In case of several claims for damages arising out of a single accident involving a vehicle, the claims of pupils and school personnel, excluding driver when not a pupil, shall be first satisfied. In no event, except where approved self-insurance has been provided pursuant to subsection D of § 22.1-190, shall school funds be used to pay any claim or judgment or any person for any injury arising out of the operation of any such vehicle. The locality or school board may be sued alone or jointly with the driver, provided that in no case shall any member of a school board be liable personally in the capacity of school board member solely.
