Final answer:
To haul dangerous goods, a driver needs to have a Hazardous materials endorsement on their commercial driving license, not just a regular license or a defensive driving certificate.
Step-by-step explanation:
In order to haul dangerous goods, a driver must obtain a Hazardous materials endorsement (HME) on their commercial driving license. Just a regular driver's license is not sufficient. The endorsement involves additional training, a background check, and a test on handling hazardous materials. This ensures that individuals are prepared to manage and transport these items safely and are aware of the regulations and procedures that pertain to hazardous materials. It's important to check the specific requirements as they can vary by country and region. A defensive driving certificate and a special license might be beneficial or required for other aspects of driving, but specifically for hauling dangerous goods, the HME is the key requirement.
