ADA Signs

 The American Disabilities Act (ADA) came to action in 1992.

It requires all public establishments (except government buildings and churches) to install signage that includes tactile lettering, Grade II Braille, and sometimes, pictograms. The required elements of the sign must be made of “matte, eggshell or other non-glare” materials. This doesn't exclude reflective materials, 

however, the ADA portion of the sign has to be a non-reflective material.
