The mandate for auto insurance was signed into law by the governor of each state, acting on legislation passed by the state legislature, and in the federal context, it was signed by the President after Congress approved the Motor Vehicle Safety Act. These signatories gave legal force to the requirement that drivers carry liability coverage before operating a vehicle.

State-Level Authority
Each state's legislature drafts and passes auto‑insurance statutes, which are then presented to the governor. The governor's signature enacts the law, making insurance mandatory for drivers within that jurisdiction.
Federal Involvement
While the primary enforcement is at the state level, the federal government set baseline standards through the Motor Vehicle Safety Act of 1966. President Lyndon B. Johnson signed this act, establishing nationwide safety and insurance frameworks that states built upon.
Impact on Drivers and Insurers
Once signed, the mandate requires all licensed drivers to maintain minimum liability coverage, influencing policy pricing, underwriting standards, and compliance monitoring by state departments of motor vehicles.
