I installed this and realized the cops would pull me over for obstructing the plate.
what i did was placed super glue quickly over each number on the plate then quickly pressed the super protector onto the plate this allows clear viewing of the plate from behind....but still affords protection since go angle and its blocked.
I dont know if this inpeeds its function...but I dought it...and I think it will keep me from being pulled over for a blocked plate.
Without the super glue...you cant see the numbers at all...haha. The super protector is the strongest plate protector.
