Which of the following is a factor that may contribute to a vehicular crash?

• A. Long hours of driving without rest
• B. Speed
• C. Vehicle color
• D. Blue sky

Answer: (B)

Speed directly affects both the chance of a crash and how severe it will be. When you’re travelling faster, you have less time to notice hazards and react, and you need a longer distance to stop. The energy involved in a crash also climbs with speed—kinetic energy grows with the square of velocity—so higher speeds mean more force hitting the vehicle and its occupants, leading to more damage and injuries. While other factors like fatigue from long hours can contribute to crashes, speed is the primary driver of both the likelihood and the harm of a collision. Vehicle color or a clear blue sky don’t influence crash risk in a meaningful way.
