My 2016 T & C was parked on an incline when about 5 minutes after I exited the vehicle, it began to roll backwards. Van was in park and off. It rolled back and hit a church sign which stopped it from going over a steep bank and into traffic on Route 29 near Gretna, Va. Extensive damage to sign as well as probably total loss of my van.
