A wrong-way semi slammed head-on into a Toyota sedan on U.S. 287 in Larimer County early Saturday, killing a passenger and leaving the car's driver with serious injuries, according to state troopers.
The crash was reported around 4:47 a.m. near mile marker 355, between County Road 54G and Highway 14. The impact shut down that stretch of U.S. 287 while first responders treated the injured, documented the scene, and worked to clear mangled vehicles from the roadway.
Troopers Describe Wrong-Way Impact
According to the Colorado State Patrol, cited by Denver7, a 25-year-old man behind the wheel of the semi was traveling the wrong direction on U.S. 287 when he collided with the Toyota.
Investigators said a passenger in the sedan was pronounced dead at the scene. The driver of the Toyota sustained serious injuries. Troopers have not yet released the names of those involved or the total number of people in the sedan. No other injuries were reported.
As emergency crews focused on medical response, documenting evidence, and removing debris, the highway closure stretched on, affecting early-morning traffic in and out of the area north of Fort Collins.
Why Wrong-Way Crashes Turn So Deadly
Head-on collisions, especially when a large truck is involved, are far more likely to result in fatalities than many other types of crashes. Research published in the Journal of Safety Research finds that wrong-way crashes are responsible for several hundred deaths nationwide each year and carry higher fatality rates than more typical collisions.
Investigation Ongoing, Highway Reopens After Long Closure
CSP's Vehicular Crimes Unit is leading the investigation and, as of now, has not released any findings about what may have caused the semi to be traveling the wrong way. Troopers also have not shared any information about possible impairment.
The crash forced U.S. 287 to remain closed in the area while crews handled crash response and vehicle recovery, creating significant detours for drivers heading north of Fort Collins. As Denver7 reported, authorities urged motorists to steer clear of the stretch until the roadway could safely reopen.
What Drivers Need To Know Now
Travelers who use U.S. 287 should be prepared for residual delays and possible lane restrictions in the area as cleanup and investigation wrap up. Drivers are encouraged to check COtrip for current road conditions, closure details, and detour routes before heading out.
Anyone who witnessed the crash or may have information helpful to investigators is asked to contact the Colorado State Patrol Public Affairs office. Contact details are listed on the Colorado State Patrol website.
