About this plate

Every standard design first issued from 1989 onward remains orderable in parallel, indefinitely, and 61-3-332(3) extends the same rule to collegiate, generic specialty, commemorative centennial and military/veteran plates. A "previous base" in the sense the L2 brief means, a design that stopped, DOES NOT EXIST IN MONTANA LAW. Recording that with the citation is more accurate than minting a superseded series from a collector table, and it is a genuinely different jurisdiction shape from Oregon (one frozen base) or Washington (serial base changes with no legal marker).

How numbers are issued

MCA 61-3-332(6)(b) states the rule for EXEMPT plates explicitly, numbering 'must begin with number one and be numbered consecutively' within each county.

Separators

MCA 61-3-332(5) requires "a separation mark" and DOES NOT NAME A GLYPH. SEPARATELY AND IMPORTANTLY: the current base is reported to print a BUFFALO SKULL device in the separator position. A skull is not punctuation.

Replacement

years: 5. statutory text: MCA 61-3-332(3)(a)(ii)(A): 'Except as provided in subsection (3)(a)(ii)(B), license plates issued on or after January 1, 2010, must be replaced with new license plates if, upon renewal of registration under 61-3-312, the license plates are 5 or more years old or will become older than 5 years during the registration period. New license plates must be issued in accordance with the implementation schedule adopted by the department under 61-14-101.'. veteran exception: MCA 61-3-332(3)(a)(ii)(B): 'License plates issued to a disabled veteran with a combat-related disability must be replaced with new license plates if, on renewal of registration under 61-3-312, the license plates are 10 or more years old or will become older than 10 years during the registration period.'. number retention: MCA 61-3-332(3)(a)(iii): 'A vehicle owner may elect to keep the same license plate number from license plates issued before January 1, 2010, when replacement of those plates is required under this subsection.'. exemptions: MCA 61-3-332(3)(d): the replacement rule does NOT apply to a travel trailer, motorcycle, quadricycle, trailer, semitrailer or pole trailer at all. (3)(b): a vehicle registered for 13 to 24 months may display the design in effect at registration for the whole period. (3)(c): permanently registered light vehicles and motor homes may display the design in effect at registration for the whole permanent period, i.e. FOREVER.. note: MONTANA LEGISLATED BELOW AAMVA'S FLOOR. AAMVA recommends a cycle not exceeding 7 to 10 years; Montana chose 5. But read (3)(c) with it: a permanently registered light vehicle keeps its design indefinitely, so Montana simultaneously runs the group's shortest replacement clock and an unbounded exemption from it.
