I don't have a front plate, so that won't work. The motorcycle headlight pass can't be removed, so I would get charged for using the Hot Lane on 167 even if I had passengers in the car. If you already have the movable Popsicle stick pass, try it on the top edge of the rear view mirror. I really think it will work there. Alternatively, register your license plate. It costs only 25 cents more to cross the bridge than having a pass.
