MONTGOMERY, Ala. (AP) -- State Rep. Alvin Holmes was stopped for suspected drunken driving last week and was driven home by a law enforcement officer because of a state law that prevents legislators from being arrested for some offenses during sessions.

Holmes, D-Montgomery, was stopped shortly before midnight Wednesday night by a Montgomery County sheriff's deputy who said the lawmaker was weaving in and out of a lane on Interstate 65, said Sheriff D.T. Marshall.

Holmes said the accusations were "totally untrue." He said he was driving home from the Statehouse when his pickup truck started to overheat and the deputy pulled up behind him when he stopped to look for a flashlight.

The deputy, Gil Robinson, said when he approached Holmes, the representative's speech was slurred and the smell of alcohol was on his breath.

Robinson called a supervisor, who drove Holmes to his home, Marshall said.

The sheriff said Holmes was not arrested because state law prohibits the arrest of lawmakers during a legislative session, except for felonies, treason or breach of peace.
