Trucking
Trucking is currently the most popular mode of freight transportation within the country, with roughly 70 percent of all freight traveling over the road to reach its destination. Even when other modes of freight transportation are used, trucks are still usually needed to take the freight on the final leg of the journey – from the airport, dock, or railroad station to its final destination. Though truck drivers are restricted in the numbers of hours they can drive without taking a break, trucks as a whole aren’t as much a slave to schedules as other modes of transportation, making trucking a more flexible option in scheduling.
