Officer Folczyk took the tie from Mr Keeney, and started to knot it around his own neck.
"While I do this," he said, "why don't you grab your proof of insurance and your driver's license real quick," Officer Folczyk said.
The police officer took a couple of goes at it, telling the motorist: "Probably not the best knot, but it will work."
Mr Keeney was sent on his way with a verbal warning - and later heard from the local police chief, who invited him to the police station for a lesson on how to tie ties himself.
"I went back and met with him for about 30 minutes and he taught me! It was cool," he told ABC News.
And to round things off, his presentation went fine, scoring Mr Keeney a mark of 92 out of 100.
