Dierks Bentley is climbing up the Billboard Country Singles chart with 5-1-5-0. If you've been singing along with the song and wondering what you're singing about, we've got the answer.

Bentley recently revealed to Taste of Country the meaning behind 5-1-5-0, “I had written this song on the beach one day and I said, ‘Let’s get 5150.'" Rock fans know it as a Van Halen album and song from 1986, but the 'Free and Easy' singer explains that it’s also the police code for a criminally insane person.

The song is featured on Dierks Bentley's album 'Home.'
