A lot may be familiar with the term CDL, or commercial driver’s license but may not be fully aware of its purpose or perhaps the opportunities that come with it. The ability to operate larger commercial vehicles can only be granted to those who can pass the CDL exam. These PA CDL endorsements grant the applicants additional driving privileges without the need to apply for multiple license types. The majority would opt to apply for a commercial driver’s license which would not deem effective especially to those who have gotten a hold of class C licenses or motorcycle endorsement since they can be added to any regular driver’s license.
PA CDL Endorsements
Even though some states require more restrictive classifications of licenses or additional endorsements, they are acceptable as long as they. Are explained thoroughly on the licensed document. The following are Federal endorsements: H, N, P, S, T, and X even though only P, S, and N endorsements are recognized by the Illinois CLP. With that said, Illinois holders with “P” endorsement are not allowed to operate a CMV that transports passengers, “S” endorsement Illinois holders are prohibited from school bus operation, and “N” endorsement Tennessee holders can only operate empty tank vehicles and are banned from driving tanks previously carrying hazardous materials.
- H (Knowledge test only) – hazardous materials
- N (Knowledge test only) – tank vehicle

- S (Knowledge and skills test) – school bus operation

This can only be done once you have completed all tests and medical forms after you can pay the fee, submit your thumbprint, and lastly provide any other additional required by the assigned TSA agent.
