Normally, these signs flash messages like "New traffic pattern ahead," "Road closed" or "Road work ahead." The sign in Houston, located near the intersection of Waugh Drive and Allen Parkway, flashed messages like "Warning: Hurricane Human," "Triassic weather ahead," and "Global warming at work," the television station reported.

Other messages included "Goodbye Arctic Ice," and "We are the asteroid," KTRK reported.
Houston officials have not commented about the sign, the television station reported.
It's not the first time a Houston traffic sign has been hacked.
In May 2017, protesters hacked into a digital sign and put up a message to impeach President Donald Trump, the Houston Chronicle reported.
