How can you tell if a street is one-way?

Identifying whether a street is one-way involves looking for specific signage and visual clues. One-way signs are the most direct indicator, as they explicitly confirm that all vehicles must travel in the direction indicated by the arrow on the sign. Additionally, observing the direction of parked vehicles can provide guidance; if all the cars are parked facing the same way, that's a strong indication that traffic flows in that direction.

While stop signs are important for managing intersections, they do not provide information regarding the flow of traffic on the street itself. Similarly, traffic lights are designed primarily for controlling the movement at intersections rather than indicating the directional flow of a roadway. Street name changes can sometimes happen on one-way streets, but they are not a reliable indicator of directional traffic flow.

Therefore, the most effective and immediate way to determine if a street is one-way is by looking for one-way signs and the orientation of parked vehicles.
