Alberta Class 3 Drivers License Practice Exam

What happens to traction once the tires begin to skid?

Traction increases Traction remains the same Traction decreases Traction increases then decreases

Correct Answer:

Traction decreases

Explanation:

Traction is the grip between the tires and the road. When tires roll without slipping, the friction is static and provides the maximum grip. Once the tires start to skid, they slide across the road, and the friction becomes kinetic, which is weaker than static. That drop in friction means the tires lose grip, so traction decreases. Road conditions like wet or icy surfaces make this even more pronounced, increasing stopping distances and reducing steering control. Systems that prevent wheel lock help, but once a skid begins, easing braking to let static friction reestablish is how you regain traction.
