Is the DOT regulated by OSHA?

No, the United States Department of Transportation (DOT) is not regulated by the Occupational Safety and Health Administration (OSHA). While both agencies are part of the United States federal government, they have different areas of jurisdiction and responsibility. However, according to OSHA, "The DOT regulation preempts enforcement, and DOT has jurisdiction. However, if the vehicle is an intrastate truck, OSHA has jurisdiction. Only another Federal agency may preempt OSHA's jurisdiction."

The DOT regulates transportation-related activities, including moving goods and people by truck, train, airplane, and other means. Its regulations cover a range of issues related to transportation safety, including drug and alcohol testing, security, and environmental concerns. At the same time, OSHA ensures safe and healthy working conditions for employees in all industries. Its regulations cover many workplace safety issues, such as using hazardous materials, equipment safety, and workplace ergonomics.

However, there are some areas where the regulations of the DOT and OSHA may overlap. For example, both agencies have rules related to handling hazardous materials and work together to ensure that these regulations are consistent and complementary.

While the DOT and OSHA are federal agencies that regulate different safety aspects, they have other areas of responsibility, and they are not directly controlled by one another.
