Patrick Street was brought to a standstill after emergency services rushed to a car which had rolled and landed on its roof on Wednesday afternoon.
A female driver, 64, crashed into a parked car on Patrick Street, between Market Lane and Sloane Street.
Stawell Acting Sergeant Bryan Anderson said the cause was being investigated, but could have been a medical issue.
“The cause of the crash is still yet to be determined, the matter will be finalised on Friday or Saturday, but it could have been the result of a medical issue,” he said.
The driver, a Stawell resident, left the scene unscathed.
Acting Sergeant Bryan Anderson said the incident was a reminder to other motorists about assessing health and awareness before getting behind the wheel.
“It is important to manage your own fatigue, rest if you feel tired and yourself and other road users will benefit,” he said.
State Emergency Service duty officer for Stawell Jenny Rooke said they arrived at the scene and spotted a car on it’s roof and prepared to rescue anyone trapped inside.
“Luckily there was no one trapped, the driver was fine, no major injuries and that is the main thing,” she said.
“We got there and assessed what was going on and helped clean up the scene.”
Ms Rooke also said Stawell SES had only just returned from a call-out at the Grampians when they received a call to respond to the car crash on Patrick Street.
“Members had only just got back from a carryout at Chautauqua Peak in the Grampians, they were refueling their truck when the guys got the call at the petrol station to go out to Patrick Street,” she said.
“We just want to encourage drivers to stay alert at all times, especially in rural communities where many drivers may be traveling long distances.”
A resident near the scene, who wished to remain anonymous, said they heard a loud bang and immediately rushed outside.
“I just don’t know how it would have happened, she seems to have hit another car and pushed it on the nature strip and her car has rolled,” they said.
“The driver crawled out and was in shock, she was apologising profusely.”
