A coalition of opponents of drunk driving, supported by the O'Malley administration, will hold a news conference Wednesday to drum up support for a bill that would require ignition interlock devices for all convicted drunk drivers.

Mothers Against Drunk Driving and the Maryland Highway Safety Foundation, two of the organizations that have put the ambitiously named Eliminate Drunk Driving Act at the top of their legislative agendas, will be represented, along with lead sponsors Sen. Jamie Raskin and Del. Benjamin F. Kramer, both Montgomery County Democrats. AAA Mid-Atlantic is also on board for the noon news conference at Lawyers Mall in Annapolis.

Motor Vehicle Administrator John Kuo will represent the  administration. Gov. Martin O'Malley has said he would sign the bill if it reaches his desk. The legislation faces strong opposition from the alcoholic beverage industry, which contends the interlock devices -- which prevent a vehicle from being started if its driver has been drinking alcohol -- are more appropriate for repeat offenders.
