Failure to pass the West Virginia DMV CDL Air Brakes Knowledge Test means that your CDL will include the restriction “L.” This restriction negatively impacts your job prospects by preventing you from operating commercial motor vehicles (CMVs) with air brakes. Failing the air brakes test in West Virginia also results in a one-day waiting period and a fee should you decide to retake the test. Our West Virginia DMV CDL Air Brakes Practice Tests provide the tools to pass on the first attempt.
From the steep grades and sharp curves of the Appalachian Mountains to its narrow, winding rural roads, West Virginia poses challenging driving conditions that demand the reliability of an air brake system. Air brake-qualified drivers are essential for the transport of goods, especially when winter ice and snow compound the road hazards. Key transportation routes that require skilled air brake operation include I-64 (an east-west mountainous highway), I-77 (connecting West Virginia to Ohio and other Appalachian regions), and US-50 (featuring steep grades and sharp curves). Since most semi-trucks, tractor-trailers, and commercial buses rely on air brakes for safe navigation, removing the air brake restriction from your CDL is crucial for expanded job opportunities.

The Mountain State relies on drivers with the air brake qualification in key industries, including coal, chemical manufacturing, tourism, and forestry. Companies requiring air brake qualified drivers include Mountain State Waste (Charleston) and Eagle Freight System (Huntington) in the trucking industry, as well as Greyhound Lines and Kanawha Valley Regional Transportation Authority (both out of Charleston) in the charter bus industry. The coal and mining industry in West Virginia relies on air brake-qualified drivers in companies like Black Hawk Mining, LLC, Coal-Mac, LLC, and Alpha Metallurgical Resources. Additionally, West Virginia’s school districts use air brakes on their full-size buses and provide jobs for hundreds of qualified drivers. The “L” restriction makes these opportunities unattainable.
