Rep. Debbie Dingell (D., Mich.) has a plan to reduce drunk driving: Put breathalyzers in all vehicles.

Dingell announced Thursday she would introduce legislation to require car manufacturers to install breathalyzers, called ignition interlock devices, to ignition systems of all new cars. Before starting a car, drivers would have to self-submit to a breathalyzer test. If a driver's blood alcohol content is above the legal limit, the car will not start.
