MUTCD/Puerto Rico

PRHTA-specific signs

The Manual de Rotulación para las Vías Públicas de Puerto Rico (Spanish for "Sign Manual for the Public Roads of Puerto Rico") is Puerto Rico's supplement to the MUTCD, the standard for road signs, signals, and markings in the United States. It is developed by the Puerto Rico Highways and Transportation Authority (PRHTA) "in substantial conformance to" the national MUTCD developed by the Federal Highway Administration.

The sign manual contains design specifications for road signs, complementing the national Standard Highway Signs and Markings document. The latest edition of the sign manual was published in 2020 (as of April 2022).

Usage in OpenStreetMap

A traffic sign specific to the sign manual is mapped as a node tagged traffic_sign=US:PR:Z1-2, where "US:PR" is Puerto Rico's ISO 3166 code and Z1-2 is the sign's alphanumeric designation.

Sign designations

Each standard sign or plaque in the sign manual is assigned an alphanumeric designation and organized by series. A sign designation follows the same format as in the national MUTCD and SHSD; however, the sign designation for a state-specific sign is indicated by a "(PR)" after the sign number. This suffix is omitted from the traffic_sign=* value because it is usually redundant to the "US:PR" namespace, with a few exceptions.


Category	Series		Sign	Variant	Position	Orientation
R	12	-	7	a
Regulatory	Weight Limits		Non-Emergency Vehicle Weight Limit	Single Axle and Tandem	(Not a plaque)	(Normal)

Unlike in the national standard, the orientation is abbreviated according to Spanish: "I" for left (izquierda) and "D" for right (derecha).
