Washington started flat-screening specialty plates in March 2005. That included WSU alumni (which had been embossed since their initial release in 1997), Vanpool, vanity and others. The background color scheme did not change at the time and the number font closely matched the dies used on prior embossed plates. Vanities available on specialty types with a different Montana-style font starting in 2008. Most specialty plates were subsequently redesigned.
Frank Astalosh advised that Trailer plates are available for specialty types with numbering starting at 90000.
Mike Kraft advised that Motorcycle plates are available for specialty types with numbering starting at 95000.
