I was walking home from school with a friend. (I'm in middle school.) We were going through the high school parking lot, and a van came speeding straight at as. I only got one number from the license plate. I however, can identify the vehicle, and the high schoolers have to park in the same spot every day, and I know where he came from. I also saw the driver, but does it matter if I didn't see the plate? Would I go to the police, or go to the school and speak to somewhere there?
