MADISON, Wis. -- A provision requiring drivers to have auto liability insurance was signed into law on Monday as part the state budget.

By July 2010, every driver will be legally required to carry auto insurance. The amount of liability insurance also goes up in January.

Critics say the move will raise rates for everyone, but those who support it say it's a move toward more consumer protection.

"It really is more updating some of the limits you have, what are called financial responsibility limits, that had not been changed in 25 years," said Sean Dilweg, the state insurance commissioner. "And those are being increased two-fold, which really, if you think of medical costs, really falls in line with what people face," said Dilweg.

After July, New Hampshire will be the only state in the country that doesn't require drivers to be insured.
