4x4 trucks are vehicles designed with four-wheel drive systems, allowing all four wheels to receive power from the engine simultaneously. This feature enhances traction and stability, making them ideal for off-road driving and challenging terrains, such as mud, snow, or rocky paths. These trucks often come equipped with robust suspensions and higher ground clearance, which help them navigate obstacles more effectively. Popular models include the Ford F-150, Chevrolet Silverado, and Toyota Tacoma, each offering various configurations and features to suit different driving needs and preferences.
