The traffic signal is an important invention that plays a critical role in managing traffic flow and preventing accidents on the road. While the modern traffic signal was invented by Garrett Morgan, a Black inventor and entrepreneur, in the early 20th century.

Garrett Morgan was born in Kentucky in 1877 and moved to Cleveland, Ohio, where he started his own sewing machine repair business. Morgan's interest in solving problems and improving safety led him to develop various inventions, including the traffic signal.

In 1923, Garrett Morgan patented his three-position traffic signal, which featured a manual design with a moving arm that indicated when drivers should stop and go. This invention was a major advancement in traffic management and safety, as it helped reduce accidents and regulate the flow of vehicles on the road.

Morgan's traffic signal invention was eventually adopted by cities across the United States and around the world, transforming the way traffic was controlled and improving road safety for drivers and pedestrians alike. Garrett Morgan's legacy as a Black inventor and entrepreneur continues to be celebrated today for his contributions to transportation and public safety.
