Among collision types, which is considered the deadliest?

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

Answer: (C)

When two vehicles collide head-on, their speeds add together at impact, creating a much higher closing speed and a surge of energy to dissipate in an instant. That big energy transfer forces an abrupt, extreme deceleration on occupants, increasing the likelihood of fatal injuries to vital areas and greater intrusion into the passenger space. In comparison, side impacts, rollovers, and rear-end crashes can be deadly, but they generally involve less total energy or different intrusion patterns, making head-on collisions the most dangerous overall.
