What do warning signs indicating curves or turns provide?

Warning signs indicating curves or turns are designed to alert drivers to changes in the road ahead, particularly where the road might change direction. The primary purpose of these signs is to provide drivers with advanced notice, allowing them time to adjust their speed appropriately before approaching the curve or turn. This is crucial for maintaining control of the vehicle and ensuring safety, as curves can vary in sharpness and difficulty.

While some warning signs may incorporate information about speed limits or the nature of the road ahead, the main focus is on giving drivers sufficient time to reduce their speed. This proactive measure helps prevent accidents and improves overall driving safety, particularly in unfamiliar or potentially hazardous conditions. By understanding this concept, drivers can better prepare themselves for navigating curves or turns safely.
