Do state laws govern how commercial vehicles operate at railroad crossings?

State laws do not govern how commercial vehicles operate at railroad crossings because federal regulations, particularly those enforced by the Federal Motor Carrier Safety Administration (FMCSA), take precedence in this area. These federal regulations establish strict safety standards for commercial vehicle operations, including protocols for approaching and crossing railroad tracks.

While states can implement additional rules or guidelines that may complement federal standards, they cannot contradict or carve out authority away from these federal regulations when it comes to the essential safety measures required at railroad crossings. The focus on uniformity ensures that all drivers, whether operating commercial or personal vehicles, follow the same safety protocols, thus enhancing safety at these critical intersections.

It's important to note that some states may provide specific supplemental guidelines to support safety initiatives, but in terms of regulatory authority, the federal rules hold sway over state laws in this domain.
