INDIANAPOLIS (AP) — An Indiana woman who had given birth three days earlier says her instincts kicked in when she stopped along a highway to help save the driver of a tanker truck who was on fire.

The truck loaded with jet fuel later exploded.

Holly McNally, 35, helped two men smother the driver’s flames Thursday and move him away from his overturned truck on Interstate 465.

Officials say the 59-year-old driver remains in critical condition Friday morning.

McNally tells WXIN-TV in Indianapolis that she had just visited her newborn boy at a hospital when she saw the burning truck.
