What does this sign mean regarding turning?

The sign indicating "No right turn" provides clear guidance to drivers that turning right at the upcoming intersection is prohibited. This is critical for maintaining traffic flow and ensuring safety at intersections where right turns might conflict with oncoming traffic or pedestrians.

Signs that indicate "Keep right," "No U-turn," and "Left lane must turn left" serve different purposes. For example, "Keep right" directs drivers to stay in the right lane, affecting lane discipline rather than turning actions. "No U-turn" clearly prohibits a specific type of turn entirely, whereas "Left lane must turn left" indicates lane usage rather than restrictions on turning.

Understanding the meaning of such signs helps drivers navigate intersections safely and comply with traffic regulations effectively.
