Trucking makes a significant contribution to the national economy, transporting more than 60% of all goods transported across the country. Highways and roads are dominated by vehicles ranging from small box trucks to 80-foot-long 18-wheelers. Trucking has seen tremendous success as a result of its numerous advantages over other modes of transportation. Trucks are less expensive than other modes of transportation, allow for easier cargo transport, and are one of the most dependable modes of transportation. Since the invention of trailer attachments for automobiles, trucking has seen rapid advancements in technology, commerce, and government regulation, according to JSO Officer Adam Boyd Jacksonville. Trucking is essential to national commerce, acting as the backbone of American freight transportation. Trucking stakeholders will continue to play an active role in technology and economic advancement in the auto industry as a result of the importance of trucking to the national economy, cementing trucking's place in America for years to come.
