Which of the following is considered a driver behavior factor during crash investigations?

• A. Vehicle Color
• B. Insurance Status
• C. Nervousness
• D. Weather Conditions

Answer: (C)

Driver behavior factors describe how a driver acts behind the wheel and how that behavior can influence a crash. Nervousness reflects the driver's emotional state and can affect perception, risk assessment, and reaction time, all of which influence how controls are used and how quickly a driver responds to hazards. In crash investigations, factors are grouped into driver behavior, vehicle factors, and environmental conditions, and nervousness fits squarely under driver behavior because it describes the driver’s actions and mental state while driving. By contrast, vehicle color is a vehicle attribute and doesn’t describe driving actions; insurance status is administrative information about the policy; and weather conditions are environmental factors that affect driving but aren’t actions taken by the driver.
