In most states it's a felony to modify or alter a drivers license, they are considered the property of the state and not yours personaly.
Next time a cop asks for ID and you hand him your d.l. you could be in for a lot more than couple hundred dollars and a ticket.
That's silly! I mess up my credit card strips all the time by keeping them in my pocket with keys on motorcycle rides, or in my tool belt when I used to do carpentry, or even slipping them into my money clip the wrong side out....the tape has never lasted longer than a month on any of my cards...I doubt, seriously, that a cop will harrass anyone who does not come out and say, "Yes, officer, I intentionally defaced my DL. And ya know why, Mr. Poleesse Man? Well, I'll tell ya <yadda, yadda, yadda, privacy, yadda, yadda, biometrics, yadda....>" I do agree that it is proably better to do the damage without it being noticable. Less suspicion is ALWAYS better. Best, -S
