A reefer truck, also known as a refrigerated truck or a freezer truck, is a type of commercial vehicle equipped with a refrigeration unit to maintain a controlled temperature within the cargo area. These trucks are specifically designed to transport perishable goods, such as food, pharmaceuticals, flowers, and other items that require temperature-sensitive handling to prevent spoilage or degradation.

The refrigeration unit in a reefer truck allows the interior temperature to be regulated, ensuring that the cargo remains within the required temperature range throughout transportation. This is crucial for preserving the quality and safety of the transported goods.

The dimensions of reefer trucks are similar to those of standard commercial trucks, as the refrigeration unit is typically installed on the front section of the trailer or as a separate unit. In the USA, the general dimensions for reefer trucks are as follows:

Length: Reefer trucks come in various lengths, commonly ranging from around 48 feet (14.63 meters) to 53 feet (16.15 meters), similar to the length of standard dry vans.
Width: The width of a reefer truck is typically around 8 to 8.5 feet (2.44 to 2.59 meters), consistent with the standard width of most commercial vehicles.
Height: Like other truck types, the height of a reefer truck generally falls within the range of 12 to 14 feet (3.66 to 4.27 meters), but the height can vary based on the specific model and any additional equipment on the roof.

Reefer trucks are classified based on their Gross Vehicle Weight Rating (GVWR), which indicates the maximum weight a vehicle can carry, including its own weight. Various GVWR classes are available to accommodate different payload capacities.

Reefer trucks are essential for the transportation of temperature-sensitive goods across long distances, allowing perishable items to be delivered to markets and consumers while maintaining their quality and safety. These trucks are commonly used in the food industry to transport fresh and frozen products, as well as in the pharmaceutical industry to ensure the integrity of medical supplies.

Operators of reefer trucks must adhere to strict temperature control guidelines, proper loading procedures, and maintenance practices to ensure that the cargo arrives in optimal condition. Regulatory standards and best practices help prevent spoilage, maintain product quality, and ensure consumer safety.
