Yes we get it, we could go to jail for wearing a non dot sticker'ed helmet.. Or maybe if our plates are tucked slightly, or maybe if we're using non dot turn signals or non dot headlight bulbs, or if we go slightly above the speed limit with our sport bikesBecause a cop doesn't cite you for it, doesn't make it less illegal - just means its your lucky day. I would not recommend printing a DOT sticker and adding to a helmet, that constitutes fraud and in the case of DOT regulations, is a Federal (not State) offense. Might seem a trifle, but I wouldn't want to risk going to the pokey over a helmet. Are we being robbed? In many cases, yes. The proper way to address the issue is by writing your Congressman.
But no need to write this non-issue to our congressmen (are you serious), there are far more important issues out there than this lmao.
