Practice the in-cab air-brake inspection in an interactive simulator built for aspiring commercial drivers. Virtual CDL Simulator lets you work through realistic practice sequences using responsive primary and secondary pressure gauges, trailer air-supply and parking-brake controls, ignition and engine controls, the service brake, accelerator, and wheel chocks. TRAIN THREE WAYS • Learn — follow guided instructions and see the correct next action. • Practice — repeat the procedure and build confidence at your own pace. • Test — perform the sequence without hints and receive immediate feedback when an action is out of order. PRACTICE KEY AIR-BRAKE CHECKS • Governor cut-in and cutout • Static and applied leakage checks • Low-air warning activation • Automatic spring-brake application • Truck-only and truck-and-trailer configurations The app uses a Texas Class A training profile and is intended for U.S. CDL study and skills practice.
