Jimmy did not directly get involved with the firefighters' rescue operations. Instead, he first assessed the situation of both vehicles, reconstructing the events based on information provided by witnesses and the tragic scene he observed.
Car A was driving in the proper lane, and Car B came from the opposite lane and suddenly cut into Car A's lane, causing a head-on collision.
The driver of Car B was confirmed dead, and the driver of Car A was the one firefighters had been rescuing, while the passenger of Car A had already been transferred to an ambulance.
From the scene, it was clear that Car B was fully at fault, but since the driver was already dead, the remaining information would likely have to be retrieved from the system.
