## About this plate

TRAILER. Kept as its own series because Montana gives it a size rule, a county-prefix consequence and a permanent-registration legend that the passenger plate does not have. The declared-weight size split is the single best example in this group of a US state making the PLATE FORMAT depend on a vehicle attribute plus an owner election.
