Most states will place an X endorsement on the licence of a driver if they have N and H endorsements - X is a combination of hazmat and tanker.
You can have a CDL (Commercial Driver's License) without a Hazardous Materials Endorsement, but you have not have the HazMat Endorsement without a CDL.
Yes. A CDL doesn't nullify the requirement for a motorcycle endorsement.
K is not an endorsement it is a restriction for intrastate only. That means a CDL with a K restriction is only valid in the issuing state only.
The X endorsement is a combination of two endorsements - Hazmat (H) and tanker (K).
An "H" endorsement on a Commercial Drivers License "CDL" means that a driver is qualified to transport hazerdous materials.
A felony conviction will cause your hazmat endorsement to be rejected nationwide.
When I had my own business, they needed a Class A CDL and hazmat endorsement.
Yes, that's part of your CDL physical.
Yes. The vehicle would require a Class C CDL with the Passenger endorsement.
You may only have one license. If you have a Class A CDL, you can operate a vehicle requiring a Class B or Class C CDL, so long as you have any endorsements necessary for the vehicle type (e.g., tank endorsement for tank vehicles, passenger endorsement for passenger vehicles, hazmat endorsement for vehicles hauling hazardous materials, etc.).
HME won't be seen on a CDL - the endorsement for hazmat on a CDL is H, or X if it's in conjunction with a tanker endorsement. HME is often used as a shortened form of "hazmat (or 'hazardous materials') endorsement".
You MUST have a CDL in order to get a hazmat endorsement.
