General guidance
A small open utility trailer is the vehicle most likely to be exempt from registration in some states — but that exemption usually has a weight cutoff, and it is easy to assume you are covered when you are not. Pick your state below to see the real rule.
This is the single most common source of confusion with utility trailers. A state may exempt trailers under roughly 1,500–3,000 lb gross weight (the exact number varies by state) while requiring registration above that line. The state guide below states the actual rule where it has been sourced from the agency.
Some states that exempt light trailers from annual registration still require the trailer to carry a permanent, state-issued serial number or a one-time title. Do not assume "no registration" means "no paperwork at all" without checking the state page.
A used utility trailer needs the title or registration transferred into your name, which is a different (usually simpler) process than a first-time registration. The agency contact in the state guide handles both.

In several states, yes — but the exact weight and whether it is empty weight or gross weight varies by state. The state guide below states the sourced rule where it has been verified; never assume your trailer is exempt without checking.
That also varies by state and sometimes by weight class — some states title every trailer, others only title trailers above a weight threshold, and some never title light utility trailers at all. Check the state guide below for the sourced answer.
