Hacking programmable road signs

Fri, Jan 23rd, 2009

This road sign has been hacked to read 'Zombies Ahead.' According to i-hacked.com, it is fairly easy to break into the programmable digital signs' electronics and re-program the text on them.(Credit: i-hacked.com)

We see them everywhere these days, digital signs by the side of the road telling us about road conditions or that we should prepare to stop or that our local bridge might be closed next Tuesday from noon to midnight. And if you're like me, you've always just assumed that the message on the signs is legitimate and properly authorized.

But what if the sign, instead of reading something like "Ice Ahead," instead was flashing the message, "Zombies Ahead."

It's true that in San Francisco or a few other cities, such a sign could be put up by local transportation officials to warn people of an impending zombie march, but even in those places, the more likely explanation would be that the sign was hacked.
