Discription of Events: During my commute from Westfield, PA to Corning, NY, this car was speeding and passed me and several other cars in no passing zones when it was not safe to do so. After I stopped to get gas in Elkland, PA, this car pulled out behind me once again and did the same thing. There is currently road work going on and this car attempted to speed through those zones or drive around cars stopped by the flagger. This car cut off several other drivers as it weaved and sped through traffic.
