Since the display is lit, the driver can quickly adjust the speed by instantly comparing the actual vehicle speed with the limit vehicle speed. As a result, safe vehicle speed traveling can be easily performed. Also, when turning a curve, if the running speed of the vehicle exceeds the limit vehicle speed, the controller activates the alarm means based on the detection signal of the vehicle speed sensor, so the driver knows that the running speed is excessively high and lowers the running speed. . As a result,
The driver's mental burden can be reduced.
