What does a no entry sign mean?

A no entry sign clearly indicates that the driver is not allowed to enter that specific road or area. This sign serves to enhance safety by preventing vehicles from accessing roads where entry is prohibited, such as one-way streets against traffic or restricted zones. Observing this sign is crucial for maintaining proper traffic flow and ensuring the safety of all road users. The rules surrounding a no entry sign are strict, and compliance is important to avoid confusion and potential accidents. While other options might suggest different levels of access, they do not capture the absolute prohibition indicated by the no entry sign, which is focused on preventing entry altogether.
