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 equipped with safety features to prevent spills and leaks during transport. The design of tanker trucks varies based on their intended use. For example, fuel tanker trucks are specifically built to carry gasoline or diesel, while chemical tanker trucks are constructed to handle hazardous materials. Proper training and regulations are essential for drivers to ensure safe operation and compliance with industry standards.
