If the bill is signed into law by July 15, the state would be eligible for $3 million in federal aid.
Under the measure, the legal limit for intoxication would be .08 percent. It's now .10 percent.
The Senate amended the bill slightly from a version the Assembly already approved. That means the Assembly has to agree with the changes before the bill can go to Gov. Doyle for his signature.
Doyle says he'll sign the bill.
Majority Leader Mary Panzer says some lawmakers weren't happy to vote for the bill. But she says they little choice because the state would lose federal money if it doesn't change the limit.
Besides the $3 million, the state would lose more than $150 million between 2004 and 2009 unless it goes from .10 to .08.
