History

Historical Context

1994 marked a surge in U.S. safety regulation, highlighted by the September 13 Federal Assault Weapons Ban and the Violence Against Women Act, showing federal willingness to intervene in public risk. That regulatory climate set a precedent for later large-scale vehicle recalls, such as NHTSA’s current investigation of GM trucks. The Northridge earthquake that year killed 57 people.
