How are the 3 chances of traffic restriction in Shenzhen calculated?

[Orlando]

Shenzhen traffic restriction 3 chances: For the first 2 violations of traffic restriction rules by a vehicle, no penalty will be imposed. Starting from the 3rd violation of the traffic ban, a fine will be issued with 3 demerit points deducted. If a vehicle is recorded driving on multiple restricted roads during the restricted hours on the same workday, it will only be counted as one driving record. The first and second violations of traffic restrictions will not be penalized, with penalties starting from the third violation according to law. Shenzhen's traffic restriction cameras capture violations every 4 hours in a day, and cross-region ban violations are processed separately. To avoid penalties, vehicles should be parked in residential or company parking lots during restricted hours, or a Shenzhen traffic permit can be obtained.
