FARGO (AP) - North Dakota ranks as the worst state in the nation when it comes to drunken driving.

Mothers Against Drunk Driving say 48 percent of the state's traffic fatalities last year involved intoxicated motorists.

There were 53 drunken driving deaths in North Dakota last year. That is about the same number of fatalities as Utah, which has four times the population and ranked best in the nation in terms of drunken driving deaths.

Mothers Against Drunk Driving blames the lack of a law requiring convicted drunken drivers to install devices in their cars to prevent them from starting if the drivers drink too much.

Eight states have such laws.
