About DriveTruck.org
DriveTruck.org is a free CDL prep site covering all 50 U.S. states + Washington DC. It's a sister site to DriveCar.org, which serves the same role for non-commercial DMV permit tests.
What we do
- Summarize each state's CDL process — ages, fees, CLP hold, retake rules, ELDT.
- Generate practice tests for General Knowledge, Air Brakes, Combination, and all six endorsements.
- Cite official sources for every fact.
- Keep content updated each year.
Citation policy
Every state fact we publish has a visible citation linking back to the official state DMV/DOT page or to the relevant section of 49 CFR (Part 383, 380, 391). If you find a stale or wrong citation, tell us.
What we don't do
- We are not affiliated with the FMCSA, any state DMV, or any state DOT.
- We don't sell, share, or store personal data — there are no user accounts.
- We don't claim the practice questions match the exact wording of the real exam.
