What is different in New York

New York in particular

New York keeps CDL knowledge testing strictly in house at DMV offices rather than allowing any third party administration, a stricter stance on the written portion than several neighboring states take.

The written exams themselves are federal

New York decides the permit rules, the fees and who runs the skills test, but the knowledge you are tested on comes from 49 CFR Part 383 and is the same in every state, which is why the 145 questions here work wherever you apply.
