On May 10, 1966, the Ford Motor Company introduced the first factory-installed three-point seat belts in their 1966 models as part of a significant safety initiative prompted by increasing automobile collisions. While seat belts were known and used, they weren't standard equipment until this pivotal moment. Before this, passenger safety largely depended on the driverβs caution, with no mandated restraint systems in place. The introduction of these belts marked a crucial step towards enhancing road safety, leading to public awareness of car safety features. This move initiated a wave of regulatory changes, compelling other manufacturers to follow suit and resulting in seat belt laws in numerous countries. The evolution of safety standards dramatically reduced fatalities in car accidents and laid the groundwork for the advanced safety features we see today, including airbags and electronic stability control.
