Although the blue-signed handicapped parking spaces are legally restricted, there are no laws about who is allowed to use a restroom or stall designated for the handicapped, says Thomas Schmokel, a consultant who helps businesses comply with the Americans with Disabilities Act. If there are disabled people around, it’s impolite to use the handicapped restroom or stall ahead of them, but if not, you can use whichever one you want. “If you like more room or need a place to hang your newspaper, it’s fine,” Schmokel says.
