The term used by TXDOT for a traffic incident lasting more than 4 hours, which often involves fatalities, is classified as a major incident. This classification reflects the severity and complexity of such incidents, as they not only disrupt traffic for an extended period but also typically require significant resources from emergency services. Major incidents can lead to complex situations including multiple vehicle collisions, hazardous material spills, or serious accidents that require comprehensive investigation and management.

In contrast, minor incidents would refer to situations that are less serious, such as minor collisions that do not result in injuries or fatalities. Intermediate and significant incidents may suggest elevated levels of disruption or resource involvement but do not specifically denote the extended duration or the critical nature associated with a major incident. Therefore, understanding the classification of incidents is vital for effective incident management and response in the field of transportation and traffic control.
