Length—trailers
4 Length—trailers
This section applies to a trailer that is, or forms part of, a heavy vehicle.
On a semitrailer, dog trailer or tag trailer—
the distance from the front articulation point to the rear overhang line must not be more than 9.5m; and
the distance from the front articulation point to the rear of the trailer must not be more than 12.3m.
The part of a semitrailer or tag trailer, or anything attached to a semitrailer or tag trailer, in front of the trailer’s front articulation point, other than another vehicle, must not protrude beyond the prescribed limit.
For the purposes of subsection (3), prescribed limit is an imaginary line created by drawing a semicircle of 1.9m radius from the centre of, and forward of, the front articulation point.
Example—
Measuring distances for subsections (1) to (4)
A semitrailer with more than 1 front articulation point must comply with subsections (2) and (3) when measured at one of the points.
A trailer built to carry cattle, horses, pigs or sheep on 2 or more partly or completely overlapping decks must not have more than 12.5m of its length available to carry cattle, horses, pigs or sheep.
In a B-double built to carry cattle, horses, pigs or sheep, the 2 semitrailers must not have more than 18.8m of their combined length available to carry cattle, horses, pigs or sheep.
For subsections (6) and (7), the length available for the carriage of cattle, horses, pigs or sheep on a trailer is measured from the inside of the front wall or door of the trailer to the inside of the rear wall or door of the trailer, with any intervening partitions disregarded.
Despite subsection (2)(b), the distance from the front articulation point to the rear of a semitrailer may be up to 13.6m if the trailer—
is designed and constructed for the positive control of temperature through the use of refrigerated equipment; and
has a distance from the front articulation point to the rear overhang line of not more than 9.9m; and
does not operate in a B-double or road train combination; and
otherwise complies dimensionally.
Example—
Despite subsection (2)(b), the distance from the front articulation point to the rear of the semitrailer may be up to 13.2m if the trailer—
has a distance from the front articulation point to the rear overhang line of not more than 9.5m; and
does not operate in a B-double or road train combination; and
otherwise complies dimensionally.
