San Francisco’s luxury bus company Leap Transit was ordered on May 11 to stop operating by the California Public Utilities Commission because the start-up company did not have the proper permits.

The cease-and–desist order came as Leap was completing the state’s permitting process. Leap had received a preliminary license until the state could issue an official permit, but failed to provide proof of insurance, complete mandatory bus inspections, conduct drug and alcohol screenings for drivers, or ensure wheelchair accessibility.

Leap disputes the CPUC’s decision. “We went out of our way to work with the city and state so that we can operate fair and square,” says Leap CEO Kyle Kirchhoff. “In the meantime we are able to operate legally and in our opinion, are helping people get out of private cars and back onto mass transit, which I think we can all agree is beneficial to the city.”

The company came under fire from disability advocates in March after it purchased wheelchair-accessible buses and then removed all of the lifts and tie-downs. “Leap actually took vehicles that were accessible and rendered them inaccessible, which is both a violation of the Americans with Disabilities Act’s requirement for maintenance of accessible features and also a terrible slap in the face of the disability community,“ says Marilyn Golden, a senior policy analyst with the Disability Rights Education and Defense Fund.

Leap answered its critics with a promise to restore full accessibility on the bus in its fleet that still had a working lift.

Private shuttles like Leap, are a trendy alternative to public transportation. Leap fares are $6 and rides can be arranged by smartphone app. Each bus offers amenities such as USB hookups, comfortable seating and gourmet beverages.
