What does white line on sidewalk mean?
WHITE LINES painted on the pavement indicate traffic traveling in your direction. Broken White Line: you may change lanes if it is safe to do so. Solid White Line: requires you to stay within the lane and also marks the shoulder of the roadway. YELLOW LINES mark the center of a two-way road used for two-way traffic.
Curb paint and signs can be used individually or together to help convey a specific message to drivers.
