Inventors’ device blocks cell use around driver

Fred Wenz, a deliveryman for UPS for 23 years, has turned his frustration with drivers on cellphones into a safety business venture.

While on a run a few years ago, he came up with the idea for a device that blocks cell signals around a driver’s seat. It’s modeled on ignition locks that make a convicted drunken driver blow into an alcohol tester before the car will run.

"I witness it every day on the road, and I just thought, ‘There has to be a way that you can prevent this electronically,’ " says Wenz, 40.
