The Department of Justice filed a lawsuit against rideshare company Lyft, accusing it of discriminating against passengers with disabilities by repeatedly denying rides, charging improper fees and failing to make accommodations.

The lawsuit, filed in the U.S. District Court for the Northern District of California on Monday, accused Lyft of denying service to "hundreds, likely thousands," of individuals with disabilities who travel with service animals or who use wheelchairs or other mobility devices, the suit said.

Lyft allegedly receives "thousands of complaints each year alleging disability-based discrimination," but the company refuses to modify its policies, practices or procedures "to avoid discriminating against riders with disabilities," the suit alleges.
