Florida began statewide Inspections apparantly, in 1969 and continued until 1982 where they discontinued them altogether. However different cities and counties in Florida had inspections as far back as 1946 that we are aware of. Car dealers and roadside checks used a system to show a car was in safe condition.
This 1958 Florida Inspection sticker was created from a similar Florida sticker.
It has a patented "Peel and Stick" adhesive format to adhere to the inside windshield.
It can also be ordered with your license plate number in place of the serial number for $10.00
