None of which will get you a not guilty verdict. Any and all pleas related to these sort of sign variations should always be a "guilty with an explanation" which is precisely what you're offering here. Doing so at the arraignment might get you a fine reduction. Wasting the court's time and the officer's time by going through TBD and maybe even a trial will likely negate any possibility of a reduced fine and possibly no longer having the traffic school option!
So, again, you're being inattentive and you think that is a lawful excuse!
What if it was a red light that you failed to notice? Do you think that will lessen your liability to any pedestrians that you ran over? Or to a diver /passenger of another vehicle that you broadsided?
