when did the wearing of seat belts become a law
Seat belt legislation A primary offense means that a police officer can pull a driver over for the seat belt law violation alone, and secondary offense indicates that one can be punished for a seat belt law violation only if they are already pulled over for another reason. By January 2007 25 states and the District of Columbia had primary seat belt laws, 24 had secondary seat belt laws, and New Hampshire had no laws.[11] In 2009, Public Health Law Research published several evidence briefs summarizing the research assessing the effect of a specific law or policy on public health. One stated, "Safety belt laws work, but there is strong evidence to support that primary enforcement safety belt laws are more effective than secondary enforcement laws in increasing seat belt use and reducing crash injuries."[12]
