View All PlansSecuring a CDL without an air brake restriction is vital for expanded job opportunities in Virginia. Most semi-trucks, tractor-trailers, and commercial buses rely on air brakes for safe navigation. If you don’t pass the Virginia DMV CDL Air Brakes Knowledge Test, your CDL will include the restriction “L,” prohibiting you from operating commercial motor vehicles (CMVs) with air brakes. The steep grades of the Appalachian Mountains and Blue Ridge Parkway, and the rolling hills of the Piedmont, demand air brakes on heavy CMVs. The coastal plains and tidewater region are prone to flooding and slick road conditions, and winter’s ice and snow add additional hazards. Failing the air brakes test in Virginia results in a one-day waiting period (and retest fee) should you decide to retake the test. Our Virginia DMV CDL Air Brakes Practice Tests help you pass your knowledge exam on the first attempt.
The stop-and-go traffic of Virginia’s urban areas and major highways compounds the need for reliable air brakes. Major transportation routes include I-81 (running through western Virginia, I-64 (connecting the Blue Ridge Mountains to the coast), I-95 (running north-south along the east coast), and US-58 (running east-west).
The Old Dominion relies on drivers with the air brake qualification in key industries, including manufacturing, agriculture, logistics, defense, and energy. Major companies requiring this qualification include Newport News Shipbuilding and Northrop Grumman in the manufacturing and heavy equipment sector and FedEx Freight, UPS Freight, and XPO Logistics in the freight and logistics industry. Smithfield Foods, Perdue Farms, and Southern States Cooperative also rely on air brake-qualified drivers in the agriculture industry, as do Dominion Energy and Alpha Metallurgical Resources in energy and mining. Greyhound Lines and Virginia Motorcoach use air brake-equipped buses, as do the state school districts on full-size school buses. The “L” restriction makes the above-listed jobs unattainable.
Our CDL Air Brakes Practice Tests cover all essential knowledge for the official DMV Air Brakes Knowledge Test. The information you learn will also aid your preparations for your skills test.
