High speed driving instructions

1, pay attention to the weather forecast and traffic broadcast information, and check the technical condition of the vehicle you are driving. Whether the acceleration performance is good, whether the steering, braking, tires, lighting, rearview mirror and other equipment of the vehicle are normal.

2. When the vehicle is driving normally on the expressway, the minimum speed shall not be lower than 60km and the maximum speed shall not be higher than 120km. However, if the speed limit traffic signs are inconsistent with the above provisions, the provisions of traffic signs or markings shall be observed.

3. Avoid slamming the steering wheel at high speed. In case of strong wind, the steering wheel is difficult to control, slow down and drive carefully. Especially at the tunnel exit and the excavated mountain road, pay attention to the crosswind that causes the steering wheel to deflect.
