How does state law apply to CMV operations during interstate travel?

The correct answer is that the law of the state the vehicle is in takes precedence. When operating a commercial motor vehicle (CMV) during interstate travel, drivers must adhere to the laws of the state in which they are currently located. Each state has its own regulations regarding traffic laws, vehicle operation, and safety requirements. This means that as a driver crosses state lines, they must comply with the regulations of the state they are in at that moment.

This understanding is essential for maintaining safety and legality while operating a CMV, as different states may have varying rules regarding speed limits, load restrictions, and other operational standards. It fosters accountability and ensures that drivers respect the differences in traffic laws across state borders.

In contrast, while federal laws do provide a framework for interstate commercial vehicle operations, they do not nullify state laws. Therefore, time spent in each state necessitates adherence to local regulations. Recognizing that state laws take precedence while in that jurisdiction is crucial for any CMV operator.
