between the sections for passengers and the rear sections of which is connected to the front section so as to allow rotary movement between the sections.

   ARTICULATED VEHICLE - a combination of 'Prime Mover' and 'Semi-trailer'.

   ASYMMETRICAL TYRE - a tyre which, through 'Tread' pattern or construction, is required to be fitted to a vehicle such that one particular 'Sidewall' faces outwards.

   ATTACHING CLIP - the device shown in Figure 1 of ADR 34/... which is part of the 'Child Restraint' and is designed to be attached to the 'Child Restraint Anchor Fitting'.

   ATTACHMENT BOLT - a standard 5/16 inch 18 UNC - 2A hexagon headed bolt 30 mm in length. The length is measured from the underside of the head to the end of the threaded shank.

   ATTACHMENT SECTIONS - angle or other sections used for attachment of the baseplate, subchassis or sliding subassembly of the 'Fifth Wheel Assembly' to the vehicle chassis.

   AUDIBLE INDICATOR - a device incorporated in a 'Brake Power Unit 35/…' system which indicates to the operator by an intermittent or continuous audible signal that the supply pressure of the working fluid in the system has fallen below a predetermined level.

   AUTOMATED DRIVING SYSTEM - A longitudinal and lateral vehicle control system which is able to cope with all dynamic driving tasks within its 'Operational Design Domain', or will otherwise transition control to a driver.

   Note: An 'Automated Driving System' may also transition control to a driver if/when the 'Operational Design Domain' boundaries are reached
   (e.g. when exiting a motorway).

   AUTOMATIC LENGTH ADJUSTING AND LOCKING RETRACTOR - a retractor incorporating a self-actuating mechanism which automatically locks the retractor at the webbing extension selected by the user.

   AUTOMATIC PIN COUPLING - a 'Coupling' which utilises a vertical pin through a towing eye attached to the 'Drawbar' with a 'Drawbar' eye guidance socket and a self-engaging pin and locking mechanism.

   AUTOMATIC TRANSMISSION - a transmission in which there is no driver-controlled system for disconnecting the drive between the engine and the driving wheels other than the system for selecting gear ratios.

   AVERAGE DECELERATION - the number determined by dividing the square of the initial vehicle speed by twice the stopping distance expressed in compatible units.

   AVERAGE OPERATING PRESSURE - the arithmetic average of the 'Manufacturer's' specified maximum and minimum pressures in the operating pressure range.

   AVERAGE RETARDATION COEFFICIENT - the average braking deceleration, from initial movement of the brake 'Control' to the trailer becoming stationary, expressed as a proportion of the acceleration due to gravity.

   AXIS OF REFERENCE (or "reference axis") - the characteristic axis of the lamp signal determined by the manufacturer of the lamp for use as the direction of reference (H = 0o, V
