New York CDL Test Questions 2026: Format and Study Guide
New York CDL knowledge-test guide for 2026: 80% passing standard, test topics, languages, retake policy, endorsements, and how to use the CDL-10 manual.
The safest way to prepare for a New York CDL knowledge test is to study by manual section, not by memorizing a third-party question count. New York's Commercial Driver's Manual explains which sections apply to each license class and endorsement and states that commercial knowledge tests use multiple-choice questions with one correct answer from three choices.
Passing Score
The New York State Commercial Driver's Manual states that the passing score for each commercial driver knowledge test is 80%. That standard applies across the commercial knowledge tests described in the manual.
General Knowledge
Every CLP or CDL applicant takes the General/Core Knowledge test. The manual directs all applicants to core material that includes safe driving, cargo, inspections, and skills-test concepts. Do not study only a list of isolated answers; understand the operating rule behind each question.
Air Brakes and Combination Vehicles
Applicants who need to operate air-brake vehicles should study the dedicated air-brake section to avoid an air-brake restriction. Class A applicants must also understand combination-vehicle operation, including coupling, inspections, trailer behavior, rollover and jackknife risks, and safe control of tractor-trailer combinations.
Endorsements
Additional tests apply to endorsements such as HazMat, Tank, Passenger, School Bus, and Doubles/Triples. HazMat also has federal ELDT and security requirements beyond the knowledge exam itself.
Languages
New York currently offers standard commercial Class A, B, C and endorsement knowledge tests in English, Spanish, Chinese, and Russian. The HazMat endorsement test is English-only.
Retakes
The New York CDL manual says there is no fixed numerical limit on commercial knowledge-test retakes, although retesting remains subject to DMV office management and applicable fees. The initial $10 commercial application covers written tests taken at the same time; New York lists an additional $5 fee for another required test not taken and passed at the initial application.
Do Not Confuse CDL and Regular-License Question Counts
New York's ordinary Class D written test has a separately published question count and road-sign requirement. Those numbers are not the CDL test. Use CDL-10 for commercial testing and avoid copying Class D figures into a CDL guide.
A Better Study Method
- Identify the class and endorsements you need.
- Use CDL-10 to map each required test to its manual sections.
- Read the manual before using practice questions.
- Use practice questions to identify weak topics rather than memorizing answer order.
- Review every wrong answer and return to the manual section that explains the rule.
- Spend extra time on inspections, air-brake checks, and combination-vehicle safety if those tests apply.
