Agricultural and Forestry Hauling Efficiency ActThis bill allows Virginia to increase the vehicle weight limit for covered agricultural vehicles traveling on interstate highways to 90,000 pounds. Specifically, Virginia may provide a special permit for these covered agricultural vehicles to operate on interstate highways in Virginia.The term covered agricultural vehicle means a vehicle that is transporting (1) unprocessed agricultural crops used for food, feed, or fiber; or (2) raw or unfinished forest products, including logs, pulpwood, rough-sawn green lumber, biomass, or wood chips.Under current law, there is an 80,000 pound overall gross vehicle weight limit for interstate highways, with exceptions. Virginia allows certain agricultural vehicles that do not exceed 90,000 pounds to travel on Virginia highways that are not part of the interstate highway system.
