Montana Title 20. Education § 20-10-106. Determination of mileage distances

(1) The distance in mileage shall be measured by a vehicle equipped with an accurate odometer.

(2) A representative of the applicable district and a parent or guardian of the child to be transported shall be present when the distance is measured.

(3) The measurement shall begin 6 yards from the family home and end 6 yards from the entrance of the school grounds closest to the route.

(4) The route traversed for the measurement shall be the route designated by the trustees, except that the route shall be reasonably passable during the entire school fiscal year by the vehicle that provides the child's transportation. In determining reasonable passage, a route may not be disqualified because it is impassable during temporary, extreme weather conditions such as rains, snow, or floods.
