In what year did the requirement for retractable seat belts start?

The requirement for retractable seat belts in vehicles began in 1980. This marked a significant step in automotive safety regulations, aiming to enhance passenger safety by ensuring that seat belts are more user-friendly and effective in preventing injuries during accidents.

Retractable seat belts allow for easier use by automatically retracting when not in use, encouraging occupants to fasten their seat belts without struggling with loose straps. This change in regulation reflected a growing awareness of the importance of wearing seat belts and contributed to overall improvements in passenger safety standards.

The other years listed did not coincide with the initiation of this requirement, as earlier regulations focused on standard lap belts and other safety features without mandating the use of retractable mechanisms. The choice of 1980 highlights a key moment in the evolution of vehicle safety regulations that are still in effect today.
