Crestline Coach Ltd. searched the world to determine the role visibility plays in emergency vehicle collisions and learned that adequate research did not exist that established rules and guidelines for emergency vehicle conspicuity. Crestline developed a system that rates emergency vehicle visibility in daytime and nighttime conditions. The Emergency Vehicle Conspicuity Scoring System (EVCON) is based on rating the use of fluorescent colors, retroreflective sheeting, contrasting colors and pattern. Once this research was completed, Crestline created an emergency vehicle that maximized visibility in all operational conditions. People stare when they see this vehicle. Exactly the response you want when driving an emergency vehicle.
