Legal analysis: Starting from 7:30 on April 13, 2020, small and micro passenger vehicles with local and foreign license plates carrying less than 9 people (exclusive) are limited to two numbers per day. The week is a cycle, and the week number corresponds to the last digit of the license plate number. The last numbers of the restricted license plates from Monday to Friday are: 1 and 6, 2 and 7, 3 and 8, 4 and 9, 5 and 0. In this way, car owners with vehicle numbers ending in 1 and 6 will not have more restricted days per month than other vehicle numbers. At the same time, they will avoid consecutive restrictions on the 1st and 31st. In addition, they will only be restricted to one day per week, making it easier to remember. At the same time, the number of restricted days per month will also be reduced by 1 to 2 days.

Legal basis: Article 1 of the "Lanzhou Epidemic Prevention and Control Period Motor Vehicle Last Number Restriction Regulations" stipulates that working days other than national statutory holidays (Saturdays and Saturdays that are adjusted to working days due to statutory holidays and holidays) Except Sunday) morning and evening peak hours (7:30-9:00, 17:00-19:30). Article 2 of the "Regulations on Motor Vehicle Last Number Restrictions During the Epidemic Prevention and Control Period in Lanzhou" stipulates that small and micro passenger vehicles with local and foreign license plates can carry less than 9 people (exclusive). Article 3 of the "Lanzhou Epidemic Prevention and Control Period Motor Vehicle Last Number Restriction Regulations" stipulates: There are two numbers per day, and the week is the cycle. The number of weeks corresponds to the last digit of the license plate number. The last numbers of the restricted license plates from Monday to Friday are: 1 and 6, 2 and 7, 3 and 8, 4 and 9, 5 and 0. Motor vehicles with non-Gan A plates are not subject to traffic restrictions on the day they enter Lanzhou for the first time each month. From the next day, traffic restrictions for last-numbered vehicles will apply.
