Sherman County, OR (May 4, 2026) — Two people were injured Monday afternoon after a semi-truck was reportedly driven the wrong way on Interstate 84 near Biggs Junction, according to Oregon State Police. Troopers responded around 4:04 p.m. to reports of a commercial truck traveling westbound in the eastbound lanes of I-84.
Investigators said the semi-truck allegedly entered the eastbound lanes from U.S. Highway 97 and continued against traffic. During the incident, the driver of a Toyota 4Runner reportedly took evasive action to avoid the oncoming truck, causing the SUV to roll over and come to rest in the slow lane near milepost 103. The driver and a passenger in the Toyota were transported to a hospital with injuries.
Authorities stated that the semi-truck continued driving after the crash before later turning around and reentering the proper lanes. The truck was eventually located by law enforcement near milepost 85. Police said the truck driver now faces multiple charges, including reckless driving, reckless endangering, felony hit-and-run, and assault-related allegations. The investigation remains ongoing.
Even when a commercial truck does not directly collide with another vehicle, driving the wrong way on an interstate can create an immediate emergency for surrounding drivers. In this case, investigators believe the rollover happened when another driver attempted to avoid the oncoming semi.
Crashes caused by evasive maneuvers can still lead back to the actions that created the danger in the first place. Investigators will likely examine how long the truck was traveling against traffic, what opportunities existed to correct course, and how much time other drivers had to react.
One of the key issues here will be understanding how the semi-truck entered the wrong side of the interstate and continued traveling in that direction. Investigators may look at roadway signage, the truck’s route, and whether the driver showed signs of confusion, impairment, fatigue, or a medical issue.
Because the truck reportedly continued driving after the rollover occurred, investigators may also examine whether the driver was aware of the danger being created at the time. Commercial truck drivers are expected to maintain awareness of roadway conditions and operate with a high degree of caution due to the size and risk associated with these vehicles.
Crashes like this are often more complicated than standard collisions because the injured vehicle may not have been struck directly. Instead, investigators must determine whether the rollover was a foreseeable result of trying to avoid the wrong-way truck.
That can involve reviewing vehicle positions, witness accounts, and timing to understand whether the Toyota driver had any safe alternatives once the semi appeared in the wrong lanes.
With multiple charges pending and several moving parts to the incident, investigators will likely spend significant time reconstructing the sequence of events. That includes determining how the truck entered the interstate, how far it traveled against traffic, and what happened in the moments before the rollover.
