San Marino license plate, Trailer R (documented since 1986), sample R2871

Format, years and the law

Format
R9999, for example R2871 (9 any digit)

The leading R marks a trailer, numbered from 900 upward. Small tag-along carrelli get no number of their own, just a repeater plate copying the towing car's, stamped with a tiny red R, 21 millimetres tall.

The format above follows the issuing rules: a registration that fits it is one this series could have issued.

Years issued
Documented since 1986; the format is likely older than the first year documented. Still issued.
Vehicle class
Trailer: trailers and semi-trailers where separately serialized. Issued for trailer and semitrailer.

About this plate
TRAILERS. Numbering opened at 900 (Decreto 151/1986 art. 4). A separate REPEATER plate exists for carrelli appendice, a small red R, 21 mm high and 11 mm wide, on a plate repeating the towing vehicle's number (art. 2 lit. d, and Legge 23/1989 art. 13).
Format notes
Decreto 151/1986 art. 2 lit. c: "Per i rimorchi i numeri di immatricolazione sono preceduti dalla lettera 'R' a rilievo di colore rosso dell'altezza di mm. 79, larghezza mm. 45 e con il tratto di mm. 12,5." This is why R is excluded from the ordinary alphabet, a FUNCTIONAL reservation, not a legibility exclusion.
