Which of the following is a key factor in preventing accidents in haulage systems?

Proper track maintenance is a fundamental aspect of preventing accidents in haulage systems. Well-maintained tracks ensure safe and efficient movement of vehicles, reducing the risk of derailments, collisions, and other incidents that may arise from poorly maintained infrastructure. Regular inspections and timely repairs can address potential hazards such as track misalignment, surface degradation, and inadequate drainage, all of which can lead to accidents.

While driver experience, truck size limitations, and visibility of safety signs play roles in overall safety, they don't directly address the structural integrity and operational reliability of the track system itself. Driver experience can improve safety behavior, but even the most skilled driver cannot compensate for a compromised track. Similarly, while truck size and visibility are important considerations, they are secondary to ensuring that the tracks themselves are in optimal condition to support safe haulage operations. Therefore, proper track maintenance stands out as the key factor in accident prevention within these systems.
