MoDOT employee Michele Compton claims the device will only be triggered by speeders (however they choose to define that term), and that "The sound easily penetrates the windshield and well-insulated cab of a car, even overriding the vehicle's engine sounds and a radio turned up loud enough to jam to tunes at highway speeds."
Several people have brought up valid questions about the system's use — will it be able to tell if it's pointed at a car or a motorcycle, and compensate appropriately, or just blast the poor biker off the road? Aside from the obvious physical danger such a weapon would cause if deployed on a busy highway, there's also a more Orwellian component to be concerned with: Tasers were originally issued to police officers as less-than-lethal "deterrent" devices, and the scope of their use has crept into "compliance" territory. How long before the government is using the military grade weaponry such as the LRAD not to punish lawbreakers, but to control the populace in general?
Oh, wait, that already happened."
