Steel Rail at Center of Road Prevents Head-On Crash
White center lines on the highway warn motorists to stay in their own lanes, but they don’t prevent a crash if someone ventures across the line at the wrong time. Real protection is now offered by a center-line guard rail of convex steel strips supported by spring-steel posts, sturdy and resilient enough to absorb the shock of impact and deflect the car back to its proper lane. This traffic divider occupies no more space than is taken by the double white line.
