For citizens, a snow alert means that all vehicles parked on those streets where signage indicates no parking during a snow alert are required, by law, to be moved elsewhere in order to allow snow plowing of the road surface.  Snow alert signage dictates which side of the street residents may not park on when an alert is declared.  Residents may park in their driveways (if available), alternate side of their street or another street not marked.  These parking restrictions are put into place for the purpose of public safety as well as the efficiency of snow clearing on Borough streets; vehicles in violation are subject to ticketing and/or towing by the Lansdale Borough Police Department.
