Legal analysis: the ticket issued by the traffic police is invalid without the signature and seal of the traffic police. If it is entered into the system, you can file an administrative reconsideration and decide whether to pay the fine according to the result of the administrative reconsideration. But usually, if there is enough evidence to prove that the ticket is issued illegally, it will still be punished.

Legal basis: Article 109 of the Road Traffic Safety Law of the People's Republic of China, if a party fails to perform the decision on administrative punishment within the time limit, the administrative organ that made the decision on administrative punishment may take the following measures: 1 If the party fails to pay the fine within the time limit, it shall be fined at 3% of the fine amount every day; 2. Apply to the people's court for compulsory execution.
