New footage released by WA Police shows how the quick actions of first responders helped save the lives of an elderly couple who were trapped in a burning vehicle that crashed in the state's South West region.

The couple were driving a vehicle towing a caravan along the South Western Highway in Harvey when they crashed on the morning of March 12.

The accident happened after the driver lost control of the vehicle causing it to fishtail and roll.

The couple was then trapped inside with their seatbelts on as the car caught fire.

Senior constable Kylie James and probationary constable Reece Josemans were among the first to respond to the scene about 10.30am.

"As we just come around a bend, we noticed the vehicle had been crashed and there was a bit of smoke coming from the front of it," Mr Josemans said.

"That's when we went running over."

Mr Josemans and Ms James had seconds to work out a way to get the couple out of the vehicle. 

The vehicle that was on fire had 125 litres of petrol in it and there were two gas bottles on the caravan.

The police officers managed to cut the seatbelts and drag the couple out of the wreckage just before it was engulfed in flames.

"Something that we both talk about today and you know always goes through your head is the fact that the car exploded after," Mr Josemans said.

The elderly couple was immediately taken to hospital with non-life threatening injuries.

Yarloop police officer-in-charge Sergeant Wayne Byram said without the actions of the officers, along with emergency service crews and members of the public who stepped into raise the alarm, the couple would not have made it.

"[It] was incredible," he said.

"On that particular day, everything favoured us and but for that we certainly would have been dealing with a fatal."

South West police superintendent Geoff Stewart congratulated the first officers who responded to the incident, saying their quick actions saved many lives that day.

"I want to mention Reece Josemans and Kylie James from Harvey police station as well as Joe Dainty and Wayne Byram," he said.

"Those four coppers did an amazing, amazing job.

"It was an amazing effort by everyone, particularly, the coppers who put themselves at risk."
