It’s legal to pass on the right here in MN. States should enforce left lane for passing only, but they don’t. This creates a situation where the left lane has effectively become the right lane and thus you can use the right to pass instead.

E: it is not legal to pass on the right in MN, unless you’re on a multi-lane road; which is basically all major arteries and thus makes this law unenforceable for all intents and purposes.

It generally isn’t even possible or useful to pass on the right if people follow the traffic laws of keeping right unless passing. It becomes necessary only when people are illegally hanging out in the left lanes going slower than the normal flow of traffic.
