Missouri Department of Transportation to use LRAD Sound Cannons on Speeding Drivers
The Missouri Department of Transportation revealed two newly acquired LRAD sound cannons this week, which will reportedly be used to target vehicles that speed in work zones.
Coming in at $25,000 a piece, the Long-Range Acoustic Device, a sonic weapon best know for its use against protesters and insurgents in Afghanistan, will alert drivers to road conditions by shooting a loud verbal message through their windshields.
