Without limiting the general duty to accept and convey passengers, the driver of an accessible taxicab must respond to a call for service from a person with a disability who uses a wheelchair or scooter and who is located in the same geographic zone before accepting any other call. Each licensee must dispatch an accessible taxicab to a person with a disability who uses a wheelchair or scooter before assigning the accessible taxicab to any other passenger. (2004 L.M.C., ch. 27, § 1.)
