GEThttps://trucktabs.com/api/v1/jurisdictions/{code}/limits

A state's legal size and weight limits and its permitting offices. A load over any of these limits needs an oversize/overweight permit in that state. Dimensions are in inches and weights in pounds. limits is null when we have nothing on file, which is not the same as no limit. An unknown code is 404 NOT_FOUND.

Send the code. The name and the aliases are accepted too, in any case and with any punctuation. An unknown word is refused, never guessed. tractor_trailer and truck_trailer are semis, which need a trailer type, trailer length and axles per unit. Every other type needs total axles and an overall length.

Every error has the shape { "error": { "code", "message", "details" }, "request_id" }. New codes may be added for new situations; an existing code never changes meaning. An unsupported method gets 405 with an empty body.
