Retroreflectivity of Traffic Signs and Pavement Markings

In various cities throughout the state of California, some signs and pavement markings are difficult to see during the day, and even more so at night. The California Manual on Uniform Traffic Control Devices (CA MUTCD) addresses maintaining minimum retroreflectivity of signs, but at the moment, there are no similar requirements for minimum standards for pavement markings. While there are no federally required minimum levels of retroreflectivity for these markings, Authority members are advised to include both signs and pavement markings in their street inspection and maintenance process. The Authority will notify members when the CA MUTCD is updated to include information on minimum pavement marking retroreflectivity. For questions on this topic, members can contact their assigned risk manager.
