In Australia, a [[truck driver]]'s license is required for any motor vehicle with a [[Gross Vehicle Mass]] (GVM) exceeding {{convert|4.5|t|abbr=on}}. The motor vehicles classes are further expanded as:
;Combination
* '''HC''': Heavy Combination, a typical prime mover plus semi-trailer combination.
* '''MC''': Multi Combination, e.g.,&nbsp;B&nbsp;Doubles/road trains

; Rigid
* '''LR''': Light rigid: a rigid vehicle with a GVM of more than {{convert|4.5|t|abbr=on}} but not more than {{convert|8|t|1|abbr=on}}. Any towed trailer must not weigh more than {{convert|9|t|1|abbr=on}} GVM.
* '''MR''': Medium rigid: a rigid vehicle with 2&nbsp;axles and a GVM of more than {{convert|8|t|1|abbr=on}}. Any towed trailer must not weigh more than {{convert|9|t|1|abbr=on}} GVM. Also includes vehicles in class ''LR''.
* '''HR''': Heavy Rigid: a rigid vehicle with three or more axles and a GVM of more than {{convert|8|t|1|abbr=on}}. Any towed trailer must not weigh more than {{convert|9|t|1|abbr=on}} GVM. Also includes articulated buses and vehicles in class&nbsp;''MR''.

;Heavy vehicle transmission
There is also a heavy vehicle transmission condition for a license class ''HC'', ''HR'', or ''MC'' test passed in a vehicle fitted with an automatic or synchromesh transmission; a driver's license will be restricted to vehicles of that class fitted with a synchromesh or automatic transmission. To have the condition removed, a person needs to pass a practical driving test in a vehicle with non-synchromesh transmission (constant mesh or crash box).<ref>{{cite web|title=South Australia License class information|url=http://www.sa.gov.au/topics/transport-travel-and-motoring|publisher=Gov't of South Australia|access-date=28 July 2016|archive-date=4 December 2016|archive-url=https://web.archive.org/web/20161204072222/http://www.sa.gov.au/topics/transport-travel-and-motoring|url-status=live}}</ref>
