Sign 1, immediately after intersection: “For air quality and traffic control purposes, lights along Greenback Lane are set for 40 mph”
Sign 2, 250 feet farther down the same road: “Speed Limit 25*”
…
Happy Monday to you, too.
(*This is actually a school zone, and the speed limit does increase to 40 after the school, but it’s always amused me that someone decided to place the first sign before, rather than after, the slow zone.)
