According to prevailing research, single-vehicle crashes are how many times more likely to occur during nighttime hours?

• A. 5x
• B. 25x
• C. 10x
• D. 2x

Answer: (B)

Nighttime driving brings visibility challenges, glare, fatigue, and a higher likelihood of impairment, all of which dramatically raise crash risk. Research shows single-vehicle crashes are about 25 times more likely to occur at night than during daylight. This large difference reflects how reduced visibility and compromised driver condition increase the chance of losing control, running off the road, or hitting roadside hazards without another vehicle involved. The other options underestimate how much risk rises at night. When driving at night, slow down, increase following distance, ensure you’re rested and sober, and use headlights properly to improve detection and reaction time.
