You’ve seen these parking signs everywhere and you may just take it for granted that these have been around forever. Well, guess what. These signs have not been around for too long, and the mandatory use of these signs on mandatory assigned parking spaces began just a couple of decades ago. The presence of these signs in all parking facilities in the US is due to the creation of the ADA, which is a law that helps promote equality among everyone.
The law is aimed at giving people with disabilities equal rights with everyone, and this is pretty evident with the name of this law – Americans with Disabilities Act. When it comes to the parking signs that are made to show people where parking spots for people with disabilities can be found, you can easily discern these from other spots due to the telltale wheelchair symbol on them. This symbol is called the ISA or International Symbol for Accessibility.
