New York CDL General Knowledge Practice Test

The New York CDL General Knowledge test has 50 questions. You must answer at least 40 correctly — a passing score of 80% — to pass and receive your CDL learner's permit.

New York issues three CDL classes: Class A (combination vehicles over 26,001 lbs GVWR towing a unit over 10,000 lbs), Class B (single vehicles over 26,001 lbs, or towing a vehicle under 10,001 lbs), and Class C (vehicles transporting 16+ passengers or HazMat requiring placards).

Yes. New York City has a complex designated truck route system. Commercial vehicles must use designated truck routes unless making a local pickup or delivery. Some bridges and tunnels also have specific restrictions for commercial vehicles based on height, weight, or HazMat cargo. Always review route restrictions before operating in NYC.

A New York State CDL is valid for 8 years for most drivers. HazMat endorsement holders must complete a TSA security threat assessment renewal every 5 years. Your DOT medical certificate must remain current for the full CDL validity period.

You must pass the CDL General Knowledge test plus any endorsement-specific knowledge tests required for your vehicle class and intended operation. Common endorsements requiring additional knowledge tests include: HazMat (H), Passenger (P), School Bus (S), Tanker (N), and Doubles/Triples (T). Air Brakes requires a separate knowledge test to remove the restriction.

A Class A CDL allows you to operate any combination of vehicles with a Gross Vehicle Weight Rating (GVWR) of 26,001 lbs or more, provided the towed unit exceeds 10,000 lbs — this includes tractor-trailers and double/triple trailer rigs. A Class B CDL covers single vehicles with a GVWR of 26,001 lbs or more, or any such vehicle towing a unit not exceeding 10,000 lbs — this includes straight trucks and large buses. A Class C CDL is required for vehicles designed to carry 16 or more passengers (including the driver) or for vehicles transporting hazardous materials that require placarding, when those vehicles do not qualify for Class A or B.

CDL fees vary by state and by the class and endorsements you obtain. Most states charge separate fees for the CDL knowledge test ($10–$30 per attempt), the CDL skills test ($50–$150), and the CDL license itself ($50–$100). Additional fees apply for each endorsement (HazMat, Tanker, Passenger, etc.). The HazMat endorsement also requires a TSA security threat assessment fee of approximately $86. Check your New York DMV website for current fee schedules.

Federal regulations (49 CFR 383.133) require that CDL applicants be able to read and speak the English language sufficiently to understand highway traffic signs and signals and to respond to official inquiries. Many states offer CDL knowledge tests in Spanish and other languages for non-commercial knowledge questions, but the actual CDL test must be taken in a language that allows the driver to meet the English proficiency requirement. Check with the New York DMV for available language options.

In most states, a CDL is valid for 4–8 years (commonly 4–5 years). To renew your New York CDL, you typically need to visit a DMV office, pass a vision test, pay the renewal fee, and update your medical certification (DOT physical). If you hold a HazMat endorsement, your TSA background check must also be current. CDLs cannot generally be renewed online due to federal requirements for in-person verification of medical certification.

If you fail the CDL General Knowledge test in New York, you are typically required to wait a specified period (commonly 1–7 days) before retaking it. Most states allow 2–3 attempts before requiring additional waiting periods or study requirements. There is usually a retest fee for each attempt. Focus on the areas you missed — most states provide a score sheet showing which topic areas you need to review.
