How does higher speed affect crash risk in a pursuit?

• A. It reduces the risk of a crash.
• B. It eliminates the risk of injury.
• C. It has no effect on crash risk.
• D. Higher speed increases crash risk.

Answer: (D)

Speed is the key factor in crash risk during a pursuit. When you drive faster, the distance needed to stop or avoid a hazard grows quickly: braking distance increases roughly with the square of speed, and the distance covered during the driver's reaction time grows in direct proportion to speed. That means at higher speeds you have less time and space to react to sudden obstacles, other vehicles changing lanes, or a curve ahead. Beyond stopping distance, the vehicle carries more kinetic energy at higher speeds, so any collision tends to be more severe and control becomes harder. In a pursuit, these issues are amplified by traffic, road conditions, and unpredictable behavior from other drivers or pedestrians. The combination of reduced reaction time, longer stopping distances, and greater crash severity makes higher speed increase crash risk. So, higher speed increases crash risk.
