The Arizona state Senate's Committee on Transportation recently approved SB 111 to increase motorists’ minimum liability coverage in a 6-1 vote.

Opponents of the change say drivers' insurance costs will increase, which has them questioning the decision.

“What you’ll accomplish is you will have increased premiums for the group that’s least able to buy more insurance,”  David Childres, a lobbyist for Property and Casualty Insurance Association, said.

Other advocates argue anything that increases costs will mean more people choosing to drive without insurance, despite laws making that illegal. 

Committee on Transportation panel chairman Bob Worsley (R-Mesa) said the change “would add only about $7 to $8 a month more to the average bill of those affected.”

Under Arizona law, motorists are required to have liability insurance. That includes $15,000 for possible injury, $10,000 for damaged property and $40,000 for injuries. If signed into law, they would change to $25,000 for injury, $25,000 for damages, and $50,000 for injuries.
