Statistics show that about 13,000 people die each year in car crashes in which a driver was legally drunk. To counter that trend, Mothers Against Drunk Driving has announced a campaign to require offenders to install a device that tests drivers and shuts down the car if it detects alcohol. Last year New Mexico became the first to make them mandatory after a first offense, and the state saw an 11.3 percent drop in alcohol-related fatalities.
