WALTHAM, Mass. -- An alcohol-detection prototype that uses automatic sensors to instantly gauge a driver's fitness to be on the road has the potential to save thousands of lives, but could be as long as a decade away from everyday use in cars, federal officials and researchers said Friday.
U.S. Transportation Secretary Ray LaHood visited QinetiQ North America, a Waltham, Mass.-based research and development facility, for the first public demonstration of systems that could measure whether a motorist has a blood alcohol content at or above the legal limit of .08 and -- if so -- prevent the vehicle from starting.
The technology is being designed as unobtrusive, unlike current alcohol ignition interlock systems often mandated by judges for convicted drunken drivers. Those require operators to blow into a breath-testing device before the car can operate.
