When driving on the highway, you should pay attention to the following items:

1. When entering the main lane from the ramp, when there is an acceleration lane at the entrance, the speed should be increased to a certain speed through the acceleration lane. When merging lines, vehicles driving in the main lane should not be hindered.

2. It is necessary to strictly distinguish the functions of lanes and drive in different lanes. In general, you should take the main lane, and only use the overtaking lane when overtaking to ensure smooth traffic.

3. Obey the speed limit, speeding is prone to accidents. Too low a speed will hinder the normal driving of other vehicles. When driving in rain and snow, you should slow down.

4. When driving, always pay attention to the signs and markings on the side of the road and above the road, drive to the right appropriately, avoid rolling over the right lane divider, and make it convenient for the rear car to overtake with enough lateral distance.

5, should keep the longitudinal workshop distance. Under normal circumstances, when the road surface is dry and the braking is good, the workshop spacing should not be less than the vehicle speed.

6. Please don't reverse the car, turn around, cross the main lane, and don't exceed the middle lane.

7. Do not interfere with the tasks of fire fighting, first aid, public security and first aid vehicles.

When you need to brake, it is best to brake several times more, and don't step on it to prevent the vehicle from running off.

9. When overtaking, estimate the distance and speed of both sides. When the situation is normal, you should sound the horn and turn on the left turn signal, overtake the front car from the overtaking lane, and you are not allowed to overtake from the right side.

10, the change of light entering and leaving the tunnel will affect vision, so it is necessary to slow down the speed appropriately to adapt to the change of light and shade.

1 1. When driving out of the expressway, pay attention to the sign at the intersection, divert the car from the main lane to the deceleration lane to slow down, and enter the general expressway via the ramp.
