On Thursday, the U.S. government filed a lawsuit against Uber, alleging that the ride-sharing service has breached federal laws by discriminating against passengers with disabilities.

The complaint, submitted in federal court in San Francisco, claims that Uber drivers frequently refuse to transport disabled riders, including those accompanied by service animals or using wheelchairs.

Additionally, the department stated that Uber and its drivers unlawfully impose cleaning fees for service animals on riders denied service and also charge cancellation fees.

Some drivers are reportedly dismissing legitimate requests, such as humiliating persons with disabilities or preventing passengers with mobility challenges from sitting in the front seats.

According to the Justice Department, “Uber’s discriminatory actions have inflicted significant financial, emotional, and physical harm on individuals with disabilities,” violating the Americans with Disabilities Act.

In response, Uber stated that it disputes the allegations and is dedicated to enhancing access and the overall experience for riders with disabilities.

Uber further asserts that riders utilizing guide dogs or requiring other assistance “deserve a safe, respectful, and welcoming experience with Uber. A complete stop.”

The complaint outlines 17 instances of alleged misconduct involving Uber.

One instance involves JE, a seven-year-old amputee from the Bronx, New York, who reportedly faced refusal from an Uber driver after attending his brother’s birthday party due to his wheelchair.

Another case highlights Jason Ludwig, a Gulf War veteran with a service dog, who was denied a ride to Norfolk Airport in Virginia, causing him to miss his flight and return to Yarmouth, Massachusetts, after 16 hours of travel.

Jeff Clark, a third rider from Mount Laurel, New Jersey, claims that four drivers canceled their ride in Philadelphia within 17 minutes.

The lawsuit aims for an injunction to prevent further violations of the ADA, along with demands for improvements in Uber’s practices and training, financial compensation, and civil penalties.

A spokesperson for the Department of Justice was not available for immediate comment.
