What does a white circle on a 2016 inspection sticker mean?

A white circle on a 2016 inspection sticker typically indicates that the vehicle has passed its safety inspection but not its emissions inspection, depending on the state regulations. This designation helps differentiate between vehicles that are compliant with all inspection requirements and those that still need to address emissions issues. It serves as a visual cue for law enforcement and inspection officials. Always check local regulations for specific meanings, as they can vary by state.
