Not really looking for legal advice and I do know what the helmet requirements are in NJ, at least in practice if one gets pulled over. This is more about how the law is vaguely written and where one is supposed to find out how to go by the book when the book wants you to find information somewhere else.
From the relevant part of the relevant NJ statutes, Title 39 Section 39:3-76.7
6. a. A person shall not operate or ride upon a motorcycle unless the person is wearing a securely fitted protective helmet of a size proper for that person and of a type approved by the chief administrator. A helmet shall be equipped with either a neck or chin strap and be reflectorized on both sides thereof. The chief administrator is authorized and empowered to adopt rules and regulations covering the types of helmets and the specifications therefor and to establish and maintain a list of approved helmets which meet the specifications as established hereunder.
39:3-76.8. Goggles or face shield to be worn by motorcycle operator
No person shall operate a motorcycle unless he wears goggles or a face shield of a type approved by the director.
39:3-76.9 - Wind screen; goggles, face shields not necessary.
8. The provisions of section 7 of P.L.1967, c.237 (C.39:3-76.8) with respect to goggles and face shields shall not apply to the operator of a motorcycle equipped with a wind screen or an autocycle that meets the specifications established by the chief administrator.
So it’s got to be a helmet that fits well, has a neck or chin strap, be reflectorized on both sides and be approved by the chief administrator. Yet there are no links and no other helmet laws that describe what kind of helmets are approved by the chief administrator or who this administrator administrates. Some guessing and I was able to find through a search that the NJ Motor Vehicle Commission has a chief administrator, so I guess it’s her, but nowhere can I find where it’s her that explains what is approved. Again, I do know what is expected of us as I’ve been a part of the NJ motorcycle community for a long time and I know what cops expect and what riders get tickets for, and it says in the NJ Motorcycle manual and the driver’s manual:
HELMET SELECTION Approved helmets come in three types: one-half, three-quarter and full face. Each must: • Meet U.S. Department of Transportation (USDOT) Federal Motor Vehicle Standard (FMVSS) 218. Look for the DOT symbol on the outside back of the helmet. Then, look for a label inside the helmet with the manufacturer’s name, month, and year of manufacture, construction materials, model, size, and other important information. • Be equipped with a chinstrap and have at least four square inches of red, amber, or white reflectorized tape on each side. • Lack obvious defects, such as cracks, loose padding or frayed straps.
When riding, keep the helmet securely fastened at all times. A loosened helmet is likely to fall off during a crash.
So a cop would want us to wear a DOT approved helmet of the three types listed, but a manual isn’t a binding and those aren’t laws. I know NO ONE that wears a helmet with large goofy reflectorized tape on the sides nor do I know of anyone that got pulled over for that reason or got a ticket for it, nor can I find any evidence that that’s needed by the chief administrator. I’ve asked two NJ police officer acquaintances of mine if they were aware of the reflectorized tape necessity and they weren’t.
Could I technically get a ticket for not having reflectorized tape on a helmet? It’s not to be found in any statute ( I have read EVERY NJ statute regarding motorcycle helmets) and I’ve spent a lot of time searching for what the chief administrator specifically says. I can’t see getting a ticket based on what’s written in a manual. On that note, if I couldn’t get a ticket for the reflectorized tape, then the other mentions in the manual shouldn’t be binding either (unless there is some official requirements by the chief administrator, but following the law and not what’s in manuals shouldn’t be so difficult).
