Pennsylvania CDL General Knowledge Practice Test 1: what to expect and what trips drivers up

This is the flagship Pennsylvania CDL practice test for 2026, built to be the fastest route from studying to a passing score. It works as a free CDL practice test online covering the general knowledge material every commercial driver in the state must master, and it doubles as a Pennsylvania CDL permit test because the written exam for the Commercial Learner's Permit asks about exactly the same topics.

How many questions are on the Pennsylvania CDL general knowledge test? There are 50, and you need to answer 40 correctly for the 80 percent score that passes. That threshold comes from the federal FMCSA, not PennDOT, which is why it holds in every state. Class A, B, and C applicants all take this one written test; the class you earn depends on the skills exam and the vehicle you drive.

Pennsylvania's freight economy makes the CDL worth chasing: the Lehigh Valley and the I-78, I-81, and I-76 corridors have grown into one of the East Coast's busiest warehousing belts, while steel and manufacturing still put heavy loads on the road. Drill this Pennsylvania Commercial Driver's Manual based practice test until 40 out of 50 comes without hesitation, then book your PennDOT skills test.

Keep going:

Every question traces back to the Pennsylvania CDL Manual - skim the right-of-way and signs chapters before your retake.
