This petition was rejected

The Government e-Petitions Team gave the following reason:

We can't accept your petition because the UK Government and Parliament aren't responsible for the issue you raise. Traffic enforcement, including parking, is a matter for local authorities

You could raise your issue with a local councillor who represents you. You can use this page to find out who your local councillors are, and how to contact them:
