device that transmits the 'Control Signal' from the towing vehicle to the first other device, or between other devices on the trailer as a boosted or relayed signal not involving significant amounts of 'Stored Energy' transfer. (Often called the service line in the case of compressed air 'Brake Systems').

   CONTROL LINE 35/...- the device that transmits the 'Control Signal' to the 'Coupling Head'. (Often called the service line in the case of compressed air 'Brake Systems').

   CONTROL SIGNAL - means the signal that is provided by the towing vehicle to the trailer for control of the 'Service Brake System' in normal operation.

   CONTROL SYSTEM - means all the 'Brake Devices' between the trailer 'Brake System' couplings (supply and control) and the 'Brakes' actuators, including front coupling hoses for trailers with drawbars.

   CONVERTER DOLLY - a 'Pig Trailer' with a 'Fifth Wheel Coupling', designed to convert a 'Semi-trailer' into a 'Dog Trailer'.

   CONVEX MIRROR - means a mirror having a curved reflective surface whose shape is the same as that of the external surface of a section of a sphere.

   CORD - the strands forming the 'Plies' in the tyre.

   CORD SEPARATION - 'Cord' parting away from adjacent rubber compounds.

   CORRECTIVE ACTION - action, other than 'Scheduled Maintenance', taken to correct malfunctioning of the engine, 'Fuel System', or emissions control system(s) during an emissions test, including 'Stabilisation Distance' accumulation (refer Appendix 7 of ADR 37/...).

   CORRECTLY FITTED- the design configuration of the 'Seatbelt Assembly' as installed in the vehicle using the 'Anchorages' and 'Sash Guide' devices, and adjusted around the occupant of the seating position to eliminate slack, with the occupant seated such that his centreline lies in the 'Seating Reference Plane' of the seating position.

   COUPLING - a mechanical assembly which provides connection between a drawing vehicle and a trailer.

   COUPLING HEAD - the brake line couplings to which a trailer's 'Brake System' would normally be attached. For the purpose of testing the 'Coupling Head' must be positioned as near as practical to the position in which it is most likely to be mounted -in service. Vehicles intended to tow 'Semi-trailers' must be equipped with flexible pipes for making the connection to 'Semi-trailers'. The coupling heads will therefore be at the extremity of those flexible pipes.

   CRANE - a machine for raising and lowering heavy weights.

   CRITICAL AREA A - In the case of LEP, MA and MC vehicles, it is the area of the windscreen bounded by a plane tangential to the bottom of the '95th Percentile Eye Ellipses' which includes a line at ground level transverse to the longitudinal axis of the vehicle 11 m forward of the rearmost '95th Percentile Eye Ellipses' point, and 2 diverging vertical
