What are the dimensions of the motorcycle single-plank bridge?

[DeTanner]

Motorcycle single-plank bridge dimensions are as follows: Width: The single-plank width is 0.20m. Bridge height: The bridge height is the minimum ground clearance of the vehicle. The motorcycle bridge height is 5cm, small vehicle bridge height is 8cm, and other vehicle bridge height is 12cm. Lateral distance: The lateral distance between bridge A and B is the vehicle track width plus 1 meter. Longitudinal distance: The longitudinal distance between bridge A and B is 2 times the wheelbase for tractor-trailers, 3 times the wheelbase for small vehicles, and 2.5 times the wheelbase for other vehicles. Length: The plank length is 1.5 times the vehicle wheelbase. The single-plank bridge is one of the four items in the driver's license test (sometimes referred to as "9 choose 6" or "9 choose 4" in some regions), mainly assessing the driver's ability to control vehicle direction, accurately judge all wheel positions and driving trajectory, and master the technique of driving non-parallel vehicles.
