Australian road trains have horizontal signs front and back with {{convert|180|mm|in|sigfig=2|abbr=on}} high black uppercase letters on a reflective yellow background reading "ROAD TRAIN". The sign(s) must have a black border and be at least {{convert|1.02|m|ft|sigfig=2|abbr=on}} long and {{convert|220|mm|in|sigfig=2|abbr=on}} high and be placed between {{convert|500|mm|in|1|abbr=on}} and {{convert|1.8|m|ft|sigfig=2|abbr=on}} above the ground on the fore or rearmost surface of the unit.

In the case of B-triples in Western Australia, they are signed front and rear with "ROAD TRAIN" until they cross the WA/SA border where they are then signed with "LONG VEHICLE" in the front and rear.

Converter dollies must have a sign affixed horizontally to the rearmost point, complying to the same conditions, reading "LONG VEHICLE". This is required for when a dolly is towed behind a trailer.
