Solution on the road: traffic lights that will surprise you

Almost everyone knows what a regular traffic light looks like. No wonder its image was chosen for the international CAPTCHA test, designed to determine who's trying to log in, a person or a computer bot. Children are taught to understand this device's signals from an early age because the slightest mistake on the roadway can cost a person their health and life. You can find a traffic light not only on busy city streets; it's also used on railways, ship canals, and shipping.

But have you ever wondered why traffic lights look like this? Who invented the first traffic control system and when? Is it really so simple in the world of traffic lights: "one-two-three," or do they still have something to surprise us with? Well, if so, you're on the right track. Today, on International Traffic Light Day, RUBRYKA decided to introduce you to unusual traffic lights around the world, which not only surprise but also demonstrate the evolutionary process of this device necessary for human safety.
