Now she has spoken out to thank those who risked their own lives to save her and her nine-week-old Chihuahua.

The last thing Ms Robertson remembers was driving along the Burrendong Way before she careened off a bridge, hit a tree before the car came to a crashing halt on its side.

"The next thing I remember was being in the car trying to undo my seat belt and panicking because I couldn't find my little puppy," she said.

"I got out of my seatbelt and dropped to the passenger window. My daughter said I rang her and told her I'd been in a crash but that the phone cut out. I tried to ring her back to tell her the car was on fire."

For 15 minutes Ms Robertson was trapped in the burning car before strangers heard her cries for help.

"First it was only little orange sparks under the bonnet and then it started to fill up with grey smoke and it got worse," she said.

"I saw someone in a black singlet and another with purple hair and they were punching the window trying to get to where I was.

"They just kept punching and kicking the window until they broke through the back and they got me out that way. I couldn't even see the back seat. It was so petrifying."

Her mind was racing the whole time. About what would happen if those people did not hear her, or if they weren't able to break into the car.

"All I could think was I didn't want to get out of the car until I found my dog, and then I kept picturing my grandkids and what they would think if I wasn't here anymore," she added.

"I can't believe me and my puppy got out alive. I found her under the dash where the fire was. I feel so lucky to still be here. I don't even know how the people heard me."

Pulled to safety, the ordeal wasn't over for Ms Robertson just yet.

"They got me out of the car and got me up the hill and then it made a bang noise," she said about the car which was now fully engulfed in flames.

"I remember screaming when I heard the bangs."

But despite all of this, she survived and managed to walk away relatively unscathed, something she will be forever thankful for.

"No words can describe how grateful I am for them saving my life," she said.

"If they didn't help me I would've been gone. My grandkids would've lost their grandmother, my son and daughter would have lost a mother.

"They told me they were from Dubbo. I only got three names. One guy named Tye from Stuart Town helped and the other fella was Jason Atkins and Michaela from Dubbo."

With no guard rail along the side of the road near Mullion Creek, Ms Robertson would like to see the proper authorities construct one so that something like this can be prevented in the future.
