Speed is a factor in what portion of fatal crashes?

Speed is a factor in what portion of fatal crashes?

• A. Over 30 percent.
• B. Between 5 and 10 percent.
• C. Below 20 percent.
• D. Exactly 50 percent.

Answer: (A)

Speed influences both how likely a crash is and how severe it can be. Police crash data consistently show that speed-related factors appear in a substantial portion of fatal crashes—roughly a little over 30 percent. That’s because higher speeds increase crash energy (kinetic energy grows with speed squared), which dramatically raises the risk of a fatal outcome. Faster driving also extension stopping distance and reduces the driver’s ability to react to hazards, especially in adverse conditions or on curves. So, the best way to describe the impact is that speed is a factor in just over 30 percent of fatal crashes. The other figures don’t match what the data typically show: far fewer than half, and far more than a few percent.
