This ticket is not a penalty decision or a receipt. At most, it is a fine voucher to record your violations. Traffic police copy cards and take photos, so there will be records. So this ticket does not need to be signed by the punished person. Therefore, you should pay the fine on time in accordance with the relevant provisions of the Traffic Safety Law and the Administrative Punishment Law. After the fine is paid, the record will naturally show that the fine has been paid, and there is no case that the penalty sheet is invalid due to its negligence.
