The braking distance in the rain becomes longer, can this method be used to cope?
Driving on rainy days is a big test for novices, because they have to face some special driving conditions in rainy days, such as slippery or muddy roads that make the wheels slip, and the vehicle stalls due to water intake from the exhaust pipe, but one of the common ones is that when the vehicle brakes, the braking distance will become longer. So what should we do when we encounter these?
When driving in the rain, the road area increases. If the drainage of the tire is not good, then the friction between the tire and the ground is not sufficient. When the car passes from the waterlogged road, it causes the direction to suddenly lose control, and the water will also resist the driving of the tire, causing slippage to the side of the water, which is prone to traffic accidents.
On dry roads, the speed increases, and the friction coefficient between the tire and the ground is almost unchanged, while on wet and slippery roads, the friction coefficient decreases sharply with the increase of speed. This is equivalent to the braking force also decreasing with the decrease of the coefficient of friction, so the braking distance increases accordingly. If you are not an experienced driver, it is difficult to have an accurate judgment of the braking distance on rainy days, so it is necessary to ensure that there is enough distance from the car in front of you, and the speed should not be too fast, which will reduce the accident rate.
In addition, when driving on rainy days, you should also pay attention not to hastily reduce the tire pressure. There may be some drivers who think they are experienced, before the rainy season, will lower the tire pressure of the tire, so that the tire flattened, to increase the contact area with the ground, using this method to cope with the brake distance edge length and prevent side slippage. This method is not advisable, because the tire contact area increases, then the pressure on the ground unit area becomes smaller, the force when braking will be reduced, and the rainwater in the tire groove cannot be discharged in time, resulting in an increase in the distance when braking.
