HELENA, Mont. - Some Montana motorists, the joke goes, measure distances driven by how many beers they can down along the way. But the long-cherished right to have a cold one behind the wheel is about to end.
State lawmakers passed an open-container ban Friday that makes Montana one of the last states to outlaw drinking while driving.
The Montana House approved the bill 76-21 and sent it to Gov. Brian Schweitzer, who has said he will sign it. It takes effect Oct. 1.
The delay is designed to let Montanans get used to the prohibition, which until now had been found only in cities and towns, not out on the open highway.
