Ask the Attorney: Waiting for police report

Atty Haymond,
I was involved in an accident on the highway last week during the snowstorm. The person behind me spun out then broad sided me when I slowed down for an oncoming plow. The police eventually came, but all the witnesses except me and the other driver were gone.
I have already received medical attention but am not sure how long the police will take to do there report and what should I be doing to deal with my bills?
