Vehicle class

Specialty: optional-design programs on standard serials (US state programs). Issued for car, van, truck, and motorcycle.

Size

12 × 6 in (305 × 152 mm) · every country's size

About this plate

The count is AGENCY-SOURCED ("over 40", ITD's own words), which is stronger than Oregon's (unpublished) and Wyoming's (enumerated but not totalled), though weaker than Washington's (a statutory table). Two follow-ups are pinned and both are cheap: IDAPA 39.02.60, which is the real rule set, and the Interactive Plate Programs Guide, which may be a structured endpoint.
