4x4 competitions are events where off-road vehicles, often referred to as 4x4s, are tested for their performance in challenging terrains. These competitions can include various formats, such as rock crawling, mud bogging, and obstacle courses, where drivers navigate through difficult landscapes to showcase their skills and vehicle capabilities. Participants in 4x4 competitions often modify their vehicles with specialized tires, suspensions, and other equipment to enhance performance. Events are typically organized by clubs or associations, and they attract enthusiasts who enjoy the thrill of off-roading and the camaraderie of fellow competitors.
