LANSING (AP) -- The Michigan Chamber of Commerce says it doesn't support a plan to turn solely to a ballot proposal to fix the state's billion-dollar road funding problem.

President and CEO Rich Studley says legislators should first act to put a plan in place before turning to voters. A proposal introduced in the Michigan Senate would amend the state constitution to raise the 6 percent sales tax to 8 percent and eliminate state fuel taxes.

Studley says the ballot proposal would delay action.

The chamber plans to push a plan funded primarily by user fees such as shifting the gas tax to a percentage of the wholesale price of fuel and raising vehicle registration fees.

Raising more money for roads is one of the business group's top priorities in 2013.
