What is the prima facie speed limit for highways numbered by the state or US outside urban areas?

The prima facie speed limit for highways numbered by the state or the U.S. outside urban areas is set at 70 mph. This speed limit is applicable under normal driving conditions and reflects the established guidelines for safe and efficient travel on these types of roadways.

In many jurisdictions, the rationale for a higher speed limit on highways is based on the design and intended use of these roads, which are typically built for faster-moving traffic and have fewer intersections and stoplights compared to urban roads. As a result, drivers can safely maintain higher speeds while traveling on highways outside of city environments, where the risk of pedestrian crossings and slow-moving traffic is lower.

Understanding this speed limit is crucial for law enforcement and drivers alike to ensure compliance with traffic laws, maintain road safety, and facilitate smooth vehicular movement on major highways.
