Union County, FL (February 28, 2026) – A 17-year-old boy died, and two other drivers were seriously injured, on Friday afternoon following a multi-vehicle crash in Union County.
According to the Florida Highway Patrol, the collision occurred at approximately 3:30 p.m. near State Road 121 and Southwest 79th Trail.
Investigators reported that a green Ford pickup truck was traveling southbound on State Road 121 behind a black Ford SUV. Authorities said the SUV slowed to make a left turn when the pickup truck failed to reduce speed and collided with the rear of the SUV.
The impact forced the SUV into the northbound lanes of traffic, where it was struck on the right side by a semi-truck traveling north. Troopers said the semi-truck subsequently overturned as a result of the crash.
The driver of the black SUV, identified as a 17-year-old from Lake Butler, was pronounced dead at the scene. Officials stated that he was wearing his seatbelt at the time of the collision.
Authorities said the green pickup came to a final rest on the east shoulder of the roadway, where it caught fire following the crash.
The drivers of both the pickup truck and the semi-truck sustained serious injuries and were listed in serious condition. No additional details regarding their identities or medical status have been released. The crash remains under active investigation.
We extend our sincere condolences to the family and loved ones of the young victim during this difficult time, and wish the injured parties a full recovery.
Rear-End Collisions at Highway Speeds Can Trigger Chain-Reaction Crashes
Rear-end collisions on rural highways frequently serve as the initiating event in multi-vehicle crashes. When a leading vehicle slows to make a lawful turn, following drivers must quickly perceive and respond to the change in speed. Failure to reduce speed in time can result in a high-impact rear collision.
On highways such as State Road 121, vehicles often travel at sustained speeds. At those velocities, stopping distances increase significantly, particularly for larger vehicles. When a rear-end impact propels a vehicle into opposing lanes, the risk of secondary collisions rises sharply.
Chain-reaction crashes involving commercial vehicles, such as semi-trucks, introduce additional hazards. Tractor-trailers require greater stopping distances and have higher centers of gravity, increasing the likelihood of rollovers during evasive maneuvers or side-impact collisions.
Crash reconstruction in incidents of this nature typically focuses on braking evidence, vehicle spacing, roadway markings, sightlines, and potential distraction factors. Investigators also assess whether traffic conditions, speed, or following distance contributed to the sequence of impacts.
Safety officials consistently emphasize the importance of maintaining adequate following distance, especially on rural highways where turning vehicles may slow unexpectedly and reaction times are critical.
