About the Virginia General Knowledge Test
Topics Covered
- ✓Vehicle inspection — Virginia examiners expect you to know the full pre-trip inside and out, because a missed brake line check on I-95 can cost you your job.
- ✓Basic control and shifting — mountain grades on I-64 and I-77 mean you need to understand gear selection and engine braking to avoid runaway situations.
- ✓Air brakes — the most failed section in Virginia. You'll face questions on brake lag, air pressure loss, and emergency braking, especially relevant for the rolling hills west of Richmond.

📘 Study Tips & State Info
Virginia DMV examiners focus on air brakes. Hard. I've seen guys fail the General Knowledge test because they couldn't tell me the difference between a service brake application and an emergency brake application. Read the air brake section of the Virginia CDL manual twice. Then read it again. Pay special attention to the brake lag distance — that's the distance your truck travels while the air builds pressure.
Another thing: Virginia tests your knowledge of vehicle inspection procedures in detail. They don't just ask "do you inspect your tires?" They ask what you look for — tread depth, cuts, inflation. Practice the step-by-step inspection sequence until you can recite it in your sleep.
Use our practice tests to identify your weak areas. If you keep missing questions about coupling, go back to that chapter. Don't just memorize answers — understand why the correct one is right. And don't skip the sections on night driving and weather. Virginia's weather changes fast, especially in the mountains.
The Virginia DMV offers CDL knowledge testing at most Customer Service Centers. You don't need an appointment for the written test at most locations, but call ahead — some busy offices like the one on Broad Street in Richmond only take walk-ins for CDL tests during certain hours. Bring your valid driver's license, Social Security card, and a current Medical Examiner's Certificate (DOT physical). The fee for the General Knowledge test is $30. If you fail, you can retake it the next business day — no waiting period.
Virginia uses the federal CDL manual but adds state-specific information in the Virginia Commercial Driver's Manual. Download the PDF from the DMV website. Pay attention to the sections on hazardous materials routing (Virginia has specific tunnels and bridges that restrict hazmat) and the agricultural exemptions for farm vehicles. Also note: if you're under 21, you're restricted to intrastate driving only — Virginia follows federal age rules strictly.
For the skills test, you'll need to schedule an appointment with a third-party tester or at a DMV location that offers CDL skills testing. The skills fee is $60. You must pass the General Knowledge test before you can take the skills test. No exceptions.
About the Virginia General Knowledge Test
Virginia's not just I-95 through Richmond. You've got coal trucks coming out of Southwest Virginia on Route 23, log trucks winding through the Blue Ridge on Route 250, and delivery trucks fighting D.C. traffic on I-66. The General Knowledge test covers the basics every commercial driver needs — no matter what you're hauling or where you're going.
This test follows federal standards, so you'll see questions on vehicle inspection, basic control, shifting, backing, coupling, and hazard awareness. But Virginia examiners pay extra attention to air brake questions — because you don't want to lose your brakes coming down Afton Mountain on I-64. You'll also need to know how to handle fog in the Shenandoah Valley and sudden snow squalls in the mountains.
The test has 50 multiple-choice questions. You need 40 correct to pass — that's 80%. You get 60 minutes, which is plenty if you've studied. The Virginia DMV administers this test at all Customer Service Centers that offer CDL testing. You'll take it on a computer, and you get your results right away.
Don't walk in cold. This practice test mirrors the real thing — same question types, same time pressure, same Virginia focus. Use it to find your weak spots before you pay the $30 testing fee.
