A second phase of changes to heavy vehicle trailer configurations were introduced on 1 July 2009 as part of the heavy vehicle charges reform approved by the Australian Transport Council.
Phase 1 - from 1 July 2008
Registered prime movers previously nominated for use under the medium combination prime mover (MP configuration) and the long combination prime mover (LP configuration) categories moved to the new multi combination prime mover (MU configuration) category.
Phase 2 - from 1 July 2009
Configuration of your heavy trailer is now based on one of five heavy trailer types (semi, lead, dolly, pig and dog trailers) and their axle grouping(s) (single, tandem, tri-axle and quad-axle).
New trailer configurations for heavy trailers will begin as follows:
- Pig trailers - TP
- Dog trailers - TD
- Semi trailers - TS
- Lead trailers - TL
- Dolly trailers - TY.
and will end with a number, or series of numbers representing the axle grouping(s) of your trailer.
Any heavy trailer that currently has a configuration (T1-T12) must have a new configuration assigned that incorporates heavy trailer type and axle grouping(s), so that the new fee charging structure can commence.
To have your new configuration assigned, complete and sign the information brochure (PDF795KB) and submit with your next registration renewal.
If you have multiple trailers you may complete and submit the configuration code advice form (PDF781KB) instead of the information brochure.
