Refrigerated vehicles are specially designed trucks or vans that maintain low temperatures to transport perishable goods. These vehicles are equipped with refrigeration units that keep items like fruits, vegetables, meat, and dairy products fresh during transit. The use of refrigerated vehicles is essential for the food industry, as they help prevent spoilage and ensure food safety. By controlling the temperature, these vehicles extend the shelf life of products and allow for longer-distance transportation, making them vital for grocery stores and restaurants that rely on fresh ingredients.
