What does a one-way street sign indicate?

Answer: B — Traffic must travel in the direction indicated by the sign

A one-way street sign indicates that traffic must travel in the direction indicated by the sign. This means that all vehicles on that street are required to move in the specified direction, ensuring safety and orderly traffic flow. Drivers approaching a one-way street must be aware that entering the street from the opposite direction can lead to dangerous situations, as it may result in head-on collisions. In contrast, other options do not accurately describe the implications of a one-way street sign. The sign does not give permission for traffic to flow in any direction, nor does it imply anything about parking regulations or U-turn restrictions. The primary purpose of this sign is to direct all traffic consistently in one direction to minimize confusion and enhance road safety.
