The present invention relates to a highway speed limit monitoring device. The highway speed limit monitoring device is characterized in that an input port of a single-chip microcomputer is connected with a speed sensor, a timer and a GPS module separately, and an output port is connected with an alarm and a wireless signal transceiver separately; the wireless signal transceiver sends the vehicle overspeed data to a monitoring center server via a wireless network, and the monitoring center server sends the alarm information to the wireless signal transceivers of other vehicles via the wireless network and reminds via a vehicle-mounted alarm unit. The distances between the other vehicles receiving the alarm information and a monitored vehicle is not more than 5 kilometers, and the alarm information comprises the type, the license plate, the position and the current speed of the vehicle. The monitoring device of the present invention can send the vehicle overspeed information to a monitoring center, and the monitoring center also can send the alarm information to the vehicles around the overspeed vehicle timely, so that the surrounding vehicles can evade in advance to avoid the traffic accidents.
