Which factor can increase the risk associated with transporting hazardous materials?

Inexperienced drivers significantly increase the risk associated with transporting hazardous materials due to a lack of knowledge and skills necessary to handle dangerous situations. They may not fully understand the specific properties of the materials they are transporting, which is critical for responding appropriately in emergencies. Additionally, inexperienced drivers are more likely to make poor judgment calls when faced with unexpected challenges on the road, such as adverse weather conditions or vehicle malfunctions. Their lack of familiarity with safety protocols and regulations can lead to accidents or spills that put themselves and others at risk. In contrast, well-trained drivers who are experienced in hazardous material transport understand the importance of safety measures, regulations, and best practices to minimize risks.
