1. Bring your ID card, driver's license and driving license to the illegal handling hall;

2. Pay a fine at the designated bank with a penalty decision;

3. Once the penalty decision is printed, the penalty must be paid within 15 days. If it exceeds 15 days, a late payment fee of 3% will be added every day, but the total amount of late payment fee cannot exceed the total amount of fine;

4. Pay the fine, keep the bill, and check the illegal information online in a few days. If the illegal information is gone, the bill can be kept, but if there is illegal information on the internet, then take the payment slip to the legal department of the traffic police force to explain the situation. After confirmation, the staff will directly delete the illegal information of the parties.
