Definition:
A caterpillar track is a type of moving belt made of metal that helps vehicles, like tanks and bulldozers, move across the ground. It’s called a "caterpillar" track because it looks a bit like a caterpillar moving along the ground.
In more technical discussions, you might refer to how the design of the caterpillar track allows for better weight distribution, making it easier for vehicles to travel on soft or uneven surfaces.
While there aren't specific idioms or phrasal verbs that include "caterpillar track," you can use phrases related to movement, such as: - "Hit the road": To start a journey, though this is more casual and does not relate directly to caterpillar tracks.
A caterpillar track is an important part of certain vehicles that allows them to travel over different types of terrain.
