your company needs to contact the IRP jurisdiction that the cab card is registered in. Have them up the registered weight. If you are operating on a commercial tag then this can be done from your local tag office. In Oklahoma you can purchase a trip permit for temporary vehicle registration that will automatically register you for the max(90,000lbs) for 72 hrs. Interstate is still restricted to 80k unless you have a permitted non seperable load. A trip permit is 12 dollars.
