Maryland family's SUV bursts into flames while they slept, video shows: 'We were terrified'

The sound of exploding airbags awoke a family of five recently as an SUV burned in the driveway of their Maryland home. 

Vicki and Philip Hill, who have 5-year-old twins and a 7-year-old, told FOX 5 that if their SUV had been parked in their garage when it suddenly caught fire, it could have caused the house to explode because it’s right next to the gas line. 

Video from the home's doorbell camera shows the vehicle start to smoke before 6 a.m. on May 14, before it burst into flames.
