摘要

The device has a sensor that indicates a target driving situation of a motor cycle. The sensor is mounted on a frame (3) of the motor cycle and on a field of vision of a driver`s position. A water level scale (5) is durably connected to the frame of the motor cycle. A glass tank of the water level scale is filled with the water and has a convex curved surface.
