The objective of this study was to analyse the use of lights and siren (L&S) during transport to the hospital by the prehospital severity status of the patient and the time saved by the time of day of the mission. ⋯ At present, the use of L&S seems questionable given the severity status or NACA score of transported patients. Our results should prompt the implementation of more specific regulations for L&S use during transport to the hospital, taking into consideration certain physiological criteria of the victim as well as time of day of transport.
