"Multi-Axle" refers to vehicles that have more than two axles, which are the rods that connect pairs of wheels. This design is commonly found in larger vehicles like trucks, buses, and trailers. The additional axles help distribute weight more evenly, improving stability and reducing wear on tires. These vehicles are often used for transporting heavy loads, as the extra axles allow for greater weight capacity. Multi-axle configurations can enhance maneuverability and provide better traction, especially in challenging driving conditions. This makes them essential for industries such as construction and logistics.
