Q & A: Whoa!

Stop sign and traffic light

Q & AQ: Which came first: traffic lights or stop signs?

A: Traffic lights came before stop signs. Here's a quick history:

  1. Traffic Lights: The first traffic light was installed in London, England, in 1868. It was manually operated and used gas for illumination. However, the modern electric traffic light was first installed in Cleveland, Ohio, in 1914.

  2. Stop Signs: The first stop signs were introduced in the United States in 1915, starting in Detroit, Michigan. These early signs were black letters on a white background, and the iconic red octagonal design wasn't adopted until 1954.

So, traffic lights predate stop signs by several decades!
