Tanker trucks are large vehicles designed to transport liquids, such as fuel, chemicals, or water. They have a cylindrical tank mounted on a truck chassis, allowing for efficient loading and unloading. These trucks are commonly used in industries like oil, agriculture, and construction. The design of tanker trucks includes safety features to prevent spills and leaks. Many are equipped with pumps for easy transfer of liquids and may have multiple compartments to carry different substances simultaneously. Proper training and regulations are essential for drivers to ensure safe operation and compliance with transportation laws.
