Free Nevada CDL Air Brakes Test 2025
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
The Silver State relies on drivers with the air brake qualification in key industries, including mining (gold, silver, and lithium), tourism (Las Vegas, Reno, and Lake Tahoe), agriculture (cattle, hay, and alfalfa), and logistics and transportation. Failure to pass the Nevada DMV CDL Air Brakes Knowledge Test means that your CDL will include the restriction “L,” preventing you from operating commercial motor vehicles (CMVs) with air brakes. This “L” restriction will negatively affect your job prospects in these markets. Failing the air brakes test in Nevada will also result in a one-day waiting period and a fee should you decide to retake the test. Our Nevada DMV CDL Air Brakes Practice Tests are the perfect tool for passing your knowledge exam on the first attempt.
Navigating Nevada’s diverse terrain, including the steep grades and sharp curves of its mountains, demands the reliability of air brakes on heavy rigs. Additionally, the higher elevations experience winter ice and snow, compounding this need. Key transportation routes include I-80 (an east-west corridor crossing mountain passes like the Donner Pass), I-15 (running north-south through Las Vegas, connecting California and Utah), and US-95 (running north-south through deserts and mountains). Most semi-trucks, tractor-trailers, and commercial buses rely on air brakes for safe travel. Hence, removing the restriction from your CDL is vital for expanded job opportunities.
Companies requiring the air brake qualification include Swift Transportation (Reno) and Knight Transportation (Las Vegas) in the trucking industry and Greyhound Lines and Alliance Bus Group in the charter bus sector. The mining industry includes major companies like MP Materials Corp. and Nevada Gold Mines, which rely on air brake-qualified drivers. Prologis and Total Quality Logistics require the same in the tourism industry. Nevada’s school districts use air brakes on their full-size buses, employing hundreds of air brake-qualified drivers. The “L” restriction makes these jobs unattainable.
The written Air Brakes knowledge test features multiple-choice questions based on the state’s CDL manual (Nevada CDL Handbook 2025) and requires a minimum passing score of 80%. Our practice tests provide instant feedback on all your responses, helping ensure you pass the knowledge test. As a bonus, the information learned will also help you prepare to pass your skills test!
