After his judgmental toot, the trooper pulled Brian Miner over and threatened to give him a ticket for unlawful use of a horn.
Miner taped the entire encounter and posted the clip on YouTube.
The officer is aggressive at first, but he changes his tune after Miner informs him that their exchange is being recorded.
The trooper eventually apologizes to Miner and declines to give him a ticket.
"And that's what happens when they know you're recording," Miner says near the end of the clip.
