speeding tickets

[hotdogon]

Does Washington State have presumed or absolute speed signs?
And is police policy to not ticket drivers who are accelerating up to a
faster speed zone once they can visibly see the faster speed limit sign and it is safe to do so?

As you describe this situation you clearly violated the speed limit. The speed limit changes after the sign, not before it. If you were accelerating to the sign you were likely exceeding the existing speed limit that extends to that point.
