Apparently road signs are nothing to be paid attention to in Sydney, Australia. So much so that for semi-trucks down under, the city had to create giant stop signs that appear in a water feature in the middle of the road.
Jalopnik posted a story last week on the water-curtain stop signs, along with a video clip (see it below) of the news coverage of the reasoning behind the stop signs, which came about after too many truck drivers crashed into tunnels that weren’t tall enough for the trucks to fit into.
The systems basically work by dropping a curtain of water which is then used as a backdrop for a gigantic stop sign projection when a vehicle too tall to enter is detected by a sensor. The news report shows one truck in particular ignoring warning low-overhead sign warnings far enough out to change course. They’re ignored, however, and the last-resort water-curtain sign is triggered, which then gets his attention.
