Semi-trailer square and side parking practice method

Chalk or slate should be equipped in the tool box in the car, in the event of an accident, it can be used to draw and fix the parking position and some marks on the ground.

1. Fixed motor vehicle parking position. Use chalk or stone pencil to draw a "T"-shaped line on the center of each wheel extension of the motor vehicle perpendicular to the ground.

2. Fixed non-motor vehicle parking position. After a non-motor vehicle has an accident, it usually falls to a certain side. You can draw a half arc line along the outer edge of the wheel, and at the same time use the words "front" and "rear" to mark the front of the arc line. wheel and rear wheel.

3. Fixed brake marks. Generally, at the starting point of a braking imprint, the starting point and width of the imprint can be outlined with a """-shaped line.

4. Fix scratches. When a non-motorized vehicle falls to the ground, it will generally leave strip marks on the ground between the pedal head or the wheel axle head and the ground. We only need to draw a strip line along the visible trace from the starting point to the end point.

5. Fix the position where the human body falls to the ground. In some accidents, the cyclist or pedestrian will lie on the ground after the accident. Before we organize rescue, it is best to outline the position of his head and feet. Here is a reminder: if the injury is more than minor, it is best not to "privately" and call the police immediately.
