What is a major cause of truck accidents?

1. Vehicle maintenance issues

2. Driver fatigue and inattention

3. Weather conditions only

4. Improper cargo loading

The correct answer is: Driver fatigue and inattention

Driver fatigue and inattention are major contributors to truck accidents because they directly affect a driver's ability to operate the vehicle safely. When drivers are fatigued, their reaction times slow down, decision-making skills diminish, and their attention to the road can wane, making it more likely for them to miss critical signs or hazards. This can result in careless errors such as not maintaining a safe following distance or failing to notice changing traffic conditions. Moreover, inattention can stem from various distractions, including mobile device usage or even daydreaming, amplifying the risks associated with driving large vehicles. The combination of fatigue and distraction can lead to serious accidents, which is why addressing these issues through safety training, regulations regarding hours of service, and promoting wellness can significantly enhance road safety for all users. While vehicle maintenance issues, adverse weather conditions, and improper cargo loading can certainly play significant roles in accidents, the pervasive nature of driver fatigue and inattention makes them a particularly critical focus in accident prevention strategies.
