According to the Manual on Uniform Traffic Control Devices (MUTCD), a major traffic incident has an expected duration of what?

A major traffic incident, as defined by the Manual on Uniform Traffic Control Devices (MUTCD), is one that is expected to last more than 2 hours. This duration is significant because it indicates that the incident is likely to cause substantial disruption to traffic flow, necessitating special traffic management considerations and possibly the deployment of resources to effectively manage the situation.

Incidents lasting longer than this threshold may warrant additional safety measures, including the use of advanced traffic control measures, warnings for motorists, and potentially the rerouting of traffic. Understanding this time frame helps in preparing and responding effectively to traffic incidents, ensuring safety for both motorists and responders while minimizing congestion.
