The typical time window for many heavy vehicle crashes is between which hours?

• A. Midnight and 6 am
• B. Morning rush
• C. Afternoon
• D. Evening

Answer: (A)

Fatigue and limited visibility greatly raise the crash risk for heavy-vehicle drivers, especially during late-night hours. Between midnight and 6 am, drivers may be tired from long shifts or nighttime driving, and highway lighting is lower, which slows reaction times and makes it harder to see hazards. While rush-hour periods have heavy traffic, the period most associated with fatigue-related crashes for large trucks is the overnight window, making midnight to 6 am the typical time frame.
