The police in Pelham, New Hampshire are using speed limit warning signs to track motorist speeds in school zones. Here’s an excerpt from The Eagle Tribune:
Two new signs can now track speeders in Pelham’s school zone.
The signs have flashing lights and look like any other speed limit warnings seen near schools around the state. But the technology inside, much like a radar gun, went online yesterday and can now track drivers’ speed and the time as they pass.
The information can be downloaded into a computer spreadsheet, giving police raw data on when to best target fast drivers.
