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, scooter, and/or other mobility devices, or individuals who have limited mobility that are located before accepting any other call. Each licensee must dispatch an accessible taxicab to a person with a disability who uses a wheelchair, scooter, and/or other mobility devices, or has limited mobility before assigning the accessible taxicab to any other passenger.
