Which feature of a vehicle helps prevent skidding on wet or icy roads?

The traction control system is designed specifically to help prevent skidding on wet or icy roads. This system works by automatically adjusting the power delivered to the wheels to maintain traction, which is crucial when road conditions are less than ideal. When the system detects that one or more wheels are slipping, it can reduce engine power or apply the brakes selectively to ensure that the vehicle maintains grip on the road surface.

In contrast, power steering mainly enhances the driver's ability to steer the vehicle comfortably and does not directly impact traction on slippery surfaces. The anti-lock braking system (ABS) does play a role in vehicle stability during braking, as it prevents wheel lock-up and helps maintain steering control under hard braking conditions. However, it doesn’t actively manage wheel slip while accelerating, which is where the traction control system shines. Manual transmission relates to how a vehicle is operated but does not provide features aimed at enhancing traction during adverse road conditions.
