Rear projection of load
The load upon the rear vehicle of a combination of vehicles transporting forest or agricultural products in their natural state must not project more than 28 feet beyond the rear axle of the vehicle.
If projecting more than 28 feet beyond the rear axle and, due to the end use for which they are intended (such as tall utility poles or light poles or the like), then this special circumstance may be considered good cause for obtaining a permit pursuant to Miss. Code Ann. § 63-5-51 before operation.
