For those that do not quite get it or need special explanation.
28-3102. Exceptions to driver license classes; definitions
A. Notwithstanding section 28-3101, a person who operates an authorized emergency vehicle, a farm vehicle or a recreational vehicle may operate the vehicle with a class A, B, C, D or G license.
These are the class licenses ADOT requires by statute to drive any RV; hence ADOT RV class licenses and do not require any special endorsements.
This is from ADOT Commercial License information web site.
"Finally, successfully complete all applicable knowledge testing. Use the Commercial Driver License Manual as a study reference. The manual is available online or at any CDL office. For CDL offices outside the Phoenix and Tucson metro areas, an appointment is required to take the knowledge tests. You must pay for the class of license prior to taking the test. The fees are:
Class A or B permit, no endorsements: $25
Class C permit*: $12.50 (must have a P endorsement; HME not allowed on Class C permits)
Doubles/triples trailers endorsement: $10
Tank endorsement: $10
HME: $10
Motorcycle endorsement: $ 7
School bus** endorsement: No fee
Passenger endorsement: $10
*NOTE: A Class C CDL must include a Passenger or HazMat endorsement, although, only those applying for a Class C with a Passenger endorsement will be issued a permit. Class C permits can not be issued with a HazMat endorsement.
**NOTE: To add a passenger and/or school bus endorsement, you must obtain a CDL instruction permit with the passenger and/or school bus endorsement for the class of bus you intend to drive. Then, you must take CDL pre-trip, basic controls and road/skills tests in the appropriate class of bus/school bus.
For more information, please see our Permits FAQ."
Again for those needing special explanation. RV and passenger vehicles are different non interchangeable classifications of modes of transportation. Primary difference is one is a commercial vehicle one is a private vehicle. Another major division between the too one is a light class vehicle one is a use vehicle. As defined by 28-5601.
Your conclusion may differ....
I'm tired of beating this drum. If you disagree you disagree. I have better things to do.
