Do not move the injured or the deceased

When there are injured people, they must not be moved or displaced — unless it is strictly necessary to prevent their condition from worsening, or they have ended up in a place of imminent danger.

When there are deceased people, the bodies must not be moved until the competent authority so orders. Fuente: Reglamento de la Ley de Tránsito y Vialidad del Estado de Yucatán, Artículo 399.
