Police officers are routinely the first to arrive at the scene of traffic accidents, and in some cases may be the only responder. Officers too often become victims themselves at traffic accident scenes as they hasten to assist victims. By following safety protocols, officers can reduce their risk at traffic accident scenes. Officers should collect as much data about the traffic accident as possible from dispatch on the way to the scene. Lighting for day versus night traffic accidents is reviewed and officers are encouraged to call for backup if help is required to properly warn or redirected oncoming traffic. Advice is offered for the safest positioning of patrol cars when they are used to block the scene and protect it from oncoming traffic. By positioning the unoccupied patrol car far enough away and with the wheels turned to the side, it will careen off to the side if it is hit and not strike victims and personnel at the scene. Officers are encouraged to wear a reflective vest and be equipped with a flashlight and a whistle when directing traffic away from an accident scene. Caution should be exercised when approaching victims who crashed their cars while fleeing police pursuit; these victims may continue to pose a danger to officers. Tips are also offered for preserving evidence and allowing access for emergency medical personnel.
