Roadway Signs, Striping, and Curb Painting

Roadway signs are devices used to help inform the motoring public what to do and what to expect while traveling through Corona. Stop signs are installed with great care for the safety of the motoring and pedestrian public. Signs are only as effective as the people that follow them, so please be mindful of traffic signs and obey them.

Roadway striping is used to keep vehicles in their lanes and to show them where they are allowed to perform turns and other maneuvers safely. Corona is a proactive city when it comes to keeping striping current and well maintained. If you see striping that is faded, missing or is confusing, please report it.

Curb painting restricts parking and stopping on public streets to maintain safe traffic conditions. If you have any questions or concerns about roadway signs, striping, or curb painting, please report it to Public Works.
