What are the requirements for the single-plank bridge driving test?

[Barnes]

The single-plank bridge driving test requires the driver to maneuver the vehicle so that the left and right wheels pass over two pillow-shaped protrusions with a slope of less than 7% consecutively. This mainly assesses the driver's ability to control the position of the vehicle's wheels and the driving trajectory. In actual driving, it is difficult to master the position and trajectory of the wheels, requiring prolonged practice. Additional information: The position of the right bridge corresponds to the usual trajectory of the right front tire. To correctly pass the bridge, it is essential to understand the width of the car and the positional relationship between the driver's seat and the right tire. When parking, go to the front of the car and extend a line from the position of the right front wheel to the front of the car. Then, draw another extended line in front of the driver's seat. Return to the driver's seat and carefully observe the positional sensation of these two lines from the driving position.
