Laservision stop signs in Sydney road tunnels

(1/3) > >>

Halcyon:
These kinds of systems have apparently been installed on Sydney roads for almost a decade, yet I only learned of them today.

They are a "last ditch" effort in an attempt to stop over-height vehicles entering tunnels. You would think the plethora of warning signs, lights and flashing message boards would be enough, but apparently not for some drivers.

Such a simple yet clever system.



SeanB:
Bet there are still some who drive through that.

Berni:
Oh nice one. Such a simple yet so effective solution. Mostly since it suddenly appears right in front of you, if you don't notice that then you might as well be sleeping at the wheel.

The neat thing about it is that it can't damage anything since its just water. Deploying any sort of normal physical sign into the road like that would otherwise have serious safety concerns if someone hits it. In dense traffic id imagine a few cars get showered by it in order to display the stop sign soon enough to give the truck a safe braking distance.

Opposite of the solution of the other internet famous bridge:

They did add regular signs, but you can see the big metal pillars with cross bracing under it, so it makes sure the bridge can survive the sideways loads of anything the idiot divers throw at it. But this is not nearly as busy of a road, so i suppose an half hour to pull the truck out of there is not that bad.

I bet people still ignore it, "didn't think it meant me"

That can opener bridge was exactly the one that sprang to minds too, so many drivers are idiots

I liked the irony of the phrase on the back door:
