Which statement about speeding in fatal crashes is true?

Answer: C — Approximately 30% of fatal crashes involve speeding.

The assertion that approximately 30% of fatal crashes involve speeding is grounded in statistical analysis and research conducted in traffic safety. Speeding is known to contribute significantly to the severity and frequency of accidents. When drivers exceed the posted speed limits, their stopping distance increases, and the impact force in a collision becomes greater, which elevates the risk of death or serious injury in crashes. Research by various traffic safety organizations highlights that a sizable fraction of fatal motor vehicle crashes can be linked to speeding, affirming that it is indeed a critical factor in road safety. This statistic serves to underline the importance of adhering to speed limits to ensure the safety of all road users. In contrast, the other statements downplay the relationship between speeding and fatal crashes. They suggest either an insignificant impact of speeding, a minor percentage of involvement in such crashes, or claim that speeding is less significant compared to other factors, which is not supported by the data on traffic incidents.
