Definition & Meaning of "one-way street"

What is a "one-way street"?

A one-way street is a road or street where traffic is allowed to travel in only one direction. Vehicles are required to follow the direction indicated by signs or markings, and driving in the opposite direction is not permitted. One-way streets are commonly used in cities to help manage traffic flow, reduce congestion, and increase safety by minimizing the risk of accidents. These streets are often narrower or located in busy areas, where controlling the direction of traffic makes travel more efficient and orderly.
