Virginia CDL Test Questions 2026: Format and Study Guide
Virginia CDL knowledge-test guide for 2026: 80% passing score, once-per-business-day testing, class and endorsement topics, languages, and study strategy.
Virginia's commercial knowledge exams are based on the Virginia Commercial Driver's Manual. Instead of memorizing a third-party question bank, identify every exam your desired class and endorsements require and study the matching manual sections.
Passing Score
Virginia DMV requires at least 80% on the CDL knowledge exams. The exams are computer-based and require selecting the best answer.
General Knowledge
Every Class A, B, and C commercial applicant takes General Knowledge. The DMV directs applicants to the safe-driving, cargo, and Virginia supplement material identified in the Commercial Driver's Manual.
Air Brakes
If you intend to operate a vehicle with air brakes, take the air-brake knowledge exam and study the dedicated air-brake section. Skipping the applicable exam can create a restriction on the commercial license.
Combination Vehicles
Class A applicants study the combination-vehicle material covering tractor-trailer operation, coupling, inspections, trailer behavior, and combination-vehicle safety.
Endorsements
Virginia requires separate knowledge exams for endorsements such as HazMat, Tank, Passenger, School Bus, and Doubles/Triples. HazMat applicants must complete the required ELDT theory before completing the HazMat knowledge exam.
Languages
Virginia offers CDL knowledge exams in multiple languages, including English, Spanish, Dari, Pashto, and others. HazMat is the important exception: Virginia DMV states that the HazMat knowledge exam is given only in English and cannot be taken with a translator.
Retest Timing
Virginia limits CDL knowledge exams to one attempt per business day. If you use a cell phone during an exam, DMV terminates the exam and you must wait until the next day to retest.
Validity of Passing Results
Virginia states that passing CDL knowledge-test results remain valid for one year. You must obtain the CDL or CLP within that period or retake the knowledge test.
Study Strategy
- Choose the exact CDL class and endorsements required for the job you want.
- Use Virginia DMV's test chart to identify the required manual sections.
- Study the manual before drilling practice questions.
- Review wrong answers by topic, not only by question wording.
- Practice inspections, air-brake logic, and combination-vehicle rules until you can explain why an answer is correct.
- Stop using a phone or unauthorized material during the actual exam; Virginia treats that as a testing violation.
