INDIANAPOLIS (AP) — A plan overhauling Indiana’s specialty auto license plate system and requiring all groups with plates to sell 500 a year has been signed into law by Gov. Mike Pence.

The bill approved by lawmakers creates an eight-member bipartisan commission to review requests from nonprofit groups seeking specialty plates. The panel will check financial reports at least once a decade on how the groups are spending their plate proceeds.

The bill sets a limit of 150 specialty plates. A legislative report shows that 17 of the 92 specialty plates sold during the past two years fell short of selling the minimum 500 plates a year.

Supporters say the new rules are meant to keep a handle on the number of specialty plates and ensure the money is spent appropriately.
