The agriculture, energy, freight, military transport, and shipbuilding sectors keep the Virginia Commonwealth economy moving, and most commercial motor vehicles (CMVs) rely on air brakes for vehicle control. Securing a commercial driver’s license (CDL) without an air brake restriction is one of the most important steps you can take if you want to operate CMVs equipped with air brakes. If you do not pass the Virginia DMV CDL Air Brakes Knowledge Test, the restriction “L” will remain on your license, preventing you from operating any CMV equipped with an air brake system. That immediately closes the door to some of the highest-paying and most in-demand driving jobs in the state. Our series of Virginia CDL Air Brakes Practice Tests is the perfect tool for passing the official exam on your first attempt.
Virginia features some of the most diverse terrain in this region of the country. The Appalachian Mountains, the winding passages along I-81, the Blue Ridge Parkway, the rolling hills of the Piedmont, and the steep grades and narrow rural routes demand precise braking systems, and air brakes are a requirement on many commercial vehicles. In big cities like Norfolk, Richmond, and the northern Virginia area, stop-and-go traffic creates a need for reliable braking on commercial rigs. In short, the state is rife with features that demand the use of air brakes, and removing that restriction from your CDL is paramount to expanding your pool of driving opportunities.

Failing the official air brakes test results in a fee and a mandatory one-day minimum waiting period before retesting. With transportation positions at major companies like Alpha Metallurgical Resources, Dominion Energy, FedEx Freight, Newport News Shipbuilding, Northrop Grumman, Perdue Farms, UPS Freight, XPO Logistics, and Smithfield Foods, that “L” restriction can mean the difference between getting the job and not. Many full-size school buses across Virginia and the coach buses of Greyhound and Virginia Motorcoach are air brake-equipped, offering even more opportunities.
The official test consists of 25 multiple-choice questions, requiring a minimum passing score of 80%. Our CDL Air Brakes Practice Tests mirror the official exam format and include AI-driven immediate feedback to speed learning and increase retention. Also featured is an interactive CDL Manual and a Challenge Bank of questions that remembers any you miss and presents them again until mastery is achieved.
