When taking the driver s license test, 30 cm away from the rearview mirror, how wide is the field of

When you take the driver's license test, you should be 30 centimeters away from the rearview mirror, and the field of vision in the rearview mirror is about two finger widths.

There is a small trick, we can look at the first vertex of the wiper counted on the right, and see that this point coincides with the solid line on the right side of the slope, so that we can keep it good, the car and the right line are 30 cm away from each other, and there is another point that in the examination room, there is generally a dotted line on the left, we use a protruding point on the left side of the car, and this dotted line to walk, so that we can also keep the car and the right line 30 cm away.

How to determine that you are 30 cm away from the rearview mirror when you take a driver's license:

Method 1: Look at the wiper protrusions.

From the cab, the wiper protrusion coincides with the right sideline, and the distance is about 30 centimeters.

Method 2: Look at the first third of the car.

Look at the front (right) thirds of the car, when it coincides with the right sideline, the distance is exactly 30 cm.

It can be difficult to find this third at first, as you don't necessarily see the same point every time. When practicing, students may wish to make a mark on the car first, and then remove the mark after getting used to it.

Method 3: Look at the right front door handle.

Observe the right front door handle in the right rearview mirror, if the right front door handle is tangent to the right sideline, the distance is just right; If you are too far away, you need to fine-tune the direction; If you get too close, you're in danger of crimping!

Subject 2: How wide is 30 cm in the rearview mirror? A lot of people can't grasp it well!

In the rearview mirror, the field of vision is about two finger widths apart.

When reversing into the garage, the distance between the body and the corner of the garage is from large to small. When 20 centimeters are reached, the car will return to the positive direction and maintain a distance of 20 centimeters until the garage corner disappears into the right rearview mirror.

30 cm has already reversed the rear of the car. (It needs to go through the process of hitting the right to return to the right and killing the right to the right, so it can be kept at 20 cm, but the final distance between the body and the edge of the library is generally between 20 and 30).

1. Before entering the curve, reduce the speed of the vehicle, drive into the S-shaped road in 1st or 2nd gear, keep the left and right distance between the vehicle and the right side of the road, and correct the direction appropriately (leaving enough distance for the left inner wheel difference).

2. Enter the first corner, the vehicle enters the curve along the right side of the road (about 1 meter from the edge of the left road), keeps a uniform low speed, plays the steering wheel to the left, and the vehicle changes from driving on the right side to driving on the left side.

3 out of 9 pass tips: drive in curves.

3. At the junction of the two corners, return to the steering wheel.

4. When entering the second corner, keep the left wheel of the vehicle on the edge of the road and correct the direction moderately.

5. When exiting the corner, turn the steering wheel and enter a straight line.

When taking the driver's license, many items have requirements that the distance between the body and the sideline shall not be greater than 30 cm, such as half-slope fixed-point parking and starting, right-angle turning, pulling over, etc., so how wide is 30 cm in the rearview mirror? Some people say that 30 centimeters is about two finger widths when viewed from the rearview mirror, is it true? Let's find out through **.

As shown in the figure, this is in the half-slope fixed-point parking and starting project, before driving to the half-slope fixed-point parking position, we should drive on the right side in advance, and keep the body and the right side line distance within 30 cm, the upper right corner of the ** is when the body and the sideline distance is within 30 cm of the position relationship, it does look about two fingers wide. However, half-slope fixed-point parking can not only look at 30 cm from the rearview mirror, but also from the front of the car, and this method is simpler and more direct, the rearview mirror only plays an auxiliary role in observation.

Now we come to the side parking, it is also required that the distance between the body and the sideline is within 30cm, and do not press the line, why do you have such a requirement? Because if you pull over improperly when parking, the tire and the curb rub and are squeezed, then the damage to the tire is very large, and even the tire will bulge or break. In addition, in some cities in China, in order to rectify the phenomenon of irregular parking, the right side of the vehicle is more than 30 cm away from the edge of the road for illegal parking penalties, and a fine of 50 yuan can be imposed.

As shown in the figure, when you see the distance between the right side of the body and the edge of the road from the rearview mirror, when the door handle just covers the curb, or just touches, the distance between the body and the side of the road is basically within 30cm, and the line is not pressed.

Finally, we come to the reversing link, when reversing, we have to observe the distance between the body and the corner of the garage through the right rearview mirror, and then judge when to correct.

As shown in the figure, observe the right rearview mirror, when you see that the rightmost line is exposed, the distance between the body and the library angle is less than 30cm, and if the distance is about 30cm, you don't need to correct it, continue to reverse. Here we see that 30 centimeters is about two finger widths apart.

A distance of 30cm from the rearview mirror is not always two fingers wide, and it may also be affected by the viewing angle, so the best way to do this is to practice more and find the most accurate method.

When taking the driver's license test, many items have requirements that the distance between the body and the sideline should not be greater than 30cm, such as stopping and starting at a fixed point on a half-slope, turning at right angles, and parking on the side of the road. So how wide is 30cm in the rearview mirror? Some people say that when viewed in the rearview mirror, 30cm is about two fingers wide.

Is this true? Let's take a look at the ** below.

As shown in the figure, this is a fixed-point parking in Banpo to start the project. Before driving to the fixed-point parking position of the half-slope, you should drive on the right side in advance and keep the distance between the body and the right side line within 30cm. **The upper right corner is the position relationship between the body and the sideline within 30cm.

It really looks like it's two fingers wide. However, the fixed-point parking of the half-slope can be seen not only from the rearview mirror 30cm, but also from the front of the car. And this method is more simple and straightforward, and the rearview mirror only plays a role in aiding observation.

Let's pull over. It is also required that the distance between the car body and the side line is within 30cm, and the line cannot be pressed. Why is there such a requirement?

If you pull over improperly when parking, the tires will rub against the side of the road and be squeezed, which will cause great damage to the tires and even cause the tires to bulge or be damaged. In addition, in order to rectify the phenomenon of non-standard parking on the roadside, some cities in China impose illegal parking penalties on vehicles with a distance of more than 30cm from the roadside on the right side of the body, and a maximum fine of 50 yuan can be imposed.

Finally, it came to the step of reversing and warehousing. When reversing, we look at the distance between the car and the corner of the garage through the right mirror, and then judge when to correct.

As shown in the picture, look at the right rearview mirror. When the rightmost line is exposed, turn half a circle when the distance between the car and the corner of the garage is less than 30cm. If the distance is about 30cm, it does not need to be corrected and continues to reverse.

Here, we see that the 30 centimeters here are also about two fingers wide.

A distance of 30cm from the rearview mirror is not always two finger widths and can also be affected by the viewing angle, so the best thing to do is to practice more and find the most accurate method.

How do you judge the distance between left and right when driving?

How to judge the distance of the car behind you by the rearview mirror?

30 cm from the rearview mirror, the field of vision in the rearview mirror is about two finger widths. We can look at one of the vertices of the first wiper counted on the right and see that this point coincides with the solid line on the right side of the slope, so that we can keep it good and the car is 30 cm away from the right line.

In the half-slope fixed-point parking and starting project, before driving to the half-slope fixed-point parking position, we should mention that the front is on the right, and keep the distance between the body and the right side line within 30 cm, but the half-slope fixed-point parking can not only look at 30 cm from the rearview mirror, but also from the front of the car, and this method is simpler and more direct, the rearview mirror only plays an auxiliary role in observation.

When pulling over, it is also required that the distance between the body and the sideline is within 30cm, and the line is not pressed, why should there be such a requirement? Because if you pull over improperly when parking, the tire and the curb rub against and be squeezed, then the damage to the tire is not always great, and even the tire will bulge or break. In addition, in some cities in China, in order to rectify the phenomenon of irregular parking on the side, the right side of the vehicle is more than 30 cm away from the edge of the road for illegal parking penalties, and a fine of 50 yuan can be imposed.
