Louisiana Revised Statutes Tit. 17, § 493.1. Filling route vacancies

B. A substitute operator shall not be used to fill a route vacancy except as provided in R.S. 17:500(C)(2)(b) and (c).

C. Only if a city or parish school board is required, in filling a vacant route pursuant to Subsection A of this Section, to bear an increase in unreimbursed costs for nonpassenger miles over those attributable to the previous operator who vacated the route, may a school system select an operator to fill the vacant route on a different basis.

D. Notwithstanding any provision of this Section to the contrary, whenever a school bus operator owning his own bus retires, a route shall be offered first to any person meeting the requirements of the school board who is willing to acquire the bus of the retiring operator by a method which guarantees that the operator receives full appraised value for his bus using regularly accepted appraisal methods to determine fair market value. The provisions of this Subsection shall be applicable only when the bus owned by the retiring operator has been manufactured within a period of five years immediately prior to the operator's retirement and the operator is retiring due to a documented physical disability.
