What is most likely to decrease your vehicle’s effective steering?

Wet road conditions are indeed likely to decrease your vehicle's effective steering. When roads are wet, the friction between the tires and the pavement is reduced, which can cause the vehicle to slide or hydroplane. This decrease in traction makes it harder for the driver to control the vehicle's direction and respond effectively to steering inputs. As a result, steering becomes less effective, leading to potential difficulties in navigating corners or avoiding obstacles.

In contrast, proper tire alignment helps ensure that the tires make optimal contact with the road, enhancing steering precision. Cold weather, while it can affect tire pressure and handling, does not directly diminish steering effectiveness in the same manner as wet conditions. Lastly, clear visibility is crucial for safe driving but does not influence the mechanical aspects of steering itself.
