Curb painting and signs can be used individually or together to help convey a specific message to drivers. A painted curb means that you must follow special rules. Painted curbs are often located around a school to inform drivers where parking and stopping are allowed or prohibited. The color on the curb typically means:
White (or no color):
Parking allowed, unless restricted or limited by signs.
Parking for the disabled only. Motorists must have a disabled person parking placard (typically hanging on the rear view mirror) or disabled person or disabled veteran license plate.
Parking allowed for a short time. The time is usually shown on a sign next to the green zone, or may be painted on the curb. Green curb can also be used for student loading zones, if accompanied by the appropriate signs.
Stop only long enough to load or unload passengers – no longer than posted. Drivers are usually required to stay with their vehicle.
No stopping, standing, or parking. A bus may stop at a red zone marked for buses. Red is also used to designate fire lanes at schools or “No Parking” areas.
