Have you ever wondered how some GPS units can warn you of traffic? Theres your answer. It is the "detectors" that detect stopped or slowed traffic.

And you know this how, might we get a bit more info?
Those are Monger monitors.
Detector is approx. 13”4”x4”, white in color, single cord attached to rear from small solar panel, front has an opaque lens. Unit may be pointed in either travel direction on either side of road with mostly inconsistent spacing, though usually more than 3 miles. If you are traveling the Interstates today, see if you spot any.

I gotta give it to ya Phil...you have developed a sense of humor since moving to Landstar. You should do a "today, I learned" blog on that
It's not often seen here, but Phil has shown a sharp sense of humor since way before switching to Landstar.
