It depends. If it's a vehicle of more than 10,000 lbs. GVWR being used in interstate commerce, yes. If it's a vehicle over 26,000 lbs. GVWR, yes. If it's a vehicle under 26,000 lbs. GVWR but it either a bus designed to transport more than 15 persons or is carrying a hazmat load which needs to be placarded, yes. In the case of the latter three, you also need a CDL.
10,000 lbs. GVWR and up in a commercial use vehicle, and the answer is yes.
No.
If the commercial vehicle requires a CDL to drive it, you do.
If the Gross Vehicle Weight Rating - not the actual laden weight at the time - is under 26,000 lbs., then no. You will, however, need a current and valid DOT medical card.
Yes anytime your driving a vehicle that requires a health card you need to have your health card with you
If the GVW is more than 10,000 lbs, yes.
If it requires a CDL, then yes - that's federal law.
No, you do not need a green card to drive in France.
The air brakes are irrelevant. And you'd need a medical card in that instance if you were doing interstate operations, but not intrastate operations.
They would need a medical card if the Gross Vehicle Weight Rating was over 10,000 lbs, AND it was being used for commercial purposes, AND it was being operated across state lanes.Beyond that point, once you get into weight ratings requiring a CDL, then you'd need a medical card at all times.
You're required to have a current medical card on your person at all time when you're driving a vehicle which requires a CDL. In any state. That's federal law.
You need a license to drive a tow truck in Michigan. You need a license to operate any vehicle on public roads.
