This section includes example methods for determining lighting warrant for roadway lighting systems. AASHTO provides warranting methods for continuous freeway lighting, complete interchange lighting, and partial interchange lighting. Other methods for collector/arterial/local roads as well as for intersections have been included in this section for information.

It is important to note that warrants do not represent a requirement to provide lighting. Satisfaction of a lighting warrant shall not in itself require the installation of a lighting system.
