The 55 mph speed limit law, which was originally established as part of a national effort to conserve fuel during the energy crisis, remained in effect in many states, including North Carolina, until it was amended. The law was officially repealed on April 2, 1987, allowing states to set their speed limits according to their own regulations and preferences. This change led to an increase in speed limits on various roads throughout the country.

The significance of April 2, 1987, marks the transition away from a uniform national speed limit, reflecting a shift in policy and allowing states greater control over their speed regulations. This historical context is crucial for understanding the evolution of traffic laws, which often respond to changing economic and societal needs.
