How the practice works

  • Practice mode — questions appear one at a time, with the explanation and source citation after each. Take your time. Your progress saves for 24 hours.
  • Mock exam mode — 20 questions, no per-question feedback, timed. Closest to the real exam experience. Review all explanations at the end.
  • Weak topic detection — at the end, we highlight the topics you scored below 70% on so you know where to focus.

Where these questions come from

Every question in this practice test was written by the 247SimpleTests Editorial Team from FMCSA Commercial Driver's License Manual, Section 10 (public domain).. We do not reproduce or scrape questions from the real exam — that would be copyright infringement and would not help you understand the material. Instead, we write originals that test the same underlying knowledge using different wording. Each question lists the section of the source handbook it was drawn from.
