• A. Rear-end collision.
• B. Side swipe.
• C. T-bone collision.
• D. Head on impact.

Answer: (D)

The main idea here is to minimize crash energy by avoiding the most dangerous type of crash. A head-on impact is the most dangerous because two vehicles collide front to front, so the speeds of both vehicles combine. That creates a large amount of energy that has to be absorbed by the occupants and the vehicle structure in a very short time, making severe injuries or fatalities much more likely. Because of this, the safest rule is to stay out of the oncoming lane and keep plenty of space to react—especially on curves, hills, or narrow roads where crossing into opposing traffic is more probable. If you can prevent a head-on crash, you dramatically reduce the potential for the most serious outcomes. The other crash types can still cause harm, but head-on collisions carry the highest risk, which is why avoiding them is the fundamental principle.
