Of course, NC legislators have presented us with a statute which is vague. According to case law, State of Washington v Maxwell, a reasonable person of average intelligence has no clue what FMVSS 218 is, does not even know where to find FMVSS 218, and the statute does not help point them to it. Even if they are diligent or lucky enough to locate it, it is not written for them to be able to use it and conduct testing. That's just the beginning of how it is vague. For you people who want to seriously get into this, please begin researching through the collection of links to case law documents at http://boltusa.org/?q=node/7

For those just beginning to research this statute,, please begin by contacting your state legislative rep. You can find them through http://ncleg.net and you can either email them or call them. Ask the following question:
How can I ensure, with absolute certainty, compliance with General Statute 20-140.4(a)(2) and FMVSS 218? Is FMVSS 218 something that I can ensure compliance with?
They do not know and will most likely give you bad information, such as pointing you to test results for only 40 helmets tested in the previous year. This is incorrect. The correct answers to both questions are simple; you cannot. If, despite due diligence, such as contacting your state legislature, you cannot ensure compliance with a law, then that law lacks due process and is unconstitutional, in violation of Amendment 14 of the US Constitution.

Please beware of incorrect information being distributed by the NC State Highway Patrol. They have been telling many untruths, such as telling people there needs to be an inch of foam, or saying what the helmet needs to be made of. Neither the state nor federal laws have any such specifications.
