Non-detection at traffic lights in the United States
Traffic lights that do not service traffic due to non-detection may not meet the federal legal definition adopted by most states for a traffic control signal, which is any device “by which traffic is alternately directed to stop and permitted to proceed”.
Did not know this was a thing. The abomination of a stoplight that leads to my street does this sometimes. I’m running the fucker the next time it misses my little car.
