days
Total to pay (fine + late fee)¥106

Late days counted（from day 16） 2 · Late fee ¥6

How it works

  1. 1Grace period: 15 days from the decision notice
  2. 2Late days = 17 − 15 = 2
  3. 3Late fee = fine × 3% × days = 100 × 0.03 × 2 = ¥6
  4. 4Total = ¥100 + ¥6 = ¥106

Two violation types

On-site violations (ticket issued by police): the 15-day clock starts on the day of the decision. Off-site violations (camera or parking ticket): no late fee accrues before you process the case — the 15-day window starts only when the decision notice is issued after handling.

Under Article 109 of the Road Traffic Safety Law and the Administrative Compulsion Law, the daily late fee is 3% of the fine and is capped at the fine itself, so the maximum total is double the fine. Pay via the 交管 12123 app; unsettled fines may block vehicle inspection and licence services.
