Get ready for your CDL knowledge tests with free practice tests from ELDT.Courses, an FMCSA-registered training provider.

SEVEN PRACTICE TESTS, SAME LENGTH AS THE REAL ONES
• General Knowledge – 50 questions
• Air Brakes – 25 questions
• Combination Vehicles – 20 questions
• Hazardous Materials (H) – 30 questions
• Tank Vehicles (N) – 20 questions
• Doubles and Triples (T) – 20 questions
• New York Metal Coil (M) – 20 questions
You need 80% to pass, just like the real knowledge tests. Questions are drawn from large banks, so every test is different.

LEARN WHY, NOT JUST WHAT
• Every answer comes with a short explanation and where the rule comes from (the CDL manual or federal regulations).
• Easy-to-remember hints on many questions.
• Choose to see the right answer right away, or all at the end like the real test.
• Skip a question you're unsure of and come back to it at the end.

SHORT ON TIME?
• Take a mini-test of 5, 10, 15 or 25 questions.
• Full-length tests track your best and last score. Score 80% or better on three full tests in a row and the app shows you're ready.

STUDY GUIDE BY EMAIL
• Get the questions you missed emailed to you as a study guide: your answer, the right answer, why, and a hint.

FOR STUDENTS OF A TRAINING SCHOOL
• Join your school with its short name and 4-digit code. The app shows your school's logo and colors.
• Your school can see your progress and scores.

SIGN IN YOUR WAY
• Use your email, an ELDT account, or your ELDT.Courses / school Moodle sign-in.

Questions are written from the CDL manual most states use and current federal rules, and are checked every month. These are practice questions, not the official test. Your state's licensing agency gives the real knowledge tests, and some state rules differ, so check your state's CDL manual too.
