I was reading about the license plate obscuration covers and
their sometimes-ability to spoil the photo. In the case of the high-mounted I-520 cameras, the overhead-type diffraction grating type cover does sometimes work, but you are guaranteed the State Patrol will pull you over sometime because they are so easy to spot (the rectangle outline in the cover).
RE: I520 bridge.
I was in Seattle visiting the family between Christmas and New Years and considered trying it. I was driving a rental car with Illinois (?!) plates. I didn’t because you don’t want to mess with that stuff in a rental car. The company simply pays the fine and charges you. It’s an unbelievable hassle to do anything about it.
I need to check the WSDOT traffic maps. I can only assume I-90 is now a quagmire.
In my case the car had washington plates and I had a washington license. Then we changed the plates to Kentucky and went back to “that other state” and flew through the toll roads again. A month later we changed our drivers licenses to Kentucky. This state REALLY ties your car to you personally. The tabs expire on the month of my birth.
