Final answer:
C) You come to a complete stop and it is safe to do so. In Washington, a right turn on a red light is permitted after coming to a complete stop and ensuring it is safe to proceed, unless a 'No Turn on Red' sign is posted.
Step-by-step explanation:
In Washington (WA), you are allowed to make a right turn on a red light under certain conditions. You may make this turn only after you come to a complete stop at the red light, check for and yield to pedestrians and all other traffic, and determine it is safe to do so. The correct option from the ones provided is C) You come to a complete stop and it is safe to do so.
Option A) is incorrect because if there is a "No Turn on Red" sign present, you must wait for a green signal before making a turn. Option B) is partially correct; while the intersection must be controlled by a traffic light, it does not give the unilateral right to turn on red. Option D) is irrelevant because the presence of other vehicles is not the sole determining factor for whether a right turn on red is permissible. Additionally, exceptional circumstances, such as an emergency where a pregnant woman in labor is being rushed to the hospital, may necessitate breaking traffic laws. However, this is outside the norm and typically requires a justifiable emergency reason to be legally defensible.
