Delaware CDL General Knowledge Practice Exam 2026

This real-exam rehearsal is built to feel like the genuine Delaware CDL general knowledge test, the commercial drivers license test that stands between you and your permit. Straightforward and honest: how many questions are on it? The CDL knowledge test is 50 questions, and you must answer 80 percent correctly, which is 40 right, to pass. Treat this run as the actual CDL exam, without notes and without a second guess, so your score tells you the truth about your readiness.

Every question here reflects the 2026 general knowledge content the state actually tests: vehicle inspection, basic control, space and speed management, hazard perception, and emergency procedures. Because passing this written exam is what earns your Commercial Learner's Permit, a strong result here is a direct signal that you are prepared for the real thing.

Before you sit the official test, give the Delaware CDL Manual a final review, especially any topic that surfaced a weakness in this rehearsal, since the commercial driver license manual is the source behind every question on exam day. When this real-exam simulation stops catching you out, make the call and schedule your knowledge test with the Delaware DMV.
