Update October 2021: According to an article published in Highways, the date for implementing in full, the Part 6 of the Traffic Management Act 2004, is now February 2022.
Finally!

“From December, local authorities will be able to enforce moving traffic offences, such as banned turns, box junctions and driving in formal cycle lanes. They will be expected to use these powers to improve connectivity, boost active travel, and increase air quality by reducing congestion”Baroness Vere, 15/06/2021
Guidance is expected to be published shortly to ensure fairness in using these new powers. School Streets is one way to ensure more equitable streets by protecting children and their families from road danger at the school gate.
