New York CDL holders can add endorsements for Hazardous Materials (H, 30 questions), Tanker Vehicles (N, 20 questions), Double/Triple Trailers (T, 20 questions), Passenger Transport (P, 20 questions), and School Bus (S, 20 questions).

Do I need to hold a CLP before the CDL skills test in New York?

Yes. You must hold a valid Commercial Learner Permit (CLP) for at least 14 days before taking the CDL skills test. The CLP is issued after you pass the required CDL knowledge tests at a New York DMV office. During the CLP period you must practice with a qualified CDL holder seated beside you.

What is the age requirement for a New York CDL?

You must be at least 18 years old for intrastate (within New York State) CDL driving. You must be at least 21 to operate in interstate commerce, transport hazardous materials, or drive a bus that crosses state lines.

What is Entry-Level Driver Training (ELDT) and do I need it?

ELDT is federally required theory and behind-the-wheel training from an FMCSA-registered school. It is mandatory for first-time Class A or B CDL applicants and for anyone adding a Passenger (P) or School Bus (S) endorsement. Your training provider submits completion electronically to the FMCSA Training Provider Registry before you can take the CDL skills test.

About this section of the New York test

New York requires a Commercial Driver's License (CDL) for operators of commercial vehicles including tractor-trailers, straight trucks, and buses. The CDL General Knowledge test is 50 multiple-choice questions — you need 40 correct (80%) to pass and receive your Commercial Learner Permit (CLP). After holding the CLP for at least 14 days, you take the CDL skills test (pre-trip inspection, basic vehicle control, and on-road driving). Applicants for Class A or B licenses must also complete Entry-Level Driver Training (ELDT) from an FMCSA-registered school. Minimum age is 18 for intrastate (within New York) commerce; 21 for interstate commerce, hazmat, or cross-state bus routes. Endorsement written tests cover Air Brakes (25 questions), Combination Vehicles (20), Passenger Transport (20), School Bus (20), Hazardous Materials (30), and Tanker Vehicles (20) — all with an 80% passing score. Hazmat applicants also require a TSA security threat assessment. CDL fees in New York are $164.50 for Class A or B, and $80 for Class C. All CDL knowledge testing is completed in person at a New York DMV office.

2026 New York CDL update

New York CDL requirements for 2026 are aligned with the latest FMCSA federal standards. Entry-Level Driver Training (ELDT) from an FMCSA-registered provider is now mandatory for all first-time Class A or B CDL applicants and for Passenger and School Bus endorsement seekers. The Commercial Learner Permit (CLP) must be held for a minimum of 14 days before scheduling the CDL skills test. The General Knowledge test is 50 questions (80% passing), and each endorsement written test is 20–30 questions with the same 80% threshold. Questions are drawn from the FMCSA's Commercial Driver's License Manual and New York DMV supplements. Air brakes knowledge is required for most Class A vehicles — skipping that test results in a permanent air brakes restriction on your CDL.
