Which Act was instrumental in regulating the trucking industry in the 1930s?

The Motor Carrier Act of 1935 played a critical role in regulating the trucking industry during the 1930s by establishing a framework for federal oversight of motor carriers. This Act was significant in that it helped to ensure safety standards, set rules for fair competition, and introduced measures aimed at preventing monopolistic practices within the trucking industry. Specifically, it required trucking companies to obtain operating authority from the Interstate Commerce Commission (ICC), which further standardized operations and efficiency within the industry.

This regulatory approach was necessary during a time when the trucking industry was experiencing rapid growth and changes. By centralizing regulations under this Act, the government aimed to promote reliability in service, establish fair rates, and enhance safety on the roads, which were all vital as more freight began to be transported by trucks instead of trains.

In contrast, the Surface Transportation Assistance Act, National Highway Act, and Freight Act of 1940 were either enacted later or addressed different aspects of transportation and infrastructure, rather than providing a foundational regulatory framework for the trucking industry during the 1930s.
