New York CDL General Knowledge

It is the core written knowledge exam required for a New York commercial driver license. It checks whether you understand the material in the General Knowledge sections of the state Commercial Driver's Manual, document CDL-10, before you move on to endorsements and the skills test.

The General Knowledge material in CDL-10 spans Sections 1, 2, 3, 7, 8 and 10 - introduction, driving safely, transporting cargo safely, vehicle inspection, basic control, and the special requirements and hazards of commercial driving. Treat each section as its own study block rather than reading straight through.

The source material available here does not state the question count or passing score, so those figures are not given on this page. They can change, so verify the current format and passing requirement with the New York State DMV before your appointment rather than relying on a study site.

Most failures come from shallow reading, not from the material being obscure. Candidates who skim the manual miss the reasoning behind inspection, cargo securement and speed-management questions. Read each section for understanding, then re-test yourself until you can explain why the wrong answers are wrong.

Retake rules, waiting periods and any fees are set by the DMV and are not stated in the source material available here. Check the DMV's commercial driver license pages or ask at the office where you test, since the policy in force when you test is the one that applies to you.

Start with Section 1 for the CDL framework and Section 2 for safe driving, since later material builds on them. Then take Section 3 cargo securement, Section 7 vehicle inspection, Section 8 basic control and Section 10 special requirements. Finish with mixed practice so you cannot predict the topic from the question order.

Three recur. First, memorizing answers without understanding the underlying rule, which collapses when a question is worded differently. Second, skipping vehicle inspection and cargo securement because they feel less intuitive. Third, studying from an outdated copy of the manual instead of the current CDL-10 sections from the DMV.

No. General Knowledge is the foundation, and endorsement tests such as those for air brakes, tank vehicles or passenger operations build on it. Pass the core test first, then add the endorsements your intended job or vehicle type requires, checking the DMV's requirements for each.

The New York State DMV publishes the Commercial Driver's Manual as document CDL-10, with a table of contents and separate section PDFs on its website. Download the sections directly from the DMV so you are studying current text, and confirm any format, fee or scheduling details there before testing.
