Cutting U.S. Drunken-Driving Limit to .05 Not Backed by MADD

A National Transportation Safety Board recommendation for states to lower the definition of drunken driving to a blood-alcohol reading of no more than .05 percent failed to earn immediate support from groups the board considers allies.

Neither Mothers Against Drunk Driving nor the U.S. National Highway Traffic Safety Administration said they would push states to lower their drunken-driving thresholds from .08 to .05 percent after the NTSB announced its recommendation today.
