Rhode Island General Laws Title 31. Motor and Other Vehicles § 31-19-15. Left turns

(a) A person riding a bicycle intending to turn left shall, unless he or she complies with the provisions of § 31-16-2, approach the turn in a position as close as practicable to the right-hand curb or edge of the roadway. The turn shall be made at a position as close as practicable to the right-hand curb or edge of the roadway along which the bicyclist intends to proceed after turning.

(b) If the turn is made at a location where traffic movement is controlled by a police officer or by a traffic-control signal, the bicyclist may not proceed after crossing the intersecting roadway until a signal to proceed is given to traffic moving in the appropriate direction on the roadway along which the bicyclist intends to proceed. At all other locations, after turning and before crossing the roadway he or she is leaving, the bicyclist must yield the right-of-way to all traffic approaching on that roadway.

(c) The state highway commission and local authorities in their respective jurisdictions may cause official traffic-control devices to be placed and require and direct that a specific course be traveled by turning bicycles, and when the devices are so placed, no person shall turn a bicycle other than as directed and required by the devices.
