History

Historical Context

After Congress enacted the 1966 Highway Safety Act—prompted by a six-fold rise in traffic deaths since 1925—the National Highway Traffic Safety Administration began applying cost-benefit analysis to safety mandates such as headlamp use. President Gerald Ford signed the 1975 Federal-Aid Highway Amendments expanding federal authority, and Minnesota’s 2024 precipitation-headlight rule on I-94 and I-90 follows that precedent.
