How much is the limit in Beichen District of Tianjin today?

Under normal circumstances, from Monday to Friday from 7:00- 19:00, within the outer ring road, the car number of this city is restricted ("one day less every week"); Outside cars are not allowed to enter the area within the outer ring at 7:00-9:00, 17:00- 19:00, except when driving according to the tail number.

In case of foggy weather, the third-level response is limited by the tail number all day; First-and second-level responses, the single and double numbers in the area under the jurisdiction of Tianjin are restricted ("one day less every two days").

Tail number restriction is a policy adopted before the Beijing Olympic Games, aiming at smooth traffic and meeting air quality standards. Now it has become a long-term policy. One is to reduce the traffic burden caused by the rapid growth of vehicles in Beijing, and the other is to reduce the exhaust emissions of motor vehicles in Beijing and control the air pollution index in Beijing within a reasonable range.
