65.1.                                DEFINITIONS
65.1.1.                          Refer to Vehicle Standard (Australian Design Rule Definitions and Vehicle Categories) 2005.
65.1.2.                          'Set Speed' - the maximum road speed specified in clause 65.5.
65.2.                                MAXIMUM ROAD SPEED LIMITING
         The maximum road speed capability shall not exceed the maximum road speed specified in clause 65.5 as determined in accordance with the requirements of:
65.2.1.                          clause 65.6; or
65.2.2.                          clause 65.3; or
65.2.3.                          clause 65.4 and clause 65.6.

65.3.                                MAXIMUM ROAD SPEED LIMITED BY GEARING

         The maximum road speed capability shall be limited by selection of drive train gearing calculated by the formula:

         where:

         L = the engine manufacturer's rated engine speed above which the engine governing system begins to substantially reduce power;

         A= the overall gear reduction between engine and drive wheels giving highest road speed; and

         M= the tyre revolutions per kilometre determined from Table 1 (shown below), or as determined by the 'Administrator' for tyres not listed, which gives the standard number of revolutions per kilometre.

65.3.1.                          In the case of vehicles where the maximum road speed capability is determined by gearing, the engine manufacturer's rated engine speed shall be permanently shown on a plate affixed to the engine.

65.4.                                MAXIMUM ROAD SPEED LIMITED BY ROAD SPEED GOVERNOR
         The maximum road speed capability shall be controlled by the use of a road speed governor in accordance with the following:
65.4.1.                          The maximum road speed setting must
