Store description excerpt
Prepare for the commercial learner's permit and practice the inspection calls that matter around a real vehicle. CDL Permit & Pre-Trip Lab includes: - 320 original questions across eight permit and endorsement routes - General Knowledge, Air Brakes, Combination, Tank, Doubles/Triples, Passenger, School Bus and Pre-Trip coverage - Original explanations and source keys for every question - 50-question readiness checks with an explicitly educational study target - Weak-route repair, bookmarks and private on-device progress - A recall-before-reveal walkaround covering ten inspection zones - A guided air-brake sequence and pressure-loss rate calculator - Coupling decision scenarios and a local class/endorsement route planner - Date-stamped FMCSA and eCFR sources - Offline operation after installation The free download includes four questions in every route, one readiness check, two pre-trip zones, two air-brake steps, the route planner, pressure calculator and official sources. A US$19.99 non-consumable purchase unlocks all current questions and labs, unlimited readiness checks, repair and bookmarks. There is no subscription. This independent educational tool does not issue a CLP/CDL, provide ELDT certification, replace vehicle-specific inspection instructions or guarantee a passing result. Each state has its own manual and test process. The current state manual, vehicle instructions and examiner directions control. No account, advertising, tracking, analytics SDK or cloud profile is used.
