Heavy vehicles are large motorized machines designed for transporting goods, materials, or people. They include trucks, buses, and construction equipment like excavators and bulldozers. These vehicles are built to handle heavy loads and often have powerful engines to provide the necessary strength and durability. Due to their size and weight, heavy vehicles require special licensing and training for operators. They are commonly used in industries such as transportation, construction, and mining. Safety regulations are crucial to ensure the safe operation of these vehicles on roads and job sites.
