I was stopped 3 months ago using phone but my licence was away getting renewed so could not produce it and was told by police officer I would receive a summons he did not give me a ticket or any paperwork.
I have now moved house but have arranged for Royal Mail to redirect my post and have changed my address with the licensing authority. Is there anything else I should do?
Tell the police station where you were asked to produce that you have moved. Otherwise you could have a summons issued without your knowledge and end up with a fine being issued and then a warrant for non payment of that fine.
Check with your local magistrates court to see if anything has been issued to date.
