What classification is given to a highway incident that results in lane closures for over 1 hour?

A highway incident that results in lane closures for over one hour is classified as a major traffic incident. This classification is critical for several reasons. Incidents that cause significant disruptions, such as extensive lane closures, can lead to severe traffic delays and increased congestion. When an incident's impact on traffic flow is substantial, responders categorize it as major to ensure that appropriate resources are allocated for management and mitigation.

This classification helps in planning responses, such as deploying additional units to clear the scene quickly and managing traffic around the incident area. By recognizing an incident as major, traffic management teams can implement detours, alert drivers through signage, and coordinate with law enforcement and emergency services for a more efficient response.

Other classifications, such as minor or intermediate traffic incidents, typically refer to situations with less impact on traffic flow, such as brief, less severe incidents or minor accidents that can usually be cleared quickly without extensive lane closures. Therefore, understanding the classification is essential for effective traffic management and incident response.
