THE man who narrowly avoided serious injury in a traumatic road incident yesterday morning has spoken out about the harrowing experience.

Matty Brunker was travelling on the Peak Downs Highway with a co-worker just before 5am yesterday when tragedy stuck.

His co-worker, a 25-year-old man, was seriously injured when a B-double collided with their parked ute between Nebo and Coppabella.

A RACQ CQ helicopter crew, including a Critical Care Paramedic, worked to treat the man at the scene for almost two hours before he was flown to Townsville hospital in a critical condition.

A spokeswoman for the rescue chopper said the 25-year-old man suffered suspected brain and spine injuries.

Taking to social media, Mr Brunker said he was lucky to escape the crash with just "a few grazes".

He said the pair were about 30km away from their destination when they pulled into a designated parking area for a toilet stop.

"(We were) just standing next to our vehicle about to head off when I looked up and (saw) a B-double flying towards us at full speed out of the darkness," he said.

"Within a split second the truck had collided with our vehicle and completely smashed it and then flew off the road into the scrub.

"I was lucky to just have my pants ripped and cop a few grazes but unfortunately my bro was not as lucky and was flung through the air from the impact.

"I'm praying he's gonna be OK."

A Townsville University Hospital spokeswoman said the 25-year-old man's condition had stabilised overnight.

In a post shared more than 900 times on Facebook, Mr Brunker said he and his family were "thanking God" he was still here.

"Cherish every day folks cause you never know when your number's gonna be up," he said.
