Which organization is associated with the 2-second following interval?

• A. National Safety Council
• B. American Medical Association
• C. National Transportation Safety Board
• D. Department of Transportation

Answer: (A)

Guidelines for maintaining a safe following distance, such as the two-second rule, come from safety organizations that actively promote defensive driving practices. The National Safety Council is a prominent safety advocacy group that publishes and promotes practical driving safety rules, including the two-second rule for keeping a safe gap behind the vehicle in front.

The other organizations have different primary roles: the American Medical Association focuses on medical practice and public health in general, the National Transportation Safety Board investigates transportation accidents rather than standard driving guidelines, and the Department of Transportation sets policies and regulations rather than teaching specific driving habits. That combination makes the two-second following interval most closely associated with the National Safety Council.
