What drivers are covered by the federal rule? Drivers who operate a CMV intrastate or interstate? Drivers who hold a CDL? Or is it operation of all CMVs?

The rule covers both drivers of CMVs in interstate and intrastate commerce (vehicles with a GVWR or CGVWR greater than 10,000 pounds). Also drivers who operate a vehicle transporting a quantity of hazardous materials requiring placarding under 49 CFR Part 172 or any quantity of a material listed as a select agent or toxin in 42 CFR part 73. If a CMV driver is employed by the state or a political subdivision of the state (e.g., county, city, township, etc.), FMCSA safety regulations (part 382, 391, 392, 393) apply, even if the driver is only engaged in intrastate transportation.
