The Justice Department is suing Lyft, alleging the rideshare company discriminated against passengers with disabilities, including those who use service animals and mobility devices such as wheelchairs.

The lawsuit, which was filed Monday in the U.S. District Court for the Northern District of California, is seeking $53 million in damages for individuals with disabilities, who the department says experienced discrimination and submitted complaints to Lyft or the Justice Department.

Big picture view: The department alleges Lyft violated Title III of the Americans with Disabilities Act of 1990 (ADA), which prohibits private transportation companies, such as Lyft, from discriminating based on disability.
