Off-road vehicles are designed to navigate rough terrain and challenging landscapes, and they come in a variety of shapes and sizes. Here are some other words you can use to describe these vehicles: 1. All-terrain vehicle (ATV): An ATV is a four-wheeled vehicle that's designed to handle all types of terrain. It's often used for recreational purposes, but it can also be used for work purposes. 2. 4x4 vehicle: A 4x4 vehicle has four-wheel drive, which means that all four wheels can receive power from the engine. This makes it easier to navigate rough terrain. 3. Mud buggy: A mud buggy is a lightweight off-road vehicle that's designed for mud and water. It usually has oversized tires and a snorkel to allow it to drive through deep water.
