What is the weight threshold that classifies an apparatus as heavy versus light fleet?

The classification of apparatus into heavy and light fleet primarily depends on their weight. A weight threshold of 26,000 lbs. serves as a standard marker in many fire service classifications that designate whether a vehicle is considered part of the heavy fleet or light fleet.

Vehicles that weigh less than this threshold are categorized as light fleet, which typically includes smaller, more maneuverable vehicles that can be deployed quickly in urban settings. In contrast, those over the 26,000 lbs. mark are classified as heavy fleet, which generally consists of larger apparatus such as fire engines and ladder trucks that are equipped for more extensive firefighting needs.

This weight categorization is crucial for operational planning, as it influences compatibility with different types of emergency responses and the infrastructure they operate in, including weight limits on roadways and bridges.
