Cheyenne, WY (September 1, 2025) – A multi-vehicle collision involving a semi-truck and two passenger vehicles resulted in reported injuries on Sunday evening along South Greeley Highway near West Wallach Road. The incident occurred shortly before 8:00 p.m. and prompted a coordinated emergency response from Cheyenne Police, Laramie County Sheriff’s Office, and local fire and EMS units.
According to dispatch communications, the crash may have involved a T-bone impact and occurred slightly south of the reported intersection. Emergency teams arrived to find at least one vehicle with significant damage and several individuals in need of medical assessment. Fire crews evaluated victims for a range of injuries at the scene, and EMS resources were stretched thin at the time of response, potentially delaying ambulance transport.
While the total number of injured parties has not been confirmed, injuries were acknowledged over emergency radio traffic. First responders worked to stabilize the area and initiate an investigation into the events leading to the crash. Traffic was slowed in both directions while cleanup and documentation efforts continued.
The identities of those involved have not yet been released, and the incident remains under active investigation by local authorities.
We send our thoughts to everyone affected by this crash and hope for a full recovery for those injured.
Semi-Truck Crashes in Wyoming
Injuries stemming from collisions involving semi-trucks are often more severe due to the force and size disparity between commercial and passenger vehicles. South Greeley Hwy, a key thoroughfare in Cheyenne, frequently handles both local and freight traffic, creating added risks at intersections such as West Wallach Road, where turning and merging are common.
Crashes like Sunday’s highlight the heightened dangers of evening traffic in mixed-use corridors. A reported T-bone collision with a semi-truck can lead to side-impact trauma, which is especially hazardous for occupants of smaller vehicles. Quick decisions and limited visibility during dusk hours only compound the risk.
First responders often face additional challenges when EMS resources are low, as was the case during this incident. Still, swift coordination between fire, police, and dispatch helped secure the scene and initiate care.
