The Hidden Power of Zebra Stripes

Zebra crossings were designed to be seen by drivers in the dark, not just to guide pedestrians. Their high-contrast white stripes were chosen specifically because they reflect moonlight and headlights brilliantly against dark roads.

Before these crossings became standard, road safety experts struggled to make pedestrians visible at night. Engineers discovered that the alternating pattern created a strobe-like flicker effect that alerts drivers to focus on the road ahead. Today, this simple paint job remains one of the most effective life-saving technologies ever deployed on city streets. It is a brilliant example of using simple visual psychology to force people to pay attention.
