Transportation Assistance for Individuals with Disabilities Act This bill directs the Department of Transportation (DOT) to establish a grant program for protection and advocacy (P&A) systems to advocate for individuals with disabilities to access transportation. (Each state has a designated P&A system that protects and advocates for the rights of individuals with disabilities.) The bill directs DOT to select 10 P&A systems to receive five-year grants. Grant recipients must submit an annual report documenting the work they have done to address the barriers to accessing transportation for individuals with disabilities. Further, DOT must award one grant annually to a national organization with extensive knowledge of P&A systems to provide training and technical assistance to the systems.
