CDL Tanker Endorsement Practice Exam

What does a high center of gravity in loaded tankers imply?

1. Most of the weight is low to the ground

2. Most of the weight is high up off the ground

3. The truck is unstable

4. The tank is almost empty

The correct answer is: Most of the weight is high up off the ground

A high center of gravity in loaded tankers indicates that a significant portion of the weight is positioned higher off the ground. This is particularly relevant for tankers, as a higher center of gravity can lead to challenges in maintaining stability, especially during turns or sudden maneuvers. In loaded tankers, if the cargo shifts or if the tanker is filled in such a way that the weight is distributed unevenly, it exacerbates the risk of tipping or losing control. While it is true that having a low center of gravity generally enhances stability, the scenario presented here emphasizes that the tanker has a high center of gravity, which compromises that stability. Understanding this concept is crucial for safe operation, as drivers must be aware that a high center of gravity may require them to adjust their driving techniques to compensate for the increased risk of rollover or handling difficulties.
