BATON ROUGE - Another round of 700,000 collection letters have gone out to Louisiana drivers, notifying them they have 30 days to pay fines for lapsed insurance coverage before their cases get turned over to a state collection agency.

In an update Monday, the Office of Motor Vehicles said 55,000 cases of drivers flagged for violating state insurance coverage requirements have been cleared. In one-third of those resolved cases, the agency said, drivers didn't pay anything after showing they shouldn't have been fined.

The OMV received complaints after mailing 1.1 million collection letters to drivers last month. Some drivers said they were being improperly accused of lapsed insurance.

The agency added phone lines and lengthened hours to help people clear improper penalties. More information for drivers who received collection letters is at ExpressLane.org.
