What is the primary function of traction control in vehicles?

The primary function of traction control in vehicles is to maximize traction while the vehicle is in motion. Traction control systems work by monitoring the wheel speeds and can apply the brakes to individual wheels or reduce engine power when it detects that a wheel is spinning faster than the others, which typically occurs during slippery conditions or rapid acceleration. By managing the wheel slip, traction control helps maintain better grip on the road, enhancing vehicle safety and performance, especially in adverse weather conditions. This technology is particularly valuable in maintaining control and preventing skidding, thereby allowing the vehicle to accelerate safely without losing traction.

Other options, while they may relate to vehicle performance in some contexts, do not capture the essential role of traction control, which is to ensure maximum contact between the tires and the road surface.
