Speed Monitor III
The only speed sign that reads only the
speed of approaching vehicles.

No speed control sign outperforms the Speed Monitor III. The speed Monitor III has a “super-bright” LED display designed to give many years of maintenance free service, and which is much more visible than mechanical flip signs. The Speed Monitor III includes MPH’s exclusive and patented Approach-Only Sensor™, which only measures the speed of vehicles approaching it. This means that the Speed Monitor won’t pick up vehicles moving away from it, no matter how large or close they are. The Speed Monitor III is enclosed in a weatherproof, Lexan® housing. The Speed Monitor III has digits that are 12 inches tall providing visibility for over 500 ft. (150 m).

The Speed Monitor III is our most popular roadside Speed Display because of the Approach Only Sensor capability.
