Which factor contributes to a crash according to the CR-100?

The correct answer encompasses all listed factors—weather conditions, driver distraction, and alcohol consumption—because each of these elements can independently increase the likelihood of a crash.

Weather conditions can greatly influence driving safety; for instance, rain, snow, or ice can reduce traction or visibility, making it more difficult for drivers to control their vehicles.

Driver distraction includes anything that diverts a driver's attention from the road, such as using a mobile phone, eating, or adjusting the radio. Distractions can significantly impair a driver's reaction time and awareness of their surroundings.

Alcohol consumption affects a person's cognitive and motor skills, impairing judgment, coordination, and reaction times, which can lead to an increased risk of accidents.

Thus, when the CR-100 considers crash factors, it acknowledges that each of these contributes to the likelihood of a crash, emphasizing the importance of recognizing and mitigating these risks to enhance road safety. This comprehensive view highlights the multifaceted nature of crash causation.
