Some states take it one step further and let motorcycles go through a light that won't change for them. I don't think Oregon is one of those states, either for motorcycles or bikes. I've dealt with this a few ways:

-Just waited for a car.
-I've taken a right and made a u-turn if traffic is light. I think this might actually be legal in some spots.
-I've caved and hopped on the sidewalk to push the walk button, but then you're faced with the awkwardness of getting back in the lane.
-I've run the stop light by going through both crosswalks, but I don't think that gets me out of any legal issues, but it seemed like it might.

I was faced with this problem once and checked over my shoulder before running the light. Upon gazing behind me I noticed a cop coming up, so I stopped. The cop stopped behind me, but gave me so much room he wasn't on the sensor either. We waited and waited until a car coming the other way rolled up to the other side of the intersection and the light eventually changed. It was annoying.

What intersection?
