Can 12123 Display Traffic Violations Immediately?

12123 cannot display traffic violations immediately. 12123 is just a platform and does not show violations right after they occur. Traffic violations are determined through electronic monitoring, and the captured behavior needs manual review. The records are usually uploaded within approximately 72 hours, and they can be checked on the 12123 platform within a week at most. There are two ways to handle violations: online processing and processing at the vehicle management office. Online processing has certain limitations, such as being applicable only to violations with fines not exceeding 200 yuan, violations where the penalty points do not reach 12 after deduction, and non-on-site enforcement violations. Processing at the vehicle management office is a more reliable method. Nowadays, many vehicle management offices have self-service terminals for handling violations, with staff available to guide users. Handling minor violations can usually be completed in just two to three minutes.
