He was making music while driving a semi near Kennewick. That’s not the worst part

Washington State Patrol troopers have seen a lot of strange things over the years.

But a traffic stop near Kennewick had a veteran trooper shaking his head and commenting on Twitter.

“Just when you thought you have heard it all ...,” tweeted Trooper Chris Thorson.

He said his co-worker, Trooper Aaron Trombley stopped a semi truck going 17 miles an hour over the speed limit and discovered the trucker had a side business.

The driver was producing and recording music while traveling down the highway, including a drop-down microphone hanging from the ceiling of his cab.

Thorson’s comment: #notacceptable

The driver was arrested on suspicion of driving under the influence of drugs.
