Pennsylvania CDL Written Test — Questions, Cost & Study Tips (2026)

Published June 25, 2026

Studying for your Pennsylvania CDL written exam? Here is what applicants typically need to know before visiting PennDOT.

How many questions on the Pennsylvania CDL test?

Pennsylvania general knowledge written exams commonly include about 50 multiple-choice questions for the core CDL knowledge test. Endorsements such as air brakes, combination vehicles, hazmat, and passenger are separate written tests if your license class requires them.

PassCDL mirrors this structure: start with general knowledge, then add endorsement practice for the tests you need.

Pennsylvania CDL test cost (approximate)

Written exam fees at PennDOT are typically $25–$45 per attempt (varies by office and endorsement). Failing and retesting can cost more than a month of PassCDL Pro — many students prefer unlimited practice before test day.

Pennsylvania study tip

PennDOT CDL knowledge tests follow federal standards — combination vehicles required for Class A.
