Which type of collision is the deadliest?

• A. Head-On
• B. Rear-End
• C. Side impact
• D. Rollover

Answer: (A)

Head-on crashes are the deadliest because the closing speed is the sum of both vehicles’ speeds, creating enormous deceleration forces on the occupants. The crash energy has to be absorbed almost instantly by the vehicle structure and restraints, often causing severe intrusion into the occupant area and a high risk of fatal injuries to drivers and front-seat passengers. Other crash types can be extremely dangerous, but the combined energy and abrupt stopping in a head-on collide produce the greatest potential for catastrophic injuries per incident.
