NJ Overhead Highway Warnings

They really know how to motivate motorists in New Jersey! Cruising along the mountainous area of I-95 South that leads away from the George Washington Bridge, the first overhead warning sign I came to in the Garden State read:

SLOW DOWN:

SAVE GAS!

I think this is truly grand. It's so refreshingly direct. In New York, I would have expeced to see more of the usual overhead sign boilerplate, after a "Slow Down" command, such as, "It Saves Lives," or "It's the law." I say it makes more sense to appeal to our pocketbooks, rather than our minds.
