During late afternoon hours, traffic volumes can increase as commuters head home, and passing zones or curves may require heightened attention from drivers.

When mutual aid is called, it typically reflects the seriousness of the incident and the need for additional personnel to manage patient care and traffic control simultaneously.

A: Although this crash occurred on a highway, head-on collisions can result from lane departures, distraction, or misjudging distance and speed on two-way roads.
