Final answer:
Tanker trucks are prone to instability due to their liquid cargo. When transporting liquids, tanker trucks can experience sloshing, which can cause them to become unbalanced and potentially tip over.
Step-by-step explanation:
The term 'prone to' suggests that the question is asking about a characteristic or condition that tanker trucks are likely to have. One characteristic of tanker trucks is that they are prone to instability due to their liquid cargo. When transporting liquids, tanker trucks can experience sloshing, which is the movement of the liquid inside the truck that can cause it to become unbalanced and potentially tip over.
For example, when a tanker truck is filled with liquid, the liquid will shift as the truck accelerates, decelerates, or turns. This shifting of the liquid can create a destabilizing force on the truck, making it prone to instability. To mitigate this risk, tanker trucks are designed with baffles or compartments that help reduce the movement of the liquid and increase stability.
