What does a "no left turn" sign mean?

A "no left turn" sign clearly indicates that turning left at the specified intersection is prohibited. This regulation is typically put in place for various reasons, such as maintaining traffic flow, ensuring the safety of drivers and pedestrians, or managing congestion in certain areas. When a driver sees this sign, they must continue straight or make a right turn instead, complying with the traffic laws in that location. Understanding this sign is crucial for safe driving and adherence to road rules.

The other options introduce scenarios that would not be indicated by a standard "no left turn" sign, which specifically focuses solely on prohibiting left turns without any exceptions or conditions.
