The Cheyenne Police Department is warning drivers to watch their speed to avoid being "Grinched" this holiday season.

As part of an effort to reduce crashes, the Grinch and his trusty dog Max will be monitoring high-traffic areas in Cheyenne this Wednesday and helping cops write tickets to speeders.

"People need to remember to watch their speed, wear their seat belt and don't use that phone while you're driving or the Grinch will radio ahead to a police officer who will pull you over," said Chief Brian Kozak.

This is the fourth year the Cheyenne Police Department has enlisted the Grinch's help.

"People are in good spirits about it and it really gets people talking," said Kozak. "It's kind of a fun way to promote traffic safety."
