Short story: drove into another car, my fault, other driver injured but not seriously. I was doing about 4mph, dont know about other driver as I didnt see the car before I hit it as I was concentrating on another vehicle at the junction I was using. Have given police a statement, told the truth, etc. Have been told it will be passed for processing and the worst that will happen will be a prosecution for driving without due care and attention.
Does anyone have any experience of this? what happens at magistrate's court? should i get a solicitor? what's the fine/points likely to be? I was totally ok but now I am a bit frightened about the whole legal thing 
TIA
