The victim should be moved out of the vehicle to a safe place only when there is an immediate danger, such as an explosion. With serious injuries, moving them can do more harm, and if an electrical wire has fallen on the vehicle, the people inside must stay there to avoid electric shock.
The victim should be taken out of the vehicle only when there is an immediate, life-threatening danger, such as a fire or an explosion. If there is no immediate danger, moving them without medical skills can make hidden injuries worse, especially to the spine.
Option 1. Moving a victim with serious injuries without proper equipment can make their condition much worse, especially if the spine is injured.
Option 3. If an electrical wire has fallen on the vehicle, touching the vehicle and the ground at the same time while getting out will cause an electric shock; it is safer to stay inside.
