Bonita Noviello leans into a vehicle to check on her two young granddaughters after passersby helped get the trio out of a burning car on Interstate 93 in Manchester on Saturday.

MANCHESTER — Relatives of a woman who escaped a burning car before it was engulfed in flames Saturday expressed their gratitude to passers-by that helped her and her two young granddaughters get out of the vehicle.

The woman was driving on Interstate 293 Saturday when she ran over a mattress that had fallen from another vehicle. She continued onto I-93 south when she noticed smoke coming from the car and pulled over.

“She was able to get (the two children) out of the car and bystanders came over to assist,” District Fire Chief Mike Gamache said.

Alex Noviello of Peabody, Mass., said in a Facebook post that the woman, Bonita Noviello, was his mother and was driving with his baby daughter and his 2-year-old niece.

Shortly after the woman and children were safely out of the Toyota Corolla, it was quickly consumed by flames on the shoulder of I-93.

“To the guy who stopped to help my mom, daughter and niece while my mom’s car was engulfed in flames; thank you for getting them safely to her house. Also, thank you to everyone who stopped to offer help. The world is a better place with all of you in it,” Alex Noviello wrote.
