CDL Quest is source-backed CDL practice built around honest learning evidence. Practice follows the federal CDL core and your selected class and endorsements. Your state supplies its official agency manual and local permit context. Build knowledge through 610 questions across eight banks. Each topic separates canonical coverage, aggregate accuracy, and practice evidence, so a short quiz never overstates the breadth of practice completed. Practice Readiness summarizes only your in-app activity and is not a pass prediction. Recall-first Pre-Trip practice lets you make an inspection call aloud before revealing the keyed call, coaching, and source cue. You then self-check what you covered. CDL Quest does not listen to, record, or send your voice. Multiple Choice remains available as an alternative. Three coached drives contain seven fixed decision points. Compare safe and unsafe choices, then review the consequence; the scenarios do not branch. Starter includes: - All 158 General Knowledge questions - One route-wide mock preview - One pre-trip zone - One road scenario - Existing offline/local study tools Pro includes: - All 610 questions across eight banks - Challenge Bank, Weak Topic Sprint, and Mixed Route Drill - Unlimited route mocks - All route-applicable pre-trip zones and full walkaround - All three road scenarios Pro Monthly is $2.99 per month and renews automatically unless canceled. Pro Lifetime is a $19.99 one-time purchase for current Pro study tools. Prices are localized by the App Store. Restore Purchases, Manage Subscription for monthly access, Privacy Policy, and Terms of Use are accessible in the app. CDL Quest is an independent study app. It is not a government, DMV, FMCSA, or state licensing agency app, does not reproduce an exact exam, and does not guarantee passing.
