ADA Compliance for Detectable Warnings
ADA Detectable warnings are designed to help millions of Americans with low or no vision safely navigate roads and transit areas, and are required by law to meet specific standards.
In 1991 the USDOT and USDOJ developed legal regulations from the Americans with Disabilities Act. In these guidelines, the requirements for the installation of detectable warnings were specified for sidewalks, street crossings and curb ramps, hazardous vehicular ways, and transit platform edges for the safety of visually impaired citizens.
TekWay High-Performance ADA Systems uphold the fullest compliance, including ADA standards of sizes and colors. Aesthetically pleasing domes are available in almost all natural and federal colors, sizes, dome spacing, and shapes.
