View All PlansBecause most semi-trucks and tractor-trailers rely on air brakes for safe navigation, securing a CDL without an air brake restriction is an absolute priority for anyone wanting to expand their job opportunities. Without passing the Rhode Island DMV CDL Air Brakes Knowledge Test, your CDL will include the restriction “L,” preventing you from operating commercial motor vehicles (CMVs) with air brakes. This restriction closes the door to a multitude of jobs. A one-day waiting period and retest fee (should you decide to take it again) will result if you fail the air brakes test in Rhode Island. Our Rhode Island DMV CDL Air Brakes Practice Tests will help you pass your knowledge exam on the first attempt.
Rhode Island’s diverse terrain, which includes flat coastal areas, hilly inland terrain, congested urban zones (especially in Providence), and narrow roadways, makes precise braking control critical. Key transportation routes, such as I-95 (a major highway connecting Rhode Island to Massachusetts and Connecticut), Route 146 (linking Providence and Worcester), and Routes 4 and 6 (connecting rural-to-urban areas of the state), demand air brake-qualified drivers for safe operation. Without the air brake qualification, drivers face limited access to jobs in commercial trucking and public transit.
The Ocean State relies on drivers with the air brake qualification in key industries, including tourism and hospitality (especially in coastal destinations), manufacturing, agriculture, and seafood. Major companies requiring this qualification include Penske Truck Leasing (Providence), UPS and FedEx in the logistics industry, and Rhode Island Public Transit Authority (RIPTA) and Peter Pan Bus Lines (Providence) in the public transit and charter services. Rhode Island also has thousands of full-size school buses that require air brake-qualified drivers. The “L” restriction makes all of these jobs (and many more!) unattainable.
Based on the state’s CDL manual (Rhode Island CDL Handbook 2025), the written Air Brakes knowledge test features multiple-choice questions and a minimum passing score of 80%. Our CDL Air Brakes Practice Tests cover all essential knowledge for the official DMV Air Brakes Knowledge Test. The material covered will also be useful as you practice inspecting and operating CMVs to pass your skills test. Additionally, our practice tests mimic the official knowledge test and offer real-time feedback on all responses. This immediate display of feedback is scientifically proven to help you learn faster and ensure you pass the test.
