B‑doubles
 (1) A fifth wheel coupling used in a B‑double must have a D‑value complying with Australian Standard AS 1773 – 1990, Articulated Vehicles—Fifth Wheel Assemblies.
 (2) A turntable used in a B‑double must have a D‑value complying with Australian Standard AS 1773 – 1990, Articulated Vehicles—Fifth Wheel Assemblies.
 (3) A fifth wheel coupling used in a B‑double that is built for a 50 millimetre or 90 millimetre kingpin must:
 (a) be built to meet the dimensional requirements in Australian Standard AS 1773 – 1990, Articulated Vehicles—Fifth Wheel Assemblies; and
 (b) not be worn away more than is recommended by that Australian Standard.
 (4) A fifth wheel coupling used in a B‑double that is built for a 75 millimetre kingpin must:
 (a) be compatible with the kingpin described in subclause 9.10(4); and
 (b) not be worn away more than is specified in clause 9.7.

9.6  Selection of fifth wheel couplings for road trains
 (1) A fifth wheel coupling used in a road train must have a D‑value complying with Australian Standard AS 1773 – 1990, Articulated Vehicles—Fifth Wheel Assemblies.
 (2) A turntable used in a road train must have a D‑value complying with Australian Standard AS 1773 – 1990, Articulated Vehicles—Fifth Wheel Assemblies.
 (3) A fifth wheel coupling used in a road train that is built for a 50 millimetre or 90 millimetre kingpin must meet the dimensional requirements in Australian Standard AS 1773 – 1990, Articulated Vehicles—Fifth Wheel Assemblies.
 (4) A fifth wheel coupling used in a road train that is built for a 75 millimetre kingpin must be compatible with the kingpin described in subclause 9.10(4).

9.7  Deciding the D‑value of fifth wheel couplings
  In testing a fifth wheel coupling built for a 75 millimetre kingpin used in a B‑double or road train to decide whether its D‑value meets the requirements of subclause 9.6(1), the longitudinal movement (after readjusting the jaws of the coupling using a kingpin built to the dimensions mentioned in subclause 9.10(4)) must not be more than 4 millimetres.

9.8  Mounting of fifth wheel couplings on B‑doubles and road trains
  A fifth wheel coupling must be mounted on a prime mover or a semi‑trailer used in a B‑double or a road train in accordance with the requirements of Australian Standard AS 1771 – 1987, Installation of Fifth Wheel and Turntable Assemblies.

9.9  Branding of fifth wheel couplings on B‑doubles and road trains
  A fifth wheel coupling on a vehicle manufactured on or after 1 July 1991 forming part of a B‑double or road train must be clearly and permanently marked in accordance with Australian Standard AS 1773 – 1990, Articulated Vehicles—Fifth Wheel Assemblies with:
 (a) the name or trademark of its manufacturer; and
 (b) its
