Guidance for § 390.9: State and local laws, effect on.

Question 1: If an interstate driver gets stopped by a State enforcement officer for an inspection, would the inspecting officer be enforcing the Federal regulations or State regulations?

Guidance: A State enforcement officer can only enforce State laws. However, under the Motor Carrier Safety Assistance Pro gram, quite often State laws are the same as or similar to the FMCSRs.
