Hackers change public safety message you gotta check out the video on the web page,they put more than that on them.. http://www.kxan.com/dpp/news/Road_signs_warn_of_zombies
I saw that... it was on a web page telling how to do it.. haha as long as they didn't take away a sign that said "bridge out ahead"
Hahaha, somebody posted a link to a tutorial on how to hack those same signs just the other day! And I love how they make it sound like super geniuses hacked it, "figuring out the password" as they did. It's a simple command to reset the password to its default which is always the same.
edu for hacking = walk up to it, type in 1234, then type your message? I mean, hacking the sign is hilarious...but it would have been funnier to put something like "Caution: Terrorists Sightings in Area..Lock doors, hide children"
