What percentage of all highway fatalities, according to DOT statistics, result from secondary crashes?

The correct answer identifies that 18% of all highway fatalities result from secondary crashes, according to Department of Transportation (DOT) statistics. This statistic highlights the critical importance of understanding not only the primary incidents that lead to accidents but also the subsequent crashes that occur as a result of the initial event. Secondary crashes often happen due to factors such as reduced visibility, sudden stops by other vehicles reacting to the primary incident, or the presence of first responders on the scene. Recognizing that almost one-fifth of fatalities are the result of these secondary incidents underscores the need for proper safety measures, strategic traffic management, and public education to mitigate the risks associated with them. Proper training for emergency responders and highway safety protocols can significantly reduce the occurrence of these secondary crashes.
