What if the driver never leaves your property? Is the driver subject to DOT testing?

A motor carrier will need to look at its operation to see if its parking lot or yard meets the definition of “highway” in 390.5: “any road, street, or way, whether on public or private property, open to public travel.” “Open to public travel” in general terms means that the road is open to the general public for use without restrictive gates and prohibitive signs. Based on this, a mechanic, dispatcher, or supervisor who just moves a CMV out of a garage to a parking space could possibly be subject to DOT testing.
