Police in Texas say 26-year-old Geoffrey Eltgroth changed the message on the construction zone sign to read ‘Drive Crazy Y’all’.

A witness saw Eltgroth changing the message and called police.

An officer found Eltgroth walking his dog near the scene and asked if he was behind the prank.

Police say Eltgroth admitted he did it because he thought it was funny. He said he was able to change the message by guessing the username and security code for the sign.

Eltgroth has been charged with criminal mischief.
