If the officer is proactive, window tint is the perfect tool to get a stop. It can give you a reason to begin an interaction that could lead to more. As a general rule, I don't write traffic tickets unless I need to. If there is more than a traffic infraction, I will call for a tint meter and write it as my PC for the stop. If not, you go on your merry way. However, I have a partner on Wednesday and Thursday who will write it almost every time. He views it as an officer safety issue (which it is). He issues the ticket and tells them that if they go to a professional to have it removed, then take the receipt to court, they will almost always dismiss the charge.
