The driver of a vehicle in New Milford was unaware that the rear of the car was on fire until being stopped by another motorist.  Water Witch Hose firefighters responded to Candlewood Lake Road shortly after 4pm on Friday and found that the Good Samaritan was able to help the family of four out of the vehicle before the fire reached the passenger compartment. Firefighters quickly extinguished the blaze and prevented leaking fluids from reaching the storm drains.
