I don't think I'm hijacking this thread as the discussion has
well and truly drifted from the OPs question about WA to everyman's opinion and different state rules. Apologies if this upsets anyone.

"cut and paste from the peachey site “In NSW, if your vehicle and caravan weigh up to 4.5 tonnes combined, you can drive at the prevailing speed limit (that is, up to 110km/h), but if the rig weighs more than 4.5 tonnes in total, the speed limit is capped at 100km/h.”
All the discussion in this topic prompted me to look up the NSW legislation, as that is where I live.
It appears to me that the peachy site is not entirely correct. Here is the NSW LAW, taken straight from
the NSW Legislation:
"(2) However, if the number on the
speed limit sign is over 100 and the driver is driving a vehicle with a GVM over 4.5 tonnes or a vehicle and trailer combination with a GCM over 4.5 tonnes, the speed limit applying to the driver for the length of road is 100 kilometres per hour.
Note 1. Combination and trailer are defined in the Dictionary, vehicle is defined in rule 15, and GCM and GVM are defined in the Act."
The peachy website is wrong on two counts. Firstly it talks about what the vehicle/combination weighs. The rule is not dependent on what the vehicle actually weighs. It is dependent on the vehicle's MAXIMUM ALLOWABLE WEIGHTS. Ie, GVM and GCM. Secondly, it has misinterpreted the rule.
The first part of the NSW rule is easy. If you're driving a vehicle (without a trailer) not over 4.5 tonnes GVM you can drive at the posted limit. Over 4.5 tonne GVM you are limited to 100kph. Eg, a 5 tonne truck with no trailer, and loaded to 4.3 tonne, is still limited to 100kph by virtue of its 5 tonne GVM.
The second part "or a vehicle and trailer combination with a GCM over 4.5 tonnes, the speed limit applying to the driver for the length of road is 100 kilometres per hour" is the tricky but relevant part.
That clearly says that if your tug has a GCM over 4.5 tonne AND you're towing a trailer of ANY weight, you're limited to 100 kph. The peachy website's second error is in dismissing that.
Take a Ford
Ranger. GVM 3.2 tonne, GCM 6 tonne. Without a trailer, and having a GVM below 4.5 tonne, the speed limit in NSW is the posted limit - 110, 120 or whatever.
But add a trailer and the GCM provision cuts in. GCM of the
Ranger is over 4.5 tonne so the limit is 100kph.
An extreme example according to the rule would be a nearly empty
Ranger at say 2.4 tonne towing an empty box trailer that weighs, say 300kg. 2.7 tonnes all-up. But that doesn't count because the rule is based on the MAXIMUM possible combination mass, not the mass on the day.
Now, I'm not saying this is sensible or what we want, or want to believe, but it is the way the law is written.
A more realistic example would be the same
Ranger loaded to GVM at 3.2 tonnes towing a loaded 2.5 tonne ATM van, total 5.7 tonnes on the day - quite a realistic scenario. Same rule based on GCM applies, even though the combination is actually under the
Ranger's GCM. Again. the speed limit 100kph and, dare I say it, sensibly so. Capturing this sort of scenario is probably the intent of the rule.
The peachy website is not authoritative, it's just a private individual's travel blog. For that matter neither are the
NSW Road Users Handbook nor the
Towing page on the NSW RMS website authoritative . Both contain a disclaimer saying they are guides and refer readers to
the legislation for complete and accurate info.
In particular, the peachy site has taken quotes from the
RMS towing page out of context to support its erroneous conclusion.
