National Safety Council

The National Safety Council (NSC) is a non-profit, Non-Government Organization promoting health and safety in the USA. In 1953, the U.S. Congress and President Dwight D. Eisenhower recognized the importance of the NSC’s efforts with a Congressional charter to: “…arouse and maintain the interest of the people of the United States… in safety and in accident prevention, and to encourage the adoption and institution of safety methods by all persons, corporations, and other organizations.”

Since motor vehicle crashes are the number one cause of unintentional injury deaths in the United States, NSC works with public and private groups to help reduce the number of deaths and injuries on our road.

Concern for the number of rear-end collisions lead NSA to establish the rules to help determine the minimum safe following distance. Through years of research the NSC has established the minimum safe following distance at all speeds in good driving conditions is 3 seconds.
