What are the key points of special weather operation during driving?

On the way to go on road trip, you may encounter sudden weather changes, especially scenic spots, such as fog or sudden thunderstorms in the morning. What should I do under these circumstances?

(1) Sandstorm Weather In sandstorm weather, small cars should pay special attention to the crosswind generated by the driving of large trucks. The driver can turn the steering wheel slightly to correct the direction of the car, and don't slam the steering wheel.

(2) When there is fog, try to drive at a low speed on the ordinary highway, and then drive on the highway after the fog clears. If there is sudden fog when driving on the expressway, you should immediately drive to the nearest service area or parking lot to temporarily shelter from the rain, or drive to the shoulder or emergency parking zone to stop, and turn on the width light, tail light, rear fog light and danger warning light. The key to driving is to start slowly, and avoid sudden acceleration, sudden braking or slamming the steering wheel. When braking, try to use the brakes instead of stepping on them. It is also necessary to demist in time. You can use the demister of the air conditioner to remove fog quickly or open a crack in the window.

(3) It is not advisable to drive too hard after snow. Brake continuously on Xueping Road, and shift gear on downhill road (fast downshift). It is best not to stop on uphill road in case it is impossible to start. Normal movement can be properly shifted (low speed and high slope) to increase tire grip. Control the speed, especially when turning or going downhill, be sure to control the speed within the range where you can stop at any time. When you need to accelerate or decelerate, you should slowly step on or release the accelerator. According to the terrain, speed, loading capacity, etc. Keep a distance from the car in front. Try to avoid overtaking. If you need to overtake under special circumstances, you must choose a spacious, flat road section with less ice and snow. When you need to turn, you must reduce the speed as much as possible in advance, increase the turning radius as much as possible and turn the steering wheel slowly to reduce the centrifugal force when turning. You must not make sharp turns or sharp turns to prevent sideslip and sideslip.

(4) Driving in rainy days, flashing when you see stagnant water in rainy days, or braking immediately to slow down, is a common problem of ordinary people. In fact, the water depth of about 15 cm will have no effect on the car. Just don't increase the throttle to flush, so as not to cause water in the brakes and electrical components; It is also necessary to control the speed, especially on the expressway, where the road surface is in poor condition and there is water, otherwise the vehicle will drift easily, leading to accidents. It should also be noted that when the vehicle passes through stagnant water, the braking system may be temporarily weakened and the braking distance will be lengthened, so it is best to keep a longer safe distance when driving in rainy days.

(5) When encountering lightning, don't get off in a hurry to find a place to hide. Because if lightning strikes the car, the current will be conducted to the ground through the surface of the car body, and it will not be felt at all in the car, but it will be very safe. So when it thunders, all you have to do is close the window tightly, and the antenna of the radio must be put away, because the antenna acts as a lightning rod and will absorb lightning.
