Here is the functional classification guidance from the FHWA. Missouri DOT and all others should be following this guidance when classifying roads. Keep in mind that the DOT is in place to manage the Highway System. In other words, we care about planning, funding, construction and maintenance of those systems. This may be a different perspective than someone who is using the highway system who might care more about navigation.

Or the myriad "highway=residential"s from TIGER that have lead to some bicycle routing engines to ignore highway=residential/tiger_reviewed=no in the US because they're often no more than dirt tracks. A good way to deal with such external data sets as discussed here is to massage them until they fit the objects on OSM, and then create a map showing where the state highway department appears to differ from what's in OSM (maybe using different colours for "their road class is higher than ours" and "their road class is lower than ours"). Then we and/or local mappers could investigate the differences and make adjustments where deemed sensible. And while our ODbL licensed data is probably not suitable for direct back-import into the state highway department's database, they might actually find such a comparison useful as well - maybe it can help them spot errors in their own data.
