2. unilateral bridge: Left bridge: The left assembly line on the front hood of the car is aimed at the middle of the left bridge, so you can easily get on the left bridge. After the front wheel gets off, turn the steering wheel half a turn to the right until the left assembly line on the front hood of the car is aligned with the middle of the front white line (a right arrow) (if there is no white line in front, the blue sky examination room will definitely make a vertical mark on the ground). Make a circle to the left and immediately observe the right assembly line until the right line is aligned with the right side.
Supplement: If the assembly line on the right hood is inside the right line, it can be guaranteed not to cross the line. Another way is that car tires will leave white marks on the slopes of the blue sky. You can also use the left assembly line to track the middle printed matter. I can see it exactly.
The coach asked me to shoot the rearview mirror far beyond the line, and I did the same when I practiced before the exam. Before the exam, I found that the blue sky would draw a line on the wall on the right side of the parking lot, so I drove over and aimed at that line.
You can turn the steering wheel when the left wheel of the car leaves the bridge completely.
I wonder if I can open the door and see. Nobody asked this question at that time, and the coach didn't say anything.
