What significant improvement did the Commercial Motor Vehicle Safety Act of 1986 achieve?

The Commercial Motor Vehicle Safety Act of 1986 achieved a significant improvement by establishing nationwide minimum standards for Commercial Driver's License (CDL) testing. Before this act, there was considerable variability in licensing standards and testing procedures across different states, which could lead to unsafe driving practices and a lack of accountability amongst commercial drivers. By implementing uniform standards, the Act ensured that all drivers were assessed based on the same criteria, thereby enhancing the overall safety and reliability of commercial transportation. This standardization helped to ensure that drivers possess the necessary skills and knowledge to operate large vehicles safely, ultimately contributing to reduced accidents and improved road safety.
