B.20 minutes

D.No time limit is published
Explanation: Nova Scotia's official test page says the knowledge test must be completed within 30 minutes. The separate practical pre-trip inspection times in the manual are not the online knowledge-test time limit.

About the NS Air Brake Test Exam

The Nova Scotia Air Brake Endorsement Knowledge Test is the written knowledge requirement before a driver can add an air brake endorsement to a Nova Scotia driver's licence. The Government of Nova Scotia states that the test has 20 multiple-choice questions, requires at least 16 correct answers to pass, must be completed within 30 minutes, costs $15.03, and is based on the official Nova Scotia Air Brake Manual. The manual covers braking fundamentals; compressor and governor operation; reservoirs, drains, air dryers, safety valves, gauges, low-pressure warning devices, foot valves, brake chambers, slack adjusters, S-cam brakes, spring parking brakes, dual air systems, trailer air systems, ABS, automatic traction control, brake adjustment concepts, and pre-trip air brake inspection procedures. The endorsement permits operation of air-brake-equipped vehicles in the licence class held, but after passing the knowledge test the driver still needs to visit Registry of Motor Vehicles or Access Nova Scotia to complete the additional requirements and pay the licence-upgrade fee before driving with the endorsement.

Assessment

Closed-book multiple-choice knowledge test for drivers seeking a Nova Scotia air brake endorsement. The test is based on the Nova Scotia Air Brake Manual and assesses air brake systems, including pre-trip air brake inspections.

NS Air Brake Test Study Tips from Top Performers

1Memorize the official logistics first: 20 questions, 16 correct to pass, 30 minutes, $15.03, 12-month result validity, and post-pass RMV or Access Nova Scotia completion steps.
2Learn the system as an air path: compressor, air dryer, wet reservoir, dry reservoirs, gauges, foot valve, brake chambers, slack adjusters, S-cams, and brake linings.
3Drill inspection thresholds: warning devices at 55 psi checks, 50-to-90 psi buildup within 3 minutes, governor unloading between 115 and 135 psi, loading near 80 psi, spring-brake application at or before 20 psi, and 3 psi per minute applied leakage.
4Separate service-brake operation from spring parking brake operation: service brakes apply with air pressure, while spring parking brakes apply by spring force and release with air pressure.
5Practise explaining the pre-trip inspection in sequence so numbers, actions, and reasons stay connected.
