Last week the Justice Department sued ride-sharing service Uber over allegations they overcharge people with disabilities, and asked the US District Court in San Francisco to order the company to comply with a federal law protecting the disabled from discrimination.

When booking an Uber, the cost of the ride is available on the app screen, however, if it takes a longer than two minutes to actually get into the car — Uber adds a “wait-time fee”.

The Justice Department’s lawsuit alleges that this policy (a practice begun in 2016) discriminates against people with disabilities, in violation of the Americans with Disabilities Act, and says that disabled people such as the blind, or those who use wheelchairs or walkers, need more than two minutes to get into an Uber car.

“People with disabilities deserve equal access to all areas of community life, including the private transportation services provided by companies like Uber,” said Assistant Attorney General Kristen Clarke for the Justice Department’s Civil Rights Division in a statement.

“This lawsuit seeks to bring Uber into compliance with the mandate of the Americans with Disabilities Act while sending a powerful message that Uber cannot penalize passengers with disabilities simply because they need more time to get into a car.”

The department is asking the court to order Uber to modify its wait time fee policy and pay monetary damages to those subjected to illegal fees.
