Federal law requires public areas to have designated parking for the disabled, and it outlines rules regarding the identification and marking of these parking spots as well as the visibility of handicapped parking signs at the reserved spots, according to My Parking Sign. State and local governments may institute additional laws as long as they meet or exceed the requirements of the federal law.
The Americans with Disabilities Act is the federal law that outlines the requirements for disabled parking areas, states My Parking Sign. Handicapped parking signs must have the international symbol of accessibility, which is picture of a person in a wheelchair against a blue background. The ADA requires these signs to be visible from the driver's seat of a car, in view of the parking area and placed at least 60 inches above the ground, so that parked cars and other obstructions do not block the view. Van-accessible parking must have additional text below the accessibility symbol to assist in the location of these spaces. The ADA also contains rules regarding the required number of disabled parking spots in relation to the total number of parking spaces, their size and location, and the width of the access aisle next to them.
