No helmets required here in Delaware. But the funny thing is you have to carry one on the bike. That goes for a passanger too. What good it does to have it on the bike is beyond me. Like you are gonna grab it real quick and throw it on in a wreck. OoooooK. I actually got a ticket back in 88 for not having two helmets on the bike when I had a passanger. Neighboring PA just last year made helmets not mandatory. Maryland still sucks.
