What our question bank follows today
About our question bank: the 80 questions are drafted with AI from the federal knowledge areas in 49 CFR 383.111 and cite federal rules and the New York CDL manual. Your state may word items differently and tests state rules these questions do not cover. Read your own state's CDL manual too; this bank is not checked against any state's test.
Questions are AI-drafted and checked against primary sources by our process. No licensed professional has reviewed them.
What happens to practice access when a new version ships
We have not decided, so this page states no policy and makes no promise about it. It lists only what Texas Department of Public Safety publishes and what our bank follows today. When a policy exists it will be written here with the date.
