A HAWK beacon (high-intensity activated crosswalk beacon) is a traffic control device used to stop road traffic and allow pedestrians to cross safely. It is officially known as a pedestrian hybrid beacon. The purpose of a HAWK beacon is to allow protected pedestrian crossings, stopping vehicular traffic only as needed. The HAWK beacon is a type of traffic control alternative to traffic control signals and/or where an intersection does not meet traffic signal warrants.[1]: 509
A HAWK beacon is used only for marked crosswalks. A similar hybrid beacon, called "emergency-vehicle hybrid beacons" are allowed at driveways of emergency service buildings such as fire stations.[1]: 513–515
