I'm looking for any laws regarding passengers in the bed of a pickup in NH. The only thing I can find that's close is the seatbelt requirement for those under 18.

As far as I can tell NH law is silent on the issue, but I'm no lawyer.

I got a ticket for passengers in a pickup bed in Maine few years ago and, after reviewing the laws, fought the ticket and it got thrown out. (Everyone under 18 was wearing a seatbelt and all seatbelts were being used which made it a non-violation in Maine.)

Any info guidance, help is appreciated.
