INDIANAPOLIS (AP) — Indiana Bureau of Motor Vehicles officials say reforms to the poorly managed agency are underway, but will likely take several years to carryout.

Chief of staff Peter Lacy told a legislative committee Thursday that culture change at the agency will not come from “quick fixes.”

The BMV drew scrutiny after an independent audit released last spring found oversight lacking. The audit also revealed the agency overcharged motorists at least $60 million in fees in recent years.

Indianapolis Rep. Dan Forestal, a Democratic critic of the agency, says current management at the BMV has made significant progress. Forestal says many changes he asked for are being undertaken.

Lawmakers say they intend to rewrite complex and confusing portions of state law that governs the BMV during the upcoming session.
