- You need 80% to pass, and Virginia DMV allows only one attempt per business day.
- Class A candidates must pass General Knowledge, Air Brakes, and Combination Vehicles separately.
- A CLP costs $3; a standard eight-year CDL runs $64, plus $1 per year for each endorsement.
- Your CLP is valid one year, cannot be renewed, and must be held 14 days minimum before skills testing.

The Three VA-CDL Knowledge Tests
For the unrestricted Class A path, Virginia requires three separate computerized knowledge tests. Each is scored independently, and each demands its own 80% passing threshold. Treat them as three distinct exams, not one combined test.
Domain 1: General Knowledge
This is the foundation test every CDL applicant takes, regardless of vehicle class. It covers the rules, safety practices, and vehicle-handling concepts that apply broadly to commercial driving.
- Core traffic and safety regulations for commercial vehicles
- Basic vehicle inspection and control concepts
- Required for every CDL applicant, not just Class A candidates
Domain 2: Air Brakes
Any applicant driving a vehicle equipped with air brakes must pass this separate test. Skipping it - or failing it - results in a restriction on the license.
- Air brake system components and function
- Warning signs of brake system problems
- Directly tied to whether your license carries an air brake restriction
Domain 3: Combination Vehicles
This test is required for anyone pursuing the unrestricted Class A credential, since it addresses how tractor-trailer and other combination units behave differently from straight trucks.
- Coupling and uncoupling procedures
- Handling characteristics unique to combination units
- Required alongside General Knowledge and Air Brakes for full Class A privileges
For a deeper walkthrough of exactly what each of these three content areas covers, see the VA-CDL Exam Domains 2026: Complete Guide to All 3 Content Areas. If you're still weighing how tough this combination actually is compared to a single-test credential, How Hard Is the VA-CDL Exam? Complete Difficulty Guide 2026 addresses that question directly.
Key Takeaway
Study Air Brakes and Combination Vehicles as connected subjects - brake behavior in a combination unit is a frequent overlap point between the two tests.
Fees & Costs Cheat Sheet
Virginia's CDL fee structure is straightforward, but it's easy to underbudget if you're only counting the permit fee. Here's the full picture:
- Commercial Learner's Permit (CLP): $3
- Standard eight-year CDL, no endorsements: $64
- Each endorsement: $1 per year (multiply by the years on your credential)
Endorsement costs scale with the length of your license term, so a HazMat or tanker endorsement added to an eight-year CDL costs more than the same endorsement on a shorter renewal cycle. For a line-by-line breakdown of every fee scenario, check the VA-CDL Certification Cost 2026: Complete Pricing Breakdown.
Eligibility & Documentation Checklist
Before you can even sit for a knowledge test, Virginia DMV requires you to apply in person and satisfy several eligibility checks. Miss one, and your appointment stalls.
- Minimum age of 18 for intrastate operation, or 21 for interstate operation
- Proof of identity and legal presence
- Social Security number verification
- Proof of Virginia residency
- Satisfaction of medical requirements and self-certification
- Completion of applicable Entry-Level Driver Training (ELDT)
Note also that Virginia has stopped issuing non-domiciled CLPs and CDLs, so applicants without a Virginia domicile will need to pursue credentialing through their state of legal residence instead. The full eligibility rundown, including document specifics, lives in VA-CDL Requirements 2026: Eligibility, Prerequisites & How to Qualify.
CLP Rules You Cannot Forget
The Commercial Learner's Permit is where most scheduling mistakes happen. Three rules define its entire lifecycle:
- One-year validity. Your CLP expires exactly one year after issuance.
- No renewal. If it lapses, you restart the CLP process - there is no extension.
- 14-day minimum hold. You must hold the CLP for at least 14 days before you're eligible to schedule skills testing.
This means the practical window for completing skills testing sits somewhere between 14 days and roughly a year after you pass your knowledge tests. Build your training and practice schedule around that window rather than assuming you have unlimited time.
Key Takeaway
Schedule your skills test appointment as soon as you clear the 14-day minimum hold - waiting too long risks running into the one-year CLP expiration with no renewal option.
Passing Score & Retest Rules
Every knowledge test - General Knowledge, Air Brakes, Combination Vehicles, and any endorsement exam - requires an 80% score to pass. There's no partial credit or curve, and no combined average across tests; each one stands on its own.
Retesting is limited to one attempt per business day. If you fail, you'll need to wait until the next business day to try again, so a single day of testing yields only one shot per subject. This makes preparation, not repetition, your best strategy. See VA-CDL Passing Score 2026: Exactly What You Need to Pass for a closer look at how scoring works, and VA-CDL Pass Rate 2026: What the Data Shows for context on how candidates typically perform.
One-Week Domain Review Plan
If your test date is close, a compressed weekly plan built around the three domains keeps review focused instead of scattered. Rather than generic study advice, sequence your week around which domain feeds into which.
General Knowledge
- Review core safety rules and vehicle inspection basics first - this domain underlies the other two
- Take practice questions daily to build recall speed
Air Brakes
- Focus on brake system components and warning signs
- Connect this material to combination-vehicle braking behavior ahead of Domain 3
Combination Vehicles
- Study coupling/uncoupling procedures and handling differences
- Cross-reference brake concepts from the prior two days
Full Review & Scheduling
- Run mixed practice sets across all three domains
- Confirm your DMV appointment and required documents
This structure is intentionally short because passed results only last a year and you only get one attempt per day - there's no benefit to dragging out review indefinitely. For a longer-term prep framework, the VA-CDL Study Guide 2026 covers pacing options beyond this compressed week. You can also run full-length practice sessions on our VA-CDL practice test platform to simulate the computerized format before test day.
Test Day Quick Reference
Print or screenshot this section for the morning of your appointment:
- Bring identity, legal presence, Social Security, and Virginia residency documents
- Confirm you meet the medical and self-certification requirements on file
- Test language: several languages are available, except HazMat, which is English-only
- You get one attempt per business day per test - arrive prepared to pass, not to guess
- Ask about ELDT completion proof if it applies to your intended class
