Why is there a traffic jam when it rains?

In rainy days, traffic lights may be abnormal, and the main reason for this phenomenon is the circuit. In rainy days, the wind is strong and it is easy to disconnect, which leads to traffic lights failure and traffic jams.

2, water pavement influence pass rate:

It is necessary to measure the water depth when passing through the waterlogged road surface. For some careful drivers, the pressure is relatively high, and they will be more cautious when passing through wading sections, which will limit the speed and lead to traffic jams.

When passing through the stagnant water road surface, you can observe the traffic situation of the preceding vehicle and judge the water depth. When passing, it is necessary to control the speed and pass smoothly, and try not to shift gears when wading.

3. There are more novice drivers:

There are many people taking taxis when it rains, so it is difficult to take taxis. Many novice drivers will drive on the road. Because of their poor driving skills and unclear vision, they will drive slowly and even have traffic accidents, which is also one of the reasons for traffic jams.
