St. Johns County, FL (January 5, 2026) – A serious vehicle collision involving a semi-truck led to a fire and left one person critically injured on January 4 along I-95 in St. Johns County. The crash occurred on the northbound side of the interstate near mile marker 307, according to officials from St. Johns County Fire Rescue.
Emergency crews responded to the scene and located a vehicle involved in a collision with a semi-truck. The semi caught fire following the crash, prompting an urgent response from both fire and hazmat teams. One individual was airlifted from the scene in critical condition to a nearby hospital for advanced trauma care.
In addition to the fire, the crash resulted in a diesel fuel leak, which required hazmat personnel to secure the area and prevent further environmental hazards. Traffic on I-95 northbound was completely shut down during the emergency response, but lanes were later reopened after crews cleared the scene.
Authorities have not yet released details on what caused the collision, and no information has been shared about additional injuries or involved parties. The incident remains under investigation.
Our thoughts are with the individual critically injured in this crash, and we hope for a full recovery.
Fiery Truck Collisions and Critical Injury Crashes on Florida Highways
The crash that occurred on January 4 near mile marker 307 in St. Johns County illustrates the significant dangers posed by semi-truck collisions on major Florida highways. In this case, a fire and a diesel fuel spill compounded the risk, leading to full lane closures and an airlifted trauma patient.
Semi-truck accidents can be particularly devastating due to the size and weight of the vehicles involved. When a fire ignites—as it did in this incident—the threat to life, property, and the environment increases dramatically. The fact that hazmat crews were needed highlights the severity of the crash and the complexity of the emergency response.
I-95 is one of Florida’s most heavily traveled corridors, serving as a primary route for both personal and commercial travel. High speeds, congestion, and the presence of large commercial vehicles create a volatile mix—especially when visibility is low or weather conditions deteriorate.
While the exact cause of this crash remains unknown, the resulting fire and critical injuries are reminders of how quickly serious incidents can unfold on interstates. Drivers are urged to use caution around commercial trucks, avoid sudden lane changes, and remain alert to changing road conditions.
