When the visibility is below 100 meters, what is the maximum speed of driving a motor vehicle in expressway?

When a motor vehicle runs on the expressway and encounters meteorological conditions with visibility lower than 100 meters, the maximum speed shall not exceed 40 kilometers per hour. ..

When the vehicle owner is driving on expressway, if the visibility is lower than100m, the vehicle speed cannot exceed 40km/h. In addition, when the vehicle is driving on expressway, if it encounters fog, rain, snow, sand dust, hail and other environments with low visibility, the vehicle owner shall abide by the following provisions:

1 When the road visibility is less than 200m, the fog lights, low beam lights, position lights and front and rear position lights of the vehicle must be turned on, and the speed shall not exceed 60 km/h. ..

2. When the road visibility is lower than 100 meters, you must turn on the fog lights, low beam lights, position lights, front and rear position lights and hazard warning flashlights of the vehicle, and the speed shall not exceed 40km/h. ..

3. When the road visibility is less than 50 meters, you must turn on the fog lights, low beam lights, position lights, front and rear position lights and danger warning flashlights of the vehicle, and the speed shall not exceed 20 km/h. ..

Always pay attention to driving in rainy days.

1, keep your eyes open.

When driving on the road in rainy days, you should drive carefully and turn on the wiper in time. When the line of sight is extremely low in case of rainstorm, turn on the headlights, position lights and rear position lights, and drive the vehicle off the road or park it in a safe place.

2. Prevent the wheels from slipping.

When driving in the rain, "lubricant" is formed between the rain on the road surface and the tires, which makes the braking performance of the car worse and easy to slip. Therefore, the driver should hold the steering wheel with both hands in balance, keep driving in a straight line at a low speed, and when turning, he should step on the brakes to slow down to prevent the vehicle from slipping due to tire locking.

3. Prevent wading into the car.

When a car passes through a road with stagnant water, it should first stop to check the depth of the stagnant water. The water depth exceeds the exhaust pipe, which is easy to cause the car to stall. The water depth exceeds the bumper and it is easy to get into the water. Do not cross ditches and puddles at high speed. This will cause splash, increase the actual wading depth, and easily lead to engine water intake. Once the engine is turned off with water, do not start the vehicle again. You should park your car and wait for it to be towed away.

4. Pay attention to following the car

Especially don't get too close to the cart. First, it will block the line of sight; Second, the stagnant water car that the big car can pass may not pass, and the big car is easy to splash water waves, which makes the car suffer.

5, pay attention to observe pedestrians

Because pedestrians are holding umbrellas in the rain and cyclists are wearing ponchos, their vision, hearing and reaction are limited. Sometimes, in order to catch up with time, they will turn sharply, and when vehicles approach, they will often panic and slip, which will make drivers unprepared. In this case, drivers should slow down, avoid patiently, choose a safe place to park when necessary, and never compete with pedestrians and bicycles.
