How do you know if a road is one-way?

Answer: B — Check for one-way signs and the direction of traffic flow

Identifying a one-way road primarily involves looking for one-way signs that clearly indicate the road's traffic direction. These signs are placed at strategic locations, such as intersections, to ensure that drivers are aware of the rules specific to that roadway. Additionally, observing the direction of the traffic flow can provide immediate clues, as vehicles going in the same direction confirm that it is a one-way street. While speed limit signs, GPS systems, and bike lane markings can offer valuable information about road use, they do not specifically indicate whether a road is one-way. Speed limit signs inform you of the maximum legal speed but do not denote traffic direction. GPS systems can assist in navigation but may not always provide real-time updates about road conditions or signage. Bike lane markings indicate areas designated for bicycles and, while they can coexist with one-way streets, do not serve as indicators of the traffic flow direction. Thus, confirming the presence of one-way signs and observing the flow of vehicles are the most reliable methods for determining if a road is one-way.
