Car accidents are inevitable.  We all have one in some fashion in our lives but it is usually carelessness that leads to the more serious ones.  Sometimes there are accidents that are so serious that the fire department is called in to 

extricate the victims from their vehicle.  With today's technology: crumple zones, safety cages, side impact beams the passengers are more secure yes but it offers new challenges to firefighters when trying to rescue a victim from a vehicle.
