Subject 1: Summarizing and sorting out the driving problems in expressway.

Subject 1: expressway's driving speed: 60- 120 (enter the high-speed acceleration lane and lift it as soon as possible if it exceeds 60 kilometers), and the theoretical test expressway's driving speed limit: |120 ~100 | 100 ~ 60 |, two lanes: left/kloc. Right: 60 ~100 |120 ~10 |100 ~ 90 | 60 |, three lanes: left 10 ~ 65438+ four lanes and above are similar to three lanes: the most

If the speed of motor vehicles in expressway is greater than 100, it shall keep a distance of more than 100 meters from vehicles in the same lane; When the vehicle speed is less than 100, the minimum safe distance shall not be less than 50m.

In bad weather, such as rain/fog/dust/hail, the problem of vehicle speed and distance with different visibility;

1, when the visibility is less than 200m, turn on the fog lights, low beam lights, position lights and front and rear position lights at a speed of 60km/h and keep the distance above 100m;

2. When the visibility is less than 100 meters, turn on fog lights, low beam lights, position lights, front and rear position lights and hazard warning flashlights, and the speed shall not exceed 40 kilometers per hour, and keep a distance of more than 50 meters from the vehicle in front of the same lane;

3. When the visibility is less than 50 meters, turn on fog lights, low beam lights, position lights, front and rear position lights and hazard warning flashlights, and the speed shall not exceed 20 kilometers per hour, and leave expressway from the nearest exit as soon as possible.

Shorthand of expressway's driving problem in theoretical examination: three numbers -26 1,145,520 (200m, speed 60, distance100; 100m, speed 40, distance 50; 50 meters, speed 20, distance 0 means leaving as soon as possible)

Contrast: On general roads, during the day and night, when the car breaks down on the road and it is difficult to move, turn on the danger warning flash and set up a warning sign 50- 100 meters behind the car; On the expressway, set a warning sign behind the car at150m (note: don't set it in high-speed fog, there is a way to judge).

On general roads, no matter what the weather is like, the visibility is less than 50 meters, and the driving test speed in expressway is 30 kilometers per hour. Turn around and cross the railway crossing. Everything is 30. Others, such as driving test in expressway in rainy days, the vertical safety distance should be 1.5 times of the usual; In ice and snow weather, the longitudinal safety distance should be 3 times of the usual (applicable to expressway and general roads).
