Final answer:
Turns and curve signs warn drivers of potential turning or curving roads by providing information about the direction of turns and curves on the road ahead.
Step-by-step explanation:
Turns and curve signs warn drivers of potential turning or curving roads. These signs provide important information to drivers, indicating the direction of turns and curves on the road ahead. For example, a right turn sign alerts drivers to upcoming right turns, while a winding road ahead sign informs them to be prepared for a road with multiple curves. These signs help drivers navigate safely and adjust their speed accordingly.
