Officials at the City of Regina aren't laughing about a road sign that was tampered with Sunday night.

Construction work on south Albert street was supposed to be marked by an electronic sign. However, someone changed the words on that sign encouraging drivers to "honk if you luv titties".

While the sign had some people chuckling online, Regina's Director of Roadways and Transportation Norman Kyle said the prank is no joke to the city.

"I wasn't very impressed," Kyle said. "[I] don't appreciate people tampering with our equipment. It's basically vandalism to public property."

Kyle said a password was needed to change the lettering on the sign, which means it may have been done by a city worker or former employee.

The passwords were changed on Monday, Kyle said, and tougher rules are in place to prevent similar tampering in the future.
