A significant crash in Meridian affected Interstate 84 traffic Tuesday afternoon and evening for four hours, according to a news release from Idaho State Police, with all eastbound lanes blocked near Meridian Road, which is Exit 44.
Traffic was diverted at Exit 42, on Ten Mile Road, but the eastbound lanes still were backed up all the way to the west side of Nampa.
Police said Wednesday that a 28-year-old man from Bonney Lake, Washington, was driving east in a Ford truck towing a 15-foot trailer full of gravel. The trailer “jackknifed” when the man hit his brakes, police said. A jackknife accident occurs when a “trailer moves out in front” of a truck to “form a 90-degree angle at the tow hitch, which serves as the point of connection for the two parts,” according to FVF Law.
A 56-year-old man from Pasco, Washington, driving a semitrailer collided with the Ford truck at about 2 p.m., according to police. This caused diesel to spill on the road, the Ada County Highway District said on social media, and all of the lanes were closed for cleanup of the accident and spill.
Idaho State Police said both drivers were wearing seat belts and did not report any injuries.
