A pregnant woman and her partner narrowly escaped their smoking car before it burst into flames.
The Pahiatua couple had been on their way to work in Masterton on Monday morning when they heard a "pop" from underneath the bonnet.
"Next minute, she's in full flames," the man said.
"We had enough time to get out, that was it."
The couple, who did not want to be named, had pulled over on State Highway 2 near Mt Bruce after 6am when they heard the noise and saw smoke rise from the bonnet.
The woman, who is almost six months' pregnant, said she believed if they had taken any longer to get out of the burning vehicle, they would have died.
"It was really scary because when we pulled over, we only had two seconds to get out," she said.
"The whole interior was just blacked out with smoke. I couldn't believe how fast it came through.
"If we didn't get out when we did, we wouldn't have survived. There's no way.
"We'd be dead before the fire hit us."
A New Zealand Post truck pulled over behind them to assist.
"The Post truck stopped behind us and we asked if he had a fire extinguisher and he searched but someone had taken it out," the man said.
"By then, it was too late though. [The fire] went up that fast."
The couple had to wait for the Masterton Fire Service to arrive to put out the blaze. One fire engine was sent out, and was at the scene for about half an hour.
Masterton fire station officer Garry Nielsen said a mechanical malfunction caused the car to catch fire.
The mechanical failure had created an oil slick on the road before the vehicle pulled over, so roading contractors Fulton Hogan were called to clean up the road, he said.
The couple had bought the Opel Vectra station wagon on the weekend in a private sale and had not yet insured it.
"We have another car at home, but it's a convertible that leaks," the woman said.
"Because it was raining, we thought [the station wagon] would be the best option, but um, I'd rather get wet."
She said from now on she would carry a fire extinguisher in the car, "just in case".
