P.R. Laws tit. 9, § 5166
Any signal for turning in a public road shall be made continuously along a one hundred (100) feet length of the public road immediately before turning.
Any turn made on a public road shall be preceded by a gradual slowing down of the vehicle and by taking the following precautions:
(a) The driver of a vehicle intending to turn right shall, from a distance of not less than one hundred (100) feet before turning, approach the right hand curb or sidewalk of the roadway and make the turn along the border of said curb or sidewalk.
(b) Any person driving a vehicle who intends to make a left turn in a two-way traffic public road shall keep close to the center of the roadway, or when there is more than one (1) lane going in the same direction, to the extreme left-hand lane. The maneuver required in this subsection shall be made at least one hundred (100) feet before reaching the intersection.
(c) On one-way public roads with two (2) or more lanes, the driver shall take the extreme left-hand lane. The maneuver required in this subsection shall be made at least one hundred (100) feet before reaching the intersection.
(d) In all cases, after entering the intersection and provided it is practicable, a left turn shall be made on the left of the center of the intersection. After making the turn and entering the new roadway, the driver shall take the extreme left-hand lane lawfully available to traffic traveling in this direction.
(e) No turn may be made to proceed in the opposite direction when such a turn is prohibited by a special signal authorized by the Secretary, or in a school zone, or at a distance of less than five hundred (500) feet from a curve or the top of a grade of a public road hindering visibility or because a vehicle is approaching.
(f) No turn may be made to change direction by using the entrance to a private garage in the urban zone, except on dead-end streets lacking a turning area.
(g) No turn may be made before reaching an intersection by driving through an area devoted to the sale of gasoline, a parking lot or a vacant lot or any other activity conducted at a corner of an intersection, so as to thus evade traffic lights, any other traffic signal or the presence of a law enforcement officer or to get ahead of other vehicles.
(h) Notwithstanding the provisions of subsections (a) and (b) of this section, the Secretary and the local authorities regarding public roads under their jurisdiction, may authorize the use of more than one (1) traffic lane from where left or right turns may be permitted by markings to that effect on the pavement or sign within or adjacent to an intersection.
Any person who violates the provisions of this section shall incur an administrative fault and be punished with a fine of twenty-five dollars ($25).
