Thousands of signs and other inventory items, equipment,facilities, and staff are all dedicated to the installation and maintenance of devices and markingscritical to the safety and convenience of the traveling public.General requirements and responsibilities for these activities are contained in the Manual forUniform Traffic Control Devices (MUTCD) and in the Code of Iowa.
