Caution, Stittsville motorists: there may be zombies ahead. Or at least, a very specific zombie body part.

A traffic sign on Hazeldean Road was hacked recently to warn drivers against the supposed presence of zombie genitals.

Pictures and video of the hacked sign started appearing on the social media websites Instagram and Twitter Monday morning. It's unclear, however, when the sign was hacked.

The hacked sign sits on Hazeldean near West Ridge Drive in Ottawa's Stittsville neighbourhood.

The sign is owned and operated by Ontario's Ministry of Transportation.
