  The board may make necessary rules to provide for the policing, control, and regulation of traffic and parking of vehicles and bicycles on school grounds. The rules may provide for the use of institutional roads, driveways, and grounds; registration of vehicles and bicycles; the designation of parking areas; the erection and maintenance of signs designating prohibitions or restrictions; the installation and maintenance of parking control devices; and assessment, enforcement, and collection of reasonable penalties for the violation of the rules.
  Rules made under this section may be enforced under procedures adopted by the board. Penalties may be imposed for violation of the rules, including, but not limited to, a reasonable monetary penalty. The rules made under this section may also be enforced by the impoundment of vehicles and bicycles for violation of the rules. The board shall establish procedures for the determination of controversies in connection with the imposition of penalties. The procedures must require giving notice of the violation and the penalty prescribed and providing the opportunity for an administrative hearing.
  The board may contract with a city or county to enforce rules made under this section by ordinance of the city or county, and shall consult with local government transportation officials to ensure that rules made pursuant to this section are not in conflict with city or county parking and traffic ordinances.
