General Knowledge Practice Test 5

Every CDL applicant takes the General Knowledge test, no matter which class or endorsement you're after. It's the backbone of the written exam, covering safe commercial driving end to end — vehicle inspection, basic control, shifting, managing space and speed, spotting hazards early, and handling skids and emergencies.

This free practice set runs 50 real exam-style questions with an instant, plain-English explanation after every answer. You'll work through them about ten at a time — answer the set, then continue to the next — and your running score saves automatically. You need 40/50 to pass the real General Knowledge exam.
