石子路面摩擦力很小,汽车在上面行驶,遇到意外情况需要紧急刹车时,很容易发生侧滑,非常危险。为此,我们在石子路面上行车时,一定要注意慢行,集中精力,谨慎驾驶,尽量在公路中央行驶,缓慢加油,平稳加速,遇到会车、转弯和需要刹车时,更要注意进一步降低速度,多使用点刹车。特别需要注意的是,汽车转弯时,必须把车速降低到车体不倾斜的程度才能安全转弯。为了判断弯曲度 Gravel road friction is very small, cars driving in the above, in case of unexpected emergency braking needs, it is prone to skidding, very dangerous. Therefore, when we are driving on the stone pavement, we must pay attention to slow walking, concentrate on and drive with caution. Try to drive in the center of the highway, slowly refuel, smooth and accelerate, and pay more attention to meeting cars, turning and braking required Reduce speed, use more points brake. In particular, it is important to note that when turning a car, it is necessary to reduce the speed of the car to such an extent that the car body does not incline to make a safe turn. In order to determine the curvature
