In which year did the U.S. DOT take control of safety and regulations for trucking?

Answer: D — 1967

The U.S. Department of Transportation (DOT) took control of safety and regulations for trucking in 1967 with the establishment of the DOT itself. This marked a significant shift in the oversight and regulation of transportation in the United States. Prior to this, responsibility for trucking regulations was fragmented among various agencies and state authorities. The formation of the DOT allowed for a more coordinated and comprehensive approach to transportation safety, including the regulation of commercial vehicles and trucking operations. The DOT aimed to improve safety standards, efficiency, and performance in the trucking industry, thereby enhancing public safety on the nation's roads.
