Wisconsin Gov. Jim Doyle has signed a bill that stiffens the state's drunken driving laws, despite questions about whether it does too little.
The law signed Tuesday makes a fourth offense drunken driving a felony if it occurs within five years of the previous offense. A first offense will be a misdemeanor if someone younger than 16 is in the car. Repeat offenders and first-timers with high blood alcohol contents must get ignition interlocks.
The new penalties take effect July 1.
But two of the toughest changes advocates wanted weren't included: making all first offenses a crime and legalizing roadside sobriety checkpoints.
Federal data shows about 41 percent of Wisconsin's traffic deaths in 2008 were alcohol-related. The national average was 37 percent.
