To alleviate your fears,
The worst I can see from what you are telling me is that you have committed the offense of driving without due care and attention. If and as i say, very unlikely, if you are summonsed and you have no previous convictions, you would probably receive a caution and no...
The chances of you being summonsed for this offence are very very very minimal.
In any case the police would have to summonse you within 14 days of the period.
If you dont believe me look at my username, it gives you a clue...
