Mistake.

Before I start this topic and people judge this is the first time I've ever be remotely trouble.

The girlfriend got a new car at the start November, on the way home from picking it up I decided on a quiet road in a non residential area to drive it. Little did I know the police were parked up and watched us swapping seats. I drove less that 2 mile up the road and at the turn chance I pulled in and swapped over again. The police were tailing us, which I didn't know. By the time we swapped over he police had just pulled up. They suspected drink driving at the start. The police officer said he should be giving a fixed noticed and this was an 'absolute crime' but he just cautioned us and said he's referring it to the prosecution office. His words was 'il write my report in your favour, the officer might throw it out or could make an example'. I have my own insurance but due to only being 23 I am not covered on anyone else's car, I been driving 6 years with no previous offences. Basically does anyone know what could happen or when il hear word? It's been over 4 months. Thanks Niall
