The skills of judging the distance between the left and right car bodies in narrow roads include hood judgment and right rearview mirror judgment.

1. hood judgment method

if you can see the hood when sitting in the car, the position of the left front corner of the hood perpendicular to the ground is the position where the left tire passes. However, when the driver looks at the left front corner of the hood, the distance and inclination will give you an illusion. The ground position seen by the driver through the hood is generally about 5 cm to the left of the position where the tire passes, so it is necessary to make an advance when observing. Look ahead through the left front corner of the hood about 3 cm to the right, which is the ground position where your left front wheel passes.

2. Right rearview mirror judgment method

The right rearview mirror judges the distance between the right car and the right shoulder. When the car body is in a straight line, observe the distance between the right car body and the right car or shoulder through the right rearview mirror. When the distance is 2 cm, it is 6 cm away from the right car body or shoulder.

Precautions for passing cars:

1. Pay attention to traffic command signals and traffic signs.

2. If you meet a car when the line of sight is unclear, you should reduce the speed in advance and turn on the low beam.

3. Don't use emergency braking, slam the accelerator and slam the steering wheel when passing.

4. avoid meeting at obstacles.

5. Avoid meeting at complex places such as narrow bridges, narrow roads, tunnels and sharp turns.

6. avoid driving at night without turning off the high beam.

7. When the car is driving on the road without the center line drawn, it should slow down on the right and be ready to stop at any time when it encounters the oncoming car overtaking in a short distance; If the other vehicle forcibly occupies the road, you should give up the lane as much as possible, or even stop politely.
