Traction is needed to maintain directional control. You need traction in order to:

Explanation:
Traction is the grip between the tires and the road that lets you control the vehicle. You need that grip for accelerating, turning, and braking. When you accelerate, you must transfer engine power to the road; insufficient traction causes wheel spin and loss of forward motion. When you turn, you rely on lateral grip to follow the intended path; without traction the tires will slide and you can’t steer effectively. When you brake, you need friction to slow the vehicle; slipping tires mean longer stopping distances or a skid. Because traction is required for all three actions, you need traction for accelerating, turning, and braking. In wet or icy conditions, this becomes even more crucial.
