constitute an obstruction;
18.4.1.1.2.              in the case of Group II 'Visual Indicators' the steering wheel rim and its supporting arms and attachments thereto shall not constitute obstructions.
18.4.1.2.                    Any object which represents an obstruction to any single eye position within the terms of Clause 18.4.1.1 shall have no surfaces, in the line of sight to the 'Visual Indicator', which present a metal finish with a 'Specular Gloss' exceeding 40 units when measured by the 20 degree geometry method of ASTM Standard D523 62T "Specular Gloss" June 1962 or ASTM Standard D523-85T-"Specular Gloss", September 1985.
18.4.1.3.                    All indicator lamp 'Visual Indicators' shall either be 'Totally Visible', or an area of not less than 18 square millimetres with dimensions such that a 2 mm diameter circle is totally enclosed within the area, shall be 'Totally Visible' when viewed from each single eye position located by the '95th Percentile Eye Ellipses'. The obstruction exemptions provided for in Clause 18.4.1.1 shall also be applicable to this Clause.
18.4.1.4.                    In the case of a motor vehicle provided with a steering wheel capable of axial and vertical adjustments, it shall be demonstrated that for any eye position located by the '95th Percentile Eye Ellipses', there is at least one steering wheel position where the requirements of Clauses 18.4.1.1 to 18.4.1.3 are complied with.
18.4.2.                          The vehicle speed indicating element shall be of such colour or contrast as to differentiate it from the viewed background.
18.4.3.                          All 'Visual Indicators' other than indicator lamps shall be provided with variable intensity when illuminated.

         Note: A switch which provides a means of varying the illumination to 'Visual Indicators', but is not integral with the on/off control for the illumination of 'Visual Indicators' is acceptable as a means of providing variable intensity illumination to 'Visual Indicators'. It shall be acceptable for the intensity control to have not less than 2 levels of adjustment other than an "off" position provided that each position results in a substantially different level of illumination to 'Visual Indicators'.

18.5.                                SPEEDOMETERS AND ODOMETERS (ALL VEHICLES)
18.5.1.                          Speedometers
18.5.1.1.                    Unless otherwise 'Approved', every vehicle shall be fitted with a speedometer which shall:
18.5.1.1.1.              indicate vehicle speed only in kilometres per hour and
18.5.1.1.2.              indicate the actual vehicle speed, for all speeds above 40 km/h, to an accuracy of ± 10 percent
18.5.1.2.                    The speedometer shall be installed so that its indication is readily visible to the driver when seated in the normal driving position.
18.5.2.                          Odometers
18.5.2.1.                    Every vehicle other than L-group vehicles shall be fitted with an odometer which shall:
18.5.2.1.1.              indicate distance travelled in one kilometre units (or less) from 1 to 999,999 kilometres; and
18.5.2.1.2.              indicate the actual distance travelled by the vehicle to an
