It is really simple....every time I have emailed penndot they have gotten back wih me pretty quickly... A class C license is not going to allow you to pull a trailer with a load. Your class of non-commercial license is based on weight... (d) Number and description of classes.--Licenses issued by the department shall be classified in the following manner: (1) Class A.--A Class A license shall be issued to those persons 18 years of age or older who have demonstrated their qualifications to operate any combination of vehicles with a gross vehicle weight rating of 26,001 pounds or more, provided the gross vehicle weight rating of the vehicle or vehicles being towed is in excess of 10,000 pounds. (i) The holder of a Class A license shall be deemed qualified to operate those vehicles for which a Class B or Class C license is issued. (ii) Where required under this title, appropriate endorsements must be obtained. (2) Class B.--A Class B license shall be issued to those persons 18 years of age or older who have demonstrated their qualifications to operate any single vehicle with a gross vehicle weight rating of 26,001 pounds or more or any such vehicle towing a vehicle having a gross vehicle weight rating of not more than 10,000 pounds. (i) The holder of a Class B license shall be deemed qualified to operate those vehicles for which a Class C license is issued. (ii) Where required under this title, appropriate endorsements must be obtained. (3) Class C.--A Class C license shall be issued to those persons 18 years of age or older, except as provided in section 1503 (relating to persons ineligible for licensing; license issuance to minors; junior driver's license), who have demonstrated their qualifications to operate any single vehicle, except those vehicles requiring a Class M qualification, with a gross vehicle weight rating of not more than 26,000 pounds or any combination of vehicles, except combination vehicles involving motorcycles, that does not meet the definition of either Class A or Class B of this section. An antiqe titled truck cannot be considered a commercial vehicle... Chapter 1603 of the Pennsylvania Vehicle Code defines a commercial motor vehicle as: "Commercial motor vehicle." A motor vehicle designed or used to transport passengers or property: (1) if the vehicle has a gross vehicle weight rating of 26,001 or more pounds or such lesser rating as the department shall adopt under the provisions of section 6103© (relating to promulgation of rules and regulations by department), as determined by Federal regulation and published by the department as a notice in the Pennsylvania Bulletin; (2) if the vehicle is designed to transport 16 or more passengers, including the driver; (3) if the vehicle is a school bus; or (4) if the vehicle is transporting hazardous materials and is required to be placarded in accordance with department regulations. The term does not include an antique or classic motor vehicle, or an implement of husbandry, or any motor home or recreational trailer operated solely for personal use, or motorized construction equipment, including, but not limited to, motorscrapers, backhoes, motorgraders, compactors, excavators, tractors, trenchers and bulldozers. I also have a letter in my truck from PennDot that says I do not need a class B or C license because my truck is titled and registered at 21000lbs...BUT, it is not completely 100% guaranteed legal because the state's definition of GVWR says specifically "original manufacturers gross vehicle weight rating". I am goint to have to change the weight listed on the title and registration to reflect the OEM weight of 50,000lbs, and the GCVWR of 80,0000lbs as originally manufactured. This will allow me to pull my camper and any trailer I choose. As for licensing,I was going to just upgrade my license to a class A, but the information on how to do this is sketchy, as I dont know what to study, and the air brake part is not defined for a non comercial class A, and I dont know anyone with a non-commercial class A to take to the test site, and there is no definition of the skills test for a non-commercial class A. From PennDOT... For the class A non-commercial license you must pass a written and road test. The information that you must study for the test is located in the Pennsylvania Driver’s Manual. When you go to take the road test you must have a driver with you that is 21 years of age or older with a class A non commercial license. You must bring your own vehicle that has a trailer and meets the weight requirements for the non-commercial class A license. So, I found a drivers school in State College that has testing authority and thier own trucks/trailers, will pay them for a couple hours of skills training and see if I can pass the drivers test in the same day... One more funny thing...the law says after I pass the written CDL test, I may begin "practicing" the skills portion...it does not say anything about being with a licensed driver!
