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?Janet R
