## About this plate

PERMANENT TRAILER IDENTIFICATION. Recorded because California moved trailers to a PERMANENT registration in 2001 (reported) and because the predecessor, trailer plates with AT through HT prefixes, 1982-2001, is a dead series still lawfully on the road, the same shape as Florida's "Collectible" plate. Neither the current format nor the transition date is agency-sourced; both are recorded as gaps.
