UPDATE: A WARWICK man was in a critical condition in hospital in Brisbane as the Daily News went to print last night, after a horror accident on the highway through town about 11am yesterday.
The 64-year-old suffered a cardiac arrest at the wheel while driving north on Albion St and veered onto a median strip and across the eastern lanes.
His vehicle miraculously missed fuel bowsers in the BP service station forecourt and other vehicles, seconds later crashing through the southern wall of the Beaurepaires workshop on Condamine St.
Shocked tyre-fitter Steve Taylor had momentarily left the shed before the Commodore sedan ploughed through, coming to rest on a huge stack of tyres and shelving inside.
The quick-thinking employee clambered over the debris and wrenched open the driver's door as passers-by called 000.
"He was barely conscious when I got the door open," a shaken Mr Taylor said.
"I was putting lock wings on a tyre and just stepped out and in she comes.
"It's amazing no-one else was hit, I just hope he is OK."
A Queensland Fire and Rescue Service spokesman on the scene told the Daily News there was no fuel spill, "only oil and water".
Tradies were on site yesterday afternoon making repairs to the shed wall.
A spokeswoman for RACQ CareFlight said one of their helicopters flew the man - whose name had not been released last night - from Warwick to the PA Hospital in Brisbane in the afternoon.
She confirmed the patient had experienced a heart attack and his condition was last night listed as "critical but stable."
Driver veers off road after suffering a heart attack
A DRIVER has narrowly missed crashing into petrol bowsers at the Warwick BP Service Station on Albion St after suffering a heart attack behind the wheel, just after 11am today.
The 64 year old Warwick man was travelling north on the highway when he reportedly suffered a heart attack and veered across on to the other side of the road, through the service station forecourt, across Condamine St and into the Beaurepaires workshop.
There were no injuries to anyone else, although a badly-shaken Beaurepaires worker narrowly avoided being struck, having just walked out of the shed.
The worker clambered across a stack of tyres and fallen shelving to get to the Commodore sedan, wrenching open the driver's door to render assistance and describing the driver as "barely" conscious.
Paramedics worked on the man at the scene and he appeared to be conscious and stable when he was transported to Warwick hospital for initial treatment.
He was flown to the Princess Alexandra Hospital in Brisbane by the RACQ CareFlight helicopter around 3.30pm.
He is listed as being in a critical but stable condition.
More to come.
