How can you identify that a road is a one-way street?

Answer: B — Signs will be present indicating it is one way, and vehicles will all be traveling in the same direction

The identification of a one-way street is primarily accomplished through specific signage and the direction of traffic flow. One-way streets are typically marked by signs that explicitly indicate the street's designation. Additionally, the visual observation of vehicles moving uniformly in one direction reinforces the indication of a one-way street. This dual confirmation – both through signage and the behavior of traffic – is crucial for drivers to navigate safely and efficiently. Other options, while they may describe features of a street, do not reliably indicate whether a street is one-way. For instance, a one-way street can be of various widths, not necessarily narrower than other streets. The presence or absence of parking signs does not provide relevant information about the street direction either. Lastly, while flashing yellow streetlights convey important information to drivers, they do not specifically indicate the direction of traffic flow on a street. The combination of clear signage and observed traffic direction is the most effective way to determine if a road is one-way.
