Which is the primary purpose of a crush zone in a vehicle?

• A. To absorb energy during a collision
• B. To increase speed
• C. To reduce weight
• D. To dissipate heat

Answer: (A)

Crush zones are designed to deform in a controlled way when a collision happens so they absorb a large portion of the impact energy. By allowing the front and other sections to crumple, the vehicle decelerates more gradually, increasing the time over which the crash occurs and reducing the peak force transmitted to occupants. This helps protect people inside. It isn’t about increasing speed, reducing weight, or mainly dissipating heat; heat is a byproduct of the energy absorption process, not the primary goal.
