Vocational Vehicle
In trade usage, a truck configured for a working task rather than hauling freight. In EPA regulation it is a narrower defined category based on weight and on not being a tractor.
Two meanings are in circulation and they are not the same, which is worth knowing before quoting either in a specification.
In everyday fleet use, a vocational vehicle is a truck built around the work it does rather than around carrying a load: a dump body, a refuse packer, an aerial device, a sewer unit, a plow and spreader configuration.
In EPA greenhouse gas regulation, at 40 CFR 1037.801, it is a defined residual category: “a heavy-duty vehicle at or below 26,000 pounds GVWR that is not subject to standards under 40 CFR part 86, subpart S, or a heavy-duty vehicle above 26,000 pounds GVWR that is not a tractor.”
The regulatory version is defined largely by what a vehicle is not, and it turns on weight and tractor status rather than on the body or the work. A vehicle can therefore be vocational in the yard and not vocational in a compliance filing, or the reverse.
