In the Brightest Day and the Blackest Night, No One Shall Hurt Ohio Snowplows
It was either the above or reciting the Mr. Plow episode from The Simpsons. The Ohio Department of Transportation has said Green Lantern comic books were the inspiration for the new green lights being installed on snowplows.
In an attempt to lower crashes with plows the traditional yellow lights are being replaced with the more easily visible green lights. From the ODOT news release:
Taking a cue from the comic book superhero who uses green light to protect the people of Earth, the Ohio Department of Transportation is hoping a Green Lantern will protect its snowplows from a dangerous spike in crashes this season.
