Do Crist CDL practice tests use the real test questions?

Crist commercial driver's license practice tests do not use the real test questions. While the guidelines for acquiring a CDL originated on the federal level, each state wrote its own test with either true/false questions or multiple-choice questions.

Some of the questions on the Crist practice test seem similar to the actual test questions, because the information for the test originates from a single source. Crist offers more than 400 questions concerning a CDL over several tests and 165 general knowledge questions separated into 11 tests of 15 questions each. When an answer on the test differs from the answer found in the state's handbook, the student needs to learn the state's answer.
