Which class of drivers showed the highest usage of safety belts?

Drivers of triple trailer trucks showed the highest usage of safety belts for several reasons. Typically, drivers operating triple trailer trucks are subject to stricter regulations and safety protocols due to the complexity and increased risk associated with handling multiple trailers. These drivers often have specialized training and are more aware of safety procedures, including the importance of wearing safety belts.

Additionally, triple trailer operation requires advanced skills and constant attention, which may contribute to a heightened emphasis on safety measures by the drivers. They are likely to understand that the consequences of not wearing a safety belt in such a large vehicle could be severe, motivating them to prioritize safety.

It is also worth noting that factors such as higher training requirements and a greater focus on compliance with safety regulations in the trucking industry might influence this behavior. These drivers may be more likely to adopt safety practices that protect not only themselves but also others on the road.
