Question Analysis

According to the Alberta Driver's Guide, when your vehicle is equipped with ABS, the correct technique for an emergency stop is to apply firm, steady pressure to the brake pedal and hold it. Do not pump the brakes, as ABS automatically modulates brake pressure to prevent wheel lockup. This allows you to maintain steering control while stopping as quickly as possible.

Correct Answer Analysis

Correct Answer: Apply firm, steady pressure to the brake pedal and hold it — do not release

The correct answer is 'Apply firm, steady pressure to the brake pedal and hold it — do not release.' This is because ABS is designed to automatically pump the brakes at a high frequency, so you should keep constant pressure on the pedal. This maximizes braking force while allowing you to steer around obstacles if needed.

Wrong Options Analysis

Option: Pump the brake pedal rapidly

This is incorrect because pumping the brakes manually is unnecessary and counterproductive with ABS. The system already modulates brake pressure, and manual pumping can reduce braking effectiveness and increase stopping distance.

Option: Apply and release the brake pedal alternately every second

This is incorrect because it mimics manual pumping, which is not recommended with ABS. It can cause the system to not function optimally and may lead to loss of steering control during an emergency stop.

Option: Steer first and brake second

This is incorrect because in an emergency stop, you should brake firmly and steer simultaneously if needed. Delaying braking to steer first can increase stopping distance and reduce your ability to avoid a collision. With ABS, you can brake and steer at the same time.
