Water stop sign: Virtual barrier made from curtain of water halts lorries from driving through too small tunnels | Mail Online

What a brilliant idea.

That's very clever, I really like it.

Just add car shampoo to get a free carwash at the same time

Might not be so useful in daylight.....

Agreed, it wont be as visible. But,the light intensity difference between out and inside of tunnel should be enough to make up for it.

In this country just project "STOP" onto the rain

Great idea but I suppose also the success of it might depend on how fast the lorry was travelling whether it could stop in time...

I'd just see water and stop!

I wouldn't need to be told.

Clever idea

I wonder what the holdup is like when he tries to reverse an artic back down the road and whether it's less than if he hit the tunnel
