Out of state speeding ticket points on Michigan freeway

In Michigan, speeding on a limited access freeway gets one less point than other speeding tickets. If you get a freeway speeding ticket in a state that doesn’t have separate ticket categories, would Michigan add it as a normal (non-freeway) ticket with the extra point? And if they do, could you challenge it?

Yes, states can reassess the points from out-of-state tickets through the interstate driver’s license compact. Not all states will carry points over, but most do, and they’re allowed to reassess the points according to their own system. You might be able to challenge the reassessment if Michigan assigns more points than what you would have gotten in the state where you received the ticket, so it could be worth talking to a local attorney.
