Which is a recommended caution on narrow or winding roads?

The recommended caution on narrow or winding roads is to slow down regardless of familiarity. This is essential for several reasons. First, narrow or winding roads often have limited visibility and sharp turns, which can make it difficult to judge the road conditions, potential hazards, and the speed of vehicles approaching from the opposite direction. Reducing speed allows for better reaction time and control of the vehicle, enhancing safety for both yourself and other road users.

Additionally, even if a driver is familiar with the route, conditions can change due to factors like weather, debris, or unexpected obstacles. Slowing down provides the necessary time to react to these changes safely. It promotes the principle of defensive driving, where being cautious helps to mitigate risks while navigating challenging driving environments.
