Typically state DOT functional classification freeway and expressway both imply limited, but not necessarily fully controlled, access, so trunk is a good first approximation. However, the DOT classification diverges enough from OSM tagging standards/consensus (such as it is in the US, anyway) that using it as anything more than a basic reference where decent satellite imagery and ground truth observations are unavailable is a bad idea.
It's better than nothing when looking at unreviewed stuff from the TIGER import, for sure, but that's about it.
