Amphibious vehicles are specially designed to operate both on land and in water. They combine features of traditional vehicles, like cars or trucks, with those of boats or ships. This versatility allows them to navigate various terrains, making them useful for military operations, rescue missions, and recreational activities. These vehicles often have buoyant bodies and propellers or tracks that enable them to transition smoothly between driving on roads and floating on water. Examples of amphibious vehicles include the DUKW, a World War II-era military truck, and modern amphibious ATVs used for outdoor adventures.
