Manitoba Airbrake Practice Exam

What should a driver do if they experience brake failure at high speeds?

1. Steer toward the nearest exit

2. Gradually engage the emergency brake, downshift gears, and steer away from obstacles

3. Press the brake pedal hard and hold it

4. Turn off the engine immediately

The correct answer is: Gradually engage the emergency brake, downshift gears, and steer away from obstacles

When a driver experiences brake failure at high speeds, the safest and most effective response is to gradually engage the emergency brake, downshift gears, and steer away from obstacles. This method allows for controlled deceleration and helps to maintain vehicle stability. Gradually engaging the emergency brake is crucial because pulling it suddenly could cause the vehicle to skid or spin out of control, especially at high speeds. Downshifting gears helps the vehicle slow down in a controlled manner by using engine braking, which can significantly reduce speed without relying solely on the brakes. Steering away from obstacles is an essential action to avoid collisions and navigate the vehicle to a safe area, which is particularly important when brakes are not functioning properly. The other responses do not provide the same level of control or safety in this critical situation. Steering toward the nearest exit could lead to further hazards depending on the surrounding environment. Pressing the brake pedal hard and holding it would not be effective since the brakes have already failed. Turning off the engine immediately could also cause a loss of control, as it would eliminate power steering and power brakes, making the vehicle harder to manage. Therefore, the combination of engaging the emergency brake, downshifting, and steering clear of obstacles is essential for safely handling brake failure
