Traction devices designed for vehicles with four-wheel drive enhance grip on snow and ice-covered surfaces. These devices typically consist of chains or cables wrapped around the drive wheels, providing increased contact with the road surface. For example, a truck navigating a mountain pass during winter would benefit from enhanced traction to prevent slippage.
Enhanced safety and mobility in challenging winter conditions constitute the primary advantage of these devices. They enable vehicles to maintain control and forward momentum on slick surfaces, reducing the risk of accidents. Historically, chains have been essential for traversing snowy or icy terrain, particularly before the advent of advanced all-wheel-drive systems and winter tires. They remain a vital tool for many drivers, especially those operating in regions with severe winter weather.
