Texas CDL General Knowledge Practice Exam

Which of the following statements is true about heavy vehicle accidents?

1. A. They mostly occur during rush hour

2. B. They mostly occur on weekends

3. C. They mostly occur between midnight and 6 AM

4. D. They mostly occur during sunny days

The correct answer is: C. They mostly occur between midnight and 6 AM

The statement that heavy vehicle accidents mostly occur between midnight and 6 AM is supported by various studies and statistics related to vehicle accidents. This time frame often features reduced visibility and potentially fatigued drivers, contributing to an increased risk of accidents involving heavy vehicles. Additionally, the lower volume of traffic during these early hours can sometimes lead to more severe outcomes when accidents do occur, as vehicles may be traveling at higher speeds without the usual congestion. In contrast, the other options do not reflect the general trends observed in accident data. While rush hour typically sees a high volume of vehicles, heavy vehicle accidents tend to be more prevalent during hours when fewer vehicles are on the road, making nighttime and early morning hours more risky. Similarly, weekends may have varying patterns depending on traffic conditions, and accidents on sunny days are often less common than those occurring in adverse weather when visibility and road conditions decline.
