Harvest permits; extend repealer on provisions establishing maximum weight and approved routes of vehicles.

HB 953 extends the expiration date for Mississippi's weight and route approval rules that apply to harvest permit holders. These rules currently limit vehicle weights (up to 88,000 pounds for permitted vehicles) and require pre-approval for routes when transporting agricultural products like wood, sand, gravel, and crops. The bill prevents these specific regulations from automatically ending on their scheduled date, maintaining existing allowances for haulers. It directly affects commercial transporters with harvest permits who move qualifying materials within 100 miles of their origin.
