A truck driver is being held on bail after a road rage incident involving an armed motorist.

The incident happened Friday, April 22 at around 1:30 p.m. in Clark County, Washington, on Interstate 5 north of the Northeast 99th Street exit.

According to The Columbian, 33-year-old motorist Zachary Thurman was driving on I-5 when debris flew from a flatbed truck and struck his vehicle. Thurman tried to get the set driver’s attention, but was unsuccessful. Just then, 56-year-old trucker Joseph A. Horn began changing lanes in his own truck, forcing Thurman off the road and into the concrete wall. Thurman says Horn tried to trap him against the wall with his truck “like something you would see in a movie.”

Thurman says he was then able to escape and tried to pass the tractor-trailer in the right lane, but was hit and then spun, eventually stopping after hitting the grid of the truck. The truck then pushed the car aside before coming to a stop. Horn then exited his vehicle and approached Thurman with a wooden club, prompting Thurman to grab a pistol. Thurman then held the gun up to the car window to show Horn it was armed, but claims he did not point it at Horn.

Horn then returned to his truck as Thurman exited his vehicle from the passenger side to “get some distance”, and that’s when Horn exited his rig with his own gun. Thurman claims that Horn then threatened to kill him and chased him down the highway, forcing Thurman to sneak and squeeze through cars for cover as the gun was pointed at him. A witness then informed the two men that the police were coming and Horn walked away.

Horn later told investigators that he rammed into Thurman’s car because he believed he was intervening in a road rage incident between Thurman and the flatbed truck. Horn says he intentionally tried to sideline his platform in front of Thurman. Horn also admitted to grabbing a wooden club to hit the hood of Thurman’s car, and admitted to grabbing his gun and chasing Thurman in order to “disarm” him.

Officers were able to locate a revolver and a wooden baton in the center lane next to Horn’s tractor-trailer. Horn admitted the items were his. A black pistol and a knife were also found 100 feet behind Horn’s platform. These would have belonged to Thurman.

Horn appeared in court on Monday morning, April 25, on suspicion of first-degree assault. His bond has been set at $20,000 and he is scheduled for arraignment on May 6.
