RCW 46.61.055: Traffic control signal legend.
(a) Vehicle operators facing a steady circular red signal alone shall stop at a clearly marked stop line, but if none, before entering the crosswalk on the near side of the intersection or, if none, then before entering the intersection control area and shall remain standing until an indication to proceed is shown. However, the vehicle operators facing a steady circular red signal may, after stopping proceed to make a right turn from a one-way or two-way street into a two-way street or into a one-way street carrying traffic in the direction of the right turn; or a left turn from a one-way or two-way street into a one-way street carrying traffic in the direction of the left turn; unless a sign posted by competent authority prohibits such movement. Vehicle operators planning to make such turns shall remain stopped to allow other vehicles lawfully within or approaching the intersection control area to complete their movements. Vehicle operators planning to make such turns shall also remain stopped for pedestrians who are lawfully within the intersection control area as required by RCW 46.61.235(1).
