What do you mean, go, sand, slow water?

You need to pass as soon as possible when you meet the sand road, and you need to pass slowly when you meet the waterway. This is the law summed up by the driver's long-term experience when the vehicle is driving on the road.

1, sandy pavement, due to the lack of hardness of the sand, if the vehicle encounters potholes, especially the road with loose soil, it is easy for the vehicle to get stuck in the sand because of the weight of the vehicle body, so the driver sums up experience and passes quickly, and the inertia of the vehicle ensures that it will not get stuck in the sand.

2. On the road with accumulated water, because we can't see the underwater road, and if the vehicle passes through the accumulated water road quickly, it will make the water hide from the front of the vehicle, which can't guarantee that the vehicle won't fall into or hit the underwater obstacle, and it may also make the water enter the engine and cause the flameout, so the driver concludes that the accumulated water road needs to pass slowly.

Matters needing attention when driving on roads with accumulated water in the extended data:

The first thing is to pay attention to the depth of water accumulation and braking to prevent engine flameout and brake failure. On rainy days, there is water on the road, so be sure to pay attention to the water depth. If the water depth exceeds the height of the exhaust pipe, the vehicle will easily stall, so try to take the shallow water route.

If you don't go through the road with deep water, the water depth is more than half the height of the tire, the driver can wade carefully; Pay attention to the foot brake and hand brake after immersion, because the braking efficiency may be weakened after immersion. If the proven water depth exceeds the whole tire, it is not suitable for wading, otherwise the engine of the vehicle will easily stall. At this time, you must detour or wait until the water depth becomes smaller before wading through.

The second is to understand the road conditions of the stagnant water section. On rainy days, the water on the road surface is muddy, but if it is not a fast-flowing water surface, we can still judge the general situation of the bottom of the water by observation. Generally, there are obstacles such as big stones in places where there are waves and eddies, while places where the water surface is calm are generally deep, the water surface is open, and even there are broken waves. Generally, they are shallow layers with broken stones at the bottom, which is an ideal place for driving through.

In addition, it should be noted that during or after the rainstorm, the genes of shoulder and pavement are soaked and washed by rain, which may soften or even collapse. At this time, you must be careful to drive and wade to avoid rollover and traffic accidents.
