NHTSA VIN decoder's GVWRClass field trips up developers

Original: NHTSA vPIC often returns a GVWR or GVWRClass field on DecodeVinValues-style payloads: catalog phrases... # typescript #

Developers working with the NHTSA vPIC VIN decoding API are noting that DecodeVinValues responses often include a GVWR or GVWRClass field, and that translating these catalog-style gross vehicle weight rating codes into user-facing labels is not straightforward. A write-up walks through displaying GVWRClass in a TypeScript project without inventing payload values that the API does not actually provide, a common pitfall when mapping government data codes to plain language.

Why now: Developers building vehicle lookup tools keep hitting ambiguous GVWRClass codes in the API and want reliable ways to display them
