The first edition of the Manual de Rotulación para las Vías Públicas de Puerto Rico was published in 1979. This manual was most recently updated in 2020.[1] Puerto Rico is among the territories of the United States to have adopted the national MUTCD in conjunction with a supplemental volume.[2] The inscriptions on road signs are written in Spanish since it is an official language of Puerto Rico and is most widely spoken in Puerto Rico.[3]
The suffix (D) in parentheses means "right", from Spanish derecha, while the (I) in parentheses means "left", from Spanish izquierda.
Regulatory signs
Regulatory signs give instructions to motorists, pedestrians, and cyclists. Signs including Stop, Yield, No Turns, No Trucks, No Parking, No Stopping, Minimum Speed, Right Turn Only, Do Not Enter, Weight Limit, and Speed Limit are considered regulatory signs. Some have special shapes, such as the octagon for the Stop sign.
R1 series: Stop and yield
The MUTCD's R1 series is for Stop and Yield. Although the 4-WAY plaque (R1-3) was deprecated in the 2009 Edition of the MUTCD in favor of the ALL WAY plaque (R1-3P), the 4-VIAS plaque (R1-3) is still used in Puerto Rico.
The MUTCD allows for three types of parking signs: permissive, No Parking, and No Standing. However, in most states, there is an additional more restrictive one, No Stopping. These signs are found in the R7 series of signs in the MUTCD. Permissive parking signs allow for parking for either an unlimited or varied amount of time. They are often used in conjunction with parking meters and parking permits. They are specified by the MUTCD to be green on white. Local variations occur with additional information and slightly different designs. No Parking signs indicate that loading or unloading while temporarily stopped is permitted, but the driver must not leave the vicinity of the vehicle.[4] Some No Parking signs display time restrictions, while others are permanent restrictions. There are also temporary versions of the signs, often of similar design to the permanent ones. These signs are specified by the MUTCD to be red on white, although local variations occur. No Standing signs indicate that stopping temporarily to load or unload passengers is allowed, but vehicles cannot be stopped at the location for longer periods of time, even if the driver remains with the vehicle.[4] As with no parking signs, some restrictions displayed on the signs are permanent, and some are time-based.

Warning signs
Warning signs are found in the W series of the national MUTCD. They highlight existing conditions, such as a curve, school, dead end street, or traffic signal. They can also warn of possible danger such as bumps, bicycles, low flying aircraft, or emergency vehicles. They are either yellow or fluorescent yellow in color and, with a few exceptions, are usually diamond-shaped and sometimes have square or rectangular smaller signs or plaques associated with them. Most W series signs can also be found with orange backgrounds for temporary use in situations such as construction zones. Some of the temporary-use signs are for use only in temporary situations.
