so, I had a discussion with a work colleague regarding roads in our wonderful country posted as unlimited speed (black circle with a black line through the middle on a 45 deg angle) and he claims that these roads are max limited to 110km/hr in Western Australia?
I don't believe this to be correct, as I am quite confident that I know that in NT, these roads are definitely unlimited speed provided you drive to the conditions (i.e., police could prosecute if I drove at a ridiculous speed not suited to the local conditions at the time)

however, I a struggling to find any reliable evidence to support either case as the rule applies to particularly WA? I would like to find reference to a gov source to support his stance or my thoughts?

Your mate is right, WA applied a blanket speed limit of 110km/hr many moons ago.
They still haven't got around to replacing all the unlimited signs yet. You won't see very many of them, and the ones you do see are very old.

the bottom of the page says,

the default speed limit for open areas is 110 km/h. This applies on roads outside built-up areas.
the derestricted speed zone limit is 110 km/h and this applies only to areas as signposted outside the metropolitan area.

I always took those signs to mean "no restrictions" rather than no speed limit.

i was under the impression NT was the only territory with rds that have no speed limit. But maybe that too could be a falsehood created by some one misinterpreting the signs? We definitely have them up north in WA.

en.wikipedia.org/wiki/Speed_limits_in_Australia

The sign actually means State Limit.
SA has a State Limit of 110 km/h.
NT doesn't have a State Limit, and I think it is the only one that doesn't, so in WA it would mean 100 or 110, not unlimited.

NT now has a state limit of 130kms and i'd imagine it would have been a lot of fun driving at 250+.... legally ??

These days drop 3rd or do 20kms over and you're pretty much a top level criminal!

In WA it means state limit but you won't get advisory signs like a 80kph recommendation on a corner. In effect it means 110 but we won't give you any tips about corners etc.


Still a lot of them around out bush

I lived in the NT during the open speed period and I'll point out the problem with open speed limits is your fuel consumption. See how far you get sitting on a silly speed. Then see how much the only fuel stop for 200ks in any direction charges and watch as that stupid guy sitting on 100k you overtook drives past you not stopping.

Ha ha don't come to the Police State Of Victoria then. You'll get booked if you're doing 3-4km/h over. Criminal.

Fuel consumption! Who cares about that stuff we'll just dig more up!

The maximum speed is 120 Kmh through Australia and may be federal law, only because many years back after the roads by around 1990 had been remade into concrete highways they had some immense smashes of which speed was always to blame and they actually lowered the maximum country-wide to 100Kmh. That was too crippling economically on the transport industry and people begun to get killed by fatigue on long journeys (self defeating) so they brought it back up to 120 Kmh.

^^ No no lets all theorise and talk about 120kph, goes as fast as you want and stuff.

Plenty of multi lane roads in Australia have a cement/concrete surface, BUT, mainly cement is under the bitumen surface !
Waste of time to drive a car in this country because it is not (for most or all) legal to go faster than 120Kmh but more than that to do it the concentration and work "overhead" at driving a road vehicle is immense.
This is following type of activity is that should be occurring (for any long distance or "to out of town" travel) and is now around average wage earner level since 2013.

Thanks! That cleared it up.

Slower speeds and still colliding with each other, 80km soon

Two men injured in head-on crash on Indian Ocean Drive

Staff reporter, PerthNow November 29, 2017 11:57AM

Two men have been injured on a notorious stretch of road north of Perth.

Two cars hit each other head-on on Indian Ocean Drive about 9km south of Cervantes at 10.15am.

The men were taken by ambulance to Joondalup Health Campus and the extent of their injuries is unknown.

The crash comes less than a month after the State Government slashed the speed limit on Indian Ocean Drive after a series of crashes which have seen ten people die in the last 18 months alone.

^^^ and that is the new good bit.

Maybe its not the speed limit or the road!!!!

A road is only dangerous the first time you use it,,

After that baaing semi naked sheep (for the kiwis) falling space stations and kangaroos armed with M50's, it is always the driver.

You (not aimed at any individuals) don't need to speed or sit on the speed limit, you don't have to overtake that slow moving caravan. You can never stop a Kiwi staring at naked sheeps.
