What factor is crucial when navigating turns in poor weather conditions?

Decelerating before entering a turn is crucial in poor weather conditions because it allows for better control of the vehicle. In situations such as rain, snow, or ice, the road surface can become slippery, reducing tire traction. By slowing down prior to the turn, a driver minimizes the risk of losing control and enhances their ability to navigate the curve safely. Slower speeds also provide more time to react to changes in the road or unexpected obstacles that may arise during the turn. This practice is essential not only for the driver's safety but also for the safety of others on the road.

Maintaining a high speed, making abrupt maneuvers, or increasing the use of the accelerator in such conditions would increase the likelihood of skidding or accidents, as they can lead to a loss of traction and control. Therefore, decelerating is the best strategy to ensure a safe turn in adverse weather.
