Ludwig,

The simple truth of the matter is that the truck would have to stop twice, so it's easier to just jump out and put the signs up together.

Yesterday I had to visit Tenterfield before going to Grafton so I drove south to Dundee and took the short cut via the Bald Nob road (Google Earth 29/34/41.15S x 151/52/11.45 N on the New England) to join the Gwydir H'way east of Glen Innes.
This is a popular road as it cuts about 30 kms off the trip compared to going back to Glen Innes to join the Gwydir.

The Bald Nob road is tarred all the way and there is no difficulty maintaining a speed of 100 kph however it is windy and with some tight blind curves; there is no centre line at all and only two signs in its entire length and they are 'T' intersection signs at each end where it joins the highways.

All in all a potentially very dangerous piece of road and apparently no one in authority cares a hoot.

Is Mise, I can’t come up with a better explanation!

Yep, it just seems to be fundamentally without any basis in law, common sense or road safety to have the signs together on each side of the road!

There are lots of backroads in the hilly parts of southwest WA, with 100kmh signs on them, on which even a hoon like Hasbeen would be battling to get up to 100!

And then there are absurd 50kmh stretches on wide flat straight main roads passing through small towns, with ridiculously long lead-in and lead-out zones!

The contrast is extreme!

Gee Ludwig, you can not be expected to know but in truth your last post truly honestly hurts, it does no joke hit right in the center of every road workers heart.
I would need a thousand posts to tell about the road workers factory floor and of the dead or injured road workers.
I have seen and heard of far too many.
I am proud to say I while being criticized for doing nothing [good morning Bruce, worked unpaid up to 17 hours on Sundays to get a safer workplace.
e mails and demanding letter, flowed until I hadto lock up my works office and go home
Picture a factory long and no walls in both ends, cars trucks speeding past your work bench at speeds some times oh yes sometimes near twice the speed limit.
I am proud of my award on the wall proud of the twin bridges I got named after a road worker killed on the job.
Ludwig every day, some time twice a *fool* demands to be told why sites just like you talk of, have no signs in place!
HIGH VISIBILITY,that is the reason for duplicate signs on both sides of the road.
A car over taking, *and it happens many times a day* the front one who is reducing speed, *Can Only See the sign on the other side of the road!
Drunk/drugged/old with poor eye sight a flagman and the workers he protects must step out in front of many every day and hope he gets home safe.
Too confront these stupid insults quote*why don,nt you blokes do this at night/day.
Why are you lot standing around as we drive past?
As opposed to running out in front of them?
In the end the thankless job of a road worker is one of being abused for fixing the road.
And too often by the same fools for not fixing it!

<< HIGH VISIBILITY,that is the reason for duplicate signs on both sides of the road. >>

Oh dear Belly, you are completely misunderstanding what I am saying.

Traffic indication is a massive job growth industry. It is only going to get bigger and worse especially when they make their actions legal.
At the moment anybody can place a traffic warming sign on the road and it becomes enforceable at law.
