Hello dear ~ I'm glad to answer this question for you. 12 123 abnormal service C 1005 1 The reasons are as follows: the abnormal service of traffic control service c 100002 is due to problems in the local computer room, or the abnormal service is caused by multiple people logging in at the same time. If the business to be handled is urgent, you can call the voice service function of 12 123 for consultation. If the voice service function of 12 123 is not available in your area, you can also call 122 for consultation. Because the voice platform is the communication between people, it can better absorb and adopt the opinions and suggestions of the masses, and at the same time, it can effectively and quickly answer the doubts about related business and policy handling. The opening of voice service function has narrowed the distance with the masses and provided them with more quality and temperature traffic management services. If it is really not possible, you can go to the traffic law enforcement station of the municipal vehicle management office for on-site handling.
