CDL Tanker Endorsement Practice Exam

When hauling hazardous materials, when should you check any dual tires?

1. Once a week

2. At the start of each trip and each time you stop

3. Only if you notice a problem

4. Before long hauls only

The correct answer is: At the start of each trip and each time you stop

The correct choice emphasizes the necessity of proactive safety measures when dealing with hazardous materials. Checking dual tires at the start of each trip and every time you stop is crucial for maintaining the vehicle's integrity and ensuring safety on the road. Frequent inspections allow you to identify any issues, such as low air pressure, uneven wear, or damage, before they can lead to more significant problems. This is especially important when you are hauling hazardous materials, where the consequences of a tire failure can be catastrophic, potentially leading to leaks, spills, or accidents that could harm people and the environment. The rationale behind inspecting the dual tires before starting a trip and during stops is to ensure that the tires are in optimal condition throughout the journey. This practice reduces the risk of breakdowns and enhances overall road safety, highlighting the importance of vigilance when transporting dangerous goods.
