According to a recent article on the website carinsurance.com, Mothers Against Drunk Driving (MADD) will be making a push across the country for states to enact laws requiring convicted drunk drivers to install ignition interlock devices in their cars. Only 14 states — Alaska, Arizona, Arkansas, Connecticut, Hawaii, Illinois, Kansas, Louisiana, Nebraska, New Mexico, New York, Oregon, Utah and Washington – currently require ignition interlock devices for every convicted drunk driver. In Colorado, a person is required to install the interlock if they are convicted of Driving Under the Influence (DUI), have multiple drinking and driving convictions, or were revoked for having a BAC above .08.

New Mexico has seen a 35% reduction in drunk-driving fatalities since it passed its ignition interlock law. Drunk driving deaths have been reduced by 46% in Arizona since 2007. A study by the Centers for Disease Control and Prevention estimated that the interlock reduced second offense rates by 67%.

Update:   A bill has been introduced in the US House of Representatives to offer additional highway funds to states that require ignition interlock devices for DUI offenders.
