Frequently asked questions
What is PassCDL Pro?
PassCDL Pro unlocks full CDL exam prep — longer practice tests, all endorsements, pre-trip inspection questions, and unlimited retakes across every question bank.
Can I practice for free?
Yes. General knowledge, air brakes, and combination vehicles include free 20-question practice tests with explanations. No account required to start.
Should I choose monthly or annual?
Monthly ($19.99/mo) is best if you only need a few weeks of prep. Annual ($99/yr) saves about $140 if you study over several months or want to keep access while job hunting.
How much does the real CDL test cost?
Written exam fees vary by state (often $20–$50 per attempt). PassCDL helps you pass the first time so you avoid repeat fees.
Does PassCDL include ELDT theory training?
No — ELDT is a separate FMCSA-required course for new Class A/B applicants. PassCDL focuses on written knowledge test practice. See our ELDT guide for how both fit together.
Can I cancel anytime?
Yes — cancel from your account. Access continues until the end of your billing period.
What is the Pass Guarantee?
Score 80% or higher on two full Pro exam simulations, then take your DMV written within 30 days. If you still fail, contact us within 14 days with proof for a refund of your last Pro payment. See Terms for full rules.
