to be driven simultaneously, including vehicles where the drive to one 'Axle' can be disengaged; and
            2.       There is at least one differential locking mechanism or at least one mechanism having a similar effect; and
            3.       They can climb a 25 per cent gradient calculated for a solo vehicle.

 1.                                  Omnibuses with a 'Gross Vehicle Mass' exceeding 12 tonnes and heavy goods vehicles
     1.                            Category ME vehicles with a 'Gross Vehicle Mass' exceeding 12 tonnes, and category NC vehicles are considered to be 'designed for off-road use' if all of the following criteria are satisfied:
            1.       All wheels are driven, except where applicable, when the drive to one 'Axle' is disengaged; and
            2.       There is at least one differential locking mechanism or at least one mechanism having a similar effect; and
            3.       They can climb a 25 per cent gradient calculated for a solo vehicle; and
            4.       At least four of the following six criteria are satisfied:
                  1.         The 'Approach Angle' is at least 25°;
                  2.       The 'Departure Angle' is at least 25°;
                  3.    The 'Breakover Angle' is at least 25°;
                  4.     The 'Ground Clearance' under the front 'Axle' is at least 250 mm;
                  5.       The 'Ground Clearance' between the 'Axles' is at least 300 mm;
                  6.     The 'Ground Clearance' under the rear 'Axle' is at least 250 mm.

 2.                                  Load and checking conditions
     1.                            The measurements referred to in clause 2.1 of this appendix are determined with the vehicle loaded to its 'Gross Vehicle Mass'.
     2.                            When measuring the 'Approach Angle' and the 'Departure Angle', no account is taken of underrun protective devices.

 3.                                  Example Illustrations
     1.                            Example illustrations of 'Approach Angle', 'Departure Angle' and 'Breakover Angle' are shown in Figures 1 to 3. In all cases, the lines shown in contact with tyres are tangent to the 'Static Loaded Tyre Radius' arc(s).

APPENDIX C

      Alternative lane markings

 1.                                  Australian visible lane marking identification
     1.                            For the purpose of the tests to clauses 6.4 to 6.5 of this standard, and paragraph 6.5 of Appendix A, the test lane width must be greater than 3.5 m.
         1.                     The lane width shall be measured as per the definition of lane width in Annex 3 to Appendix A of this rule above.
     2.                            The visible lane markings identified in Table 2 below are all white.
