Generally a state will allow you to get your class A at age 18, but only to drive within the state with non-hazardous materials. At age 21 you should be eligible for interstate driving, but check with your state's licensing website as licensing varies from state to state.
Restrictions include: B - corrective lenses required D - Anatomical Donor M- Restricted to Class B and Class C Passenger vehicles (This restriction goes with a P - passenger endorsement on a class A CDL) N- Restricted to class C Passenger vehicles (This restriction goes with a P - passenger endorsement on a class A CDL)
Not sure what you mean, exactly. Class A is considered the "higher" classification, yes. If you have a Class A CDL, you can operate vehicles requiring that class of licence or any class below that. You could operate a vehicle requiring a Class B CDL, for example, but a driver with a Class B CDL wouldn't be permitted to operate a combination requiring a Class A CDL.
No.
.04, federally, for any CDL, regardless of endorsements. States can have tighter restrictions, including zero tolerance.
To operate ANY vehicle which requires a CDL of ANY class in ALL states (this is federal law - it doesn't vary by state), the driver must have, along with the appropriate class of CDL (A, B, C), a DOT Medical Card. However, this is assuming you're were referring to a Class C CDL - several states issue a non-CDL Class C licence.
CDL classes are A, B, and C - there is no Class D CDL.
Depends on which Class of CDL. A driver with a Class C CDL is not licensed on that vehicle. A driver with a Class B CDL can drive that combination only if the GVW of the trailer is less than 10,000 lbs. A driver with a Class A CDL can drive it.
Class 3 truck with a rollback body? No, it doesn't require a CDL.
Yes.
Depending on your state, there may not be any non-CDL Class A, B, and C licenses - CDLs are federally regulated... other license types are not. In states which do have that system, the weight rating equivalents are the same as they are for the corresponding class of CDL.
Mostly the same as any other licence, although CDLs do have a few unique ones, such as:No air brakes - if you don't complete both the written air brakes test and perform your road test in an air brake equipped vehicle, you'll get this one.No tractor-trailers - for a Class A CDL, you can do the road test in, say, an F650 and eight ton equipment trailer - it's a combination with a GCWR of more than 26,000 lbs. with a vehicle in tow with a GVWR in excess of 10,000 lbs. But they're not going to let you drive tractor-trailers if you do that.Intrastate only - issued to anyone who gets a CDL before the age of 21. Means they can only operate a CMV in the state which issued their licence.Bus restrictions - restricts the class of bus one may operate. The passenger endorsement requires its own road test. So, if you possess a Class A CDL, but your road test is done in a bus which only requires a Class C CDL, you'll be restricted to operating only buses which require a Class C CDL.
You can obtain a CDL class B license at your local DMV. To obtain a CDL class B license you are required to take several tests before obtaining your license.
