Several counties in the U.S. are known to have no traffic lights, primarily due to their rural nature and low population density. Notable examples include Kalawao County in Hawaii, which is located on the island of Molokai, and several counties in Wyoming, such as Niobrara County. These areas often rely on stop signs and other traffic control measures instead of traffic lights. Overall, counties without traffic lights tend to be less urbanized and have fewer major roadways.
Logically, unless there were reasons to control traffic, there would have been no reason to create or install traffic lights. Because "traffic" generally comprises vehicles (motorized or otherwise), the traffic was probably there prior to the lights. Certainly, there were mechanical traffic signals that preceded traffic lights, not to mention traffic officers who once stood at busy intersections to direct traffic on a regular basis.
