A two-vehicle crash on Weld County Road 100 killed one person and transported another for medical treatment Saturday afternoon, closing a stretch of the rural roadway between county roads 13 and 17 as troopers worked the scene. The Colorado State Patrol confirmed the collision happened around 12:29 p.m., with one of the two vehicles involved having a confirmed death.
According to FOX31 Denver, at least one person was killed in the crash, while another occupant was transported for medical treatment. The outlet reported that Colorado State Patrol troopers were actively investigating the scene, and Weld County Road 100 remained closed between County Roads 13 and 17 as work continued. The stretch is in Weld County and intersects U.S. Highway 85 at Nunn, roughly 25 miles north of Greeley and 15 miles east of Wellington, according to Soaring V Fuels.
A County Already Leading the State in Road Deaths
The crash lands in a county that has become a grim statistical outlier on Colorado's roads. Preliminary state data shows Weld County recorded 76 traffic fatalities in 2025, tying Denver County for the highest total of any county in the state and marking a 13% jump over Weld's 2024 figures, per the Colorado State Patrol. Statewide, traffic deaths reached 701 in 2025, a 2% rise from 689 the year before, reversing two years of declining fatalities after a sharp surge in November and December, according to the Colorado Department of Transportation.
Weld County also ranked among the state's top four counties for impaired-driving traffic fatalities in 2025, alongside El Paso, Denver and Adams counties, the Colorado Department of Transportation reported in February. Impaired and distracted driving are also part of the article's discussion.
What Colorado Law Says About Fatal Careless Driving
No cause has been determined for Saturday's crash, and the Colorado State Patrol's investigation remains active. If investigators eventually determine a driver operated a vehicle carelessly and without due regard for road conditions, and that this proximately caused a death, Colorado law treats that as a Class 1 misdemeanor traffic offense under Colorado Revised Statutes § 42-4-1402, punishable by up to one year in jail and fines up to $1,000, according to Justia Law. Colorado also implemented a statewide hands-free driving law in 2025, barring drivers from holding cellphones or other electronic devices while behind the wheel, per Jordan Law.
The closure of WCR 100 accompanied the fatal-crash investigation. Traffic-related incidents remain one of the leading causes of line-of-duty deaths for law enforcement personnel in Colorado. The Colorado State Patrol has also issued roadside-safety messages.
County Has Been Investing in Nearby Rural Roads
Weld County Public Works has spent recent years on multi-year reconstruction projects across the rural road network near WCR 100, the county government has said. The identities of those involved in Saturday's crash, and the precise cause, had not been released as of Saturday afternoon.
The crash adds to the broader road-safety discussion in Weld County.
