Whether the driver was identified or the violation was caught by an unmanned camera determines fine vs. penalty status, so check that line on the notice first.
Most people open a traffic violation notice and check the amount first, but fines and penalties actually differ in who they're charged to, whether the driver was identified, whether license points apply, and what happens next. Whether an officer identified the driver on the spot or an unmanned camera caught the violation alone changes everything about how you should respond.
This list won't resolve any specific case for you. Use it to figure out which line on your notice to read first and which agency's procedure applies, then confirm the details yourself through Traffic Civil Complaint 24 (κ΅ν΅λ―Όμ24) or the issuing agency's own portal, using your actual case record.
