What is the primary purpose of the chaflan at an intersection?

The primary purpose of the chaflan at an intersection is to allow for vehicle turning movements. A chaflan is typically a triangular or angled portion of the roadway designed to facilitate the smooth and safe turning of vehicles, particularly at intersections where angles may be sharp. By providing additional space at the corners, chaflans help prevent vehicles from hitting curbs and improve the overall maneuverability for larger vehicles such as trucks. This design element is crucial in enhancing safety and efficiency during turning maneuvers, making it easier for drivers to navigate intersections without encroaching into opposing lanes of traffic.
