Topic: Using an
Anti-Lock Brake System Effectively
Topic Goal: To develop the
novice driver knowledge needed to effectively use anti-lock brake systems under
normal and adverse driving conditions.
Performance
Outcomes
The student will be able to:
- describe four advantages of anti-lock braking systems
(ABS).
- explain how to recognize a vehicle equipped with ABS.
- describe how ABS improves steerability and stability under all
conditions.
- list the types of surfaces where ABS will not offer a stopping
distance advantage over conventional braking systems.
- name two ways that a driver may deactivate ABS, without
realizing it.
- explain the difference between 4-wheel and 2-wheel ABS.
- demonstrate an appropriate response to ABS in operation.
Overview
Maintaining control of your vehicle is
a key to safe driving. The traction between your rolling tires and the road
surface will impact the amount of control you have in a given situation.
Braking -- whether slowing for a turn or braking for a stop -- can cause a car
to lose rolling traction. This can affect stopping distance and steering
control. Anti-lock brake system (ABS) technology has become available to
maintain rolling traction, offering skid-free stopping and steering
control.
ABS allows the driver to steer his/her vehicle out of potentially damaging situations. The anti-lock brake system is engaged only under potentially dangerous conditions and engages when it detects impending wheel lock. ABS is not engaged under normal braking conditions and it will not impair normal braking actions. The following information is intended for 4-wheel ABS except where noted otherwise.
