New Zealand Railways Corporation (General) Regulations 1982

28 Weight, speed, and load limits for bridges
  • (1) The Chief Civil Engineer may from time to time, with respect to traffic using, or passing under, any bridge, fix—

    • (a) the maximum weight for heavy vehicles:

    • (b) the maximum portion of the weight of any heavy vehicle borne on any one axle or group of axles:

    • (c) the maximum speed at which any vehicle may be operated on the bridge:

    • (d) the maximum height of any vehicle or of its load.

    (2) The weight limits or speed limit or height limit fixed with respect to traffic using any bridge shall become effective for the purposes of this regulation as soon as there shall be erected at each end of the bridge a sign indicating the weight limits or speed limit or height limit so fixed.

    (3) The height limit fixed with respect to traffic passing under any bridge shall become effective for the purposes of this regulation as soon as there shall be erected at each side of the bridge a sign indicating the height limit fixed.

    (4) No person shall—

    • (a) operate on or over any bridge any heavy vehicle which exceeds the weight limits for the time being in force and fixed with respect to that bridge pursuant to this regulation; or

    • (b) operate any vehicle on or over any bridge at a speed exceeding the speed limit for the time being in force and fixed with respect to that bridge pursuant to this regulation; or

    • (c) operate on, over, or under any bridge any vehicle that itself or the load thereon exceeds the height limit for the time being in force and fixed with respect to that bridge pursuant to this regulation.

    (5) For the purposes of this regulation the weight of a heavy vehicle shall be deemed to include the weight of any trailer drawn by the heavy vehicle.

    (6) The following provisions shall apply with respect to every such sign which may be in the form of diagram No 4 in Schedule 4 of the Heavy Motor Vehicle Regulations 1974 in addition to the foregoing provisions of this regulation:

    • (a) panel 1 of the sign may show the words Class II, in which case the weight limits which apply to individual axles on Class II roads shall apply on the bridge. Alternatively panel 1 of the sign may show a weight in kilograms in which case the weight shown shall be the weight limit on any one axle on the bridge. If no special axle weight limits are determined, the word Axles and panel 1 may be omitted from the sign, and its height may be reduced accordingly:

    • (b) panel 2 of the sign may show any of the figures 30, 40, 50, 60, 70, 80 or 90 followed by % of Class I, in which case the maximum sum of any 2 or more adjacent axles shall not exceed the stated percentage of the sum of axle weights allowed on Class I roads by tables No 2 and No 3 in Schedule 2 of the Heavy Motor Vehicle Regulations 1974. Alternatively panel 2 of the sign may show a weight in kilograms in which case the weight shown shall be the gross weight limit of any heavy motor vehicle on the bridge. If no special gross weight limits are fixed the word Gross and panel 2 may be omitted from the sign, and its height may be reduced accordingly:

    • (c) panel 3 of the sign shall show the maximum speed limit for heavy motor vehicles in kilometres per hour. If no special speed limit is determined for heavy motor vehicles the word Speed may be omitted from the sign and its height may be reduced accordingly.

    (7) Notwithstanding anything in the foregoing provisions of this regulation, a District Railway Engineer may give written permission for any specified vehicle, being a vehicle the weight of which (whether laden or unladen) exceeds the weight limits fixed with respect to any bridge, to be taken on to or over that bridge subject to such conditions as the District Railway Engineer thinks fit to impose. The permission shall be signed by the District Railway Engineer or by any member of his staff or other person authorised by him in that behalf and may apply to any particular trip or to any number of trips or to a specified period or specified periods and may, at any time, be revoked or amended by any District Railway Engineer.

    (8) No such permission shall prejudice the rights of the Corporation or the controlling authority appointed pursuant to any other Act to recover by legal process reimbursement for any damage done to the bridge during the trip or trips so permitted.

    (9) In any prosecution for a breach of this regulation it shall be sufficient evidence that the weight limits or speed limit or height limit with respect to any bridge had been fixed and were in force in accordance with this regulation if the prosecution proves that at the time when the offence was committed the signs indicating the weight limits, or speed limit, or height limit, or any of them, were in position at each end of the bridge, or at each side of the bridge, as the case may be.

    (10) Every person operating a vehicle under a permission given as aforesaid shall comply with all the conditions of the permission and no person shall operate the vehicle unless the permission is carried therein. The person driving the vehicle shall produce the permission when requested to do so by any authorised officer.
