A fake traffic stop turned into an unexpected proposal for one Utah woman this Valentine's Day.

Groom-to-be Alex enlisted the help of the Bountiful Police Department for a frightening - yet memorable - engagement.

Bride-to-be Cassie was driving with her boyfriend when they were pulled over by police. An officer ordered them out of their car.

As Cassie put her hands up, Alex got down on one knee. The fake traffic stop-turned-proposal was captured on video, and Bountiful police tweeted out photos of the moment Cassie said yes.

“I’m actually glad she said yes ‘cause I knew she was mad,” Alex said.
