McCammon, ID (February 20, 2026) – Idaho State Police are investigating a three-vehicle crash that occurred early Thursday morning on Interstate 15 just north of McCammon. The collision happened at approximately 5:20 a.m., resulting in significant roadway blockage after multiple vehicles overturned.
According to authorities, a Toyota pickup truck pulling a flat-bed trailer loaded with vehicles was traveling southbound on I-15. The truck was driven by a man from Guatemala. Investigators say the rear of the trailer was struck by a Honda Accord operated by a man from Pocatello.
Following the initial impact, both the Toyota pickup and the attached trailer rolled over and came to rest across both southbound lanes of travel. The crash created a dangerous situation for approaching motorists during the early morning hours.
After the pickup and trailer overturned, a Toyota 4-Runner driven by a woman from Inkom collided with the disabled pickup. Emergency responders arrived promptly to secure the scene and assess those involved. Fortunately, no injuries were reported in connection with the crash.
Traffic in the southbound lanes was affected while crews worked to clear the roadway and remove the overturned vehicles. Idaho State Police continue to investigate the circumstances surrounding the collision.
Why Multi-Vehicle Crashes on Interstates Can Become So Dangerous
Multi-vehicle crashes on major highways like Interstate 15 can quickly escalate due to high speeds and limited reaction time. In this incident near McCammon, the crash occurred around 5:20 a.m., a time when visibility may be reduced and drivers are adjusting to early morning traffic conditions.
When a vehicle towing a flat-bed trailer loaded with cars is struck from behind, the sudden shift in weight can cause instability. Trailers are particularly vulnerable to swaying or rolling when impacted, especially at highway speeds. The fact that both the Toyota pickup and its trailer rolled and came to rest blocking both southbound lanes illustrates how rapidly a single collision can shut down an entire stretch of interstate.
Secondary impacts are another major concern. After the initial crash left the pickup and trailer overturned in the roadway, the Toyota 4-Runner driven by a woman from Inkom struck the disabled vehicle. When large obstacles suddenly block travel lanes, approaching drivers may have only seconds to react, increasing the likelihood of additional collisions.
Even when no injuries are reported, multi-vehicle crashes often result in significant property damage and traffic disruption. Interstate corridors like I-15 are vital transportation routes for commuters and commercial traffic. When both southbound lanes are blocked, delays can extend for miles and create further safety risks.
Drivers can reduce the likelihood of chain-reaction crashes by maintaining a safe following distance, remaining attentive to traffic patterns ahead, and adjusting speed during low-light conditions. Early morning travel requires heightened awareness, particularly on rural stretches of highway.
