The Alabama Department of Revenue will no longer ticket certain trucks with Oklahoma IRP registrations and will stop prosecuting existing tickets. Last year, the Alabama agency began ticketing Alabama-based truckers who registered their trucks in Oklahoma using trucking agents to register. Changes in Oklahoma’s system now require trucking companies to be physically located in the state. The Alabama Trucking Association and the American Trucking Associations sued over the decision but agreed to drop the lawsuit after state officials agreed to quit the ticketing campaign.
