trailer in foggy weather?

1、 Control speed

The visibility is low in foggy weather, which greatly affects the driver's line of sight. Therefore, it is important to pay attention to controlling the speed. When the visibility is less than 500m and greater than 200m, the speed should be controlled below 80 kilometers per hour; When the visibility is less than 200m but greater than 100m, the speed should be controlled below 60 kilometers per hour; When the visibility is less than 100m but greater than 50m, the speed should be controlled below 40 kilometers per hour. If the fog is too thick and visibility is extremely low, it is best to drive the car to a safe roadside area or parking lot, and wait for the fog to dissipate or visibility to improve before continuing driving.

2、 Proper use of lights

Driving in foggy weather, lighting is very important. Before driving, the driver must check the installation of the car's lights in advance. When driving, pay attention to the following points: turn on the fog lights, tail lights, side lights, and low beam lights, fully utilize the lights, and further improve visibility.

3、 Clean View

When driving in foggy weather, the windshield is prone to condensation of water vapor, which can damage the driver's field of vision and make the lights emitted by oncoming vehicles appear particularly dazzling. Therefore, when driving in foggy weather, it is important to frequently use wipers to remove water vapor and ensure clear visibility.

4、 Use the horn frequently

In foggy weather, visibility is low and visibility is poor. Regularly honking the horn can serve as a reminder to pedestrians and other vehicles. When hearing the horn of another vehicle, one should immediately sound the horn to indicate the location of their own vehicle.
