Tulsa, Oklahoma is a relatively small city in the southern United States. With just over a million people in its great metropolitan area, Tulsa is much smaller than big cities like Dallas, San Francisco, New York or Chicago. Population isn't everything though, and when it comes to traffic signs, Tulsa is world class.

The city rarely gets any national attention, but when an Imgur user noticed the daily messages from someone who works for the city, Tulsa started to soak up the lime light.

Apparently whoever is in control of the signs above the interstate gets a little bored sometimes, but still wants to make sure drivers are being safe.

Tulsa has been known to have more traffic accidents than other cities its size, so maybe this new method of getting drivers' attention will work. One things for sure, we love it.

They even had some helpful advice for younger sons and daughters.

There's been no comment from the city of Tulsa, or the hilarious person who controls the signs, but with over 100,000 views it might only be a matter of time before someone takes credit.

This isn't the only time Tulsa had some attention because of their road signs, but last time the city wasn't laughing.

Way back in 2011, just in time for Halloween, someone hacked a road sign on the I-44 in Tulsa. Instead of warning commuters about upcoming construction, the sign warned drivers of a much....different situation.

The funny sign actually made national news, but the city didn't like the joke. Upset first that the signs could be hacked, they were also angry that commuters weren't receiving the information they needed to drive safely.

"For several hours drivers were not aware of upcoming road conditions," said Kenna Mitchell, who works for the city.

While they weren't laughing, millions of others were.

Another fun fact about Tulsa: the Yield sign was actually invented there. Police captain Clinton Riggs designed it and put it into place in the 1950s, now the signs are used all around the world.
