Changing lanes, missing a car – Criminal ?

Hello everybody, I’ve had a bad luck today. I was on a 4 lane road. 2 for the oncoming traffic and 2 for us. I was first on the left and then changed to the right and missed a vehicle which I had after the change directly behind me with light hooves (he probably had to slow down safely) and naturally excited and noted down my license plate. My question is, what kind of punishment is there for such a mishandling? A damage to property has not arisen.
