What should I pay attention to when driving a motor vehicle on an icy road?

When driving a motor vehicle on an icy road, you should pay attention to: 1, the line of sight is blocked in rainy and snowy weather, so you must control the speed, slow down and keep a safe distance from the driving ahead; 2. The adhesion of tires on ice and snow roads is relatively small, so try to brake as little as possible when encountering ice and snow roads; 3. Don't turn the direction at will to avoid slipping or deviation. It is suggested that the car should be thoroughly inspected before driving on icy roads to ensure that the car is in good condition, especially the steering system and braking system should be effective and reliable. Check the tire pressure, take the lower limit of the specified value, and the left and right tire pressures are the same. At the same time, the car should be equipped with snow chains, which should be installed on the driving wheels, and the tightness of the snow chains should be consistent and symmetrical.
