In 2011, 31% of fatal collisions involved which factor?

• A. Speeding
• B. Impaired driver
• C. Weather
• D. Mechanical failure

Answer: (B)

Impaired driving is the factor most strongly tied to that 31% figure because when a driver’s abilities are compromised by alcohol or drugs, reaction time, perception, and judgment are all reduced. This dramatically raises both the likelihood of a crash and the chance that a crash is fatal. Weather and mechanical failure can contribute to crashes, but they don’t align with the same single-factor prevalence as impairment. Speeding is a major risk, but the data point specifically highlights impairment as the factor involved in about one-third of fatal collisions.
