Laura Jones, 40, was driving along Dawley Green Way in Telford with her five-year-old daughter when she lost control of her silver Vauxhall Astra, hitting several trees before it landed on its roof.
Her daughter was pulled free from the car by a passing motorist before emergency services arrived to free Ms Jones, who was unconscious.
The operations manager, from Horsehay in Telford, was taken to Royal Stoke University Hospital but medics could not save her and her life support was switched off on September 25 last year, three days after the crash.
At her inquest at Shirehall, coroner’s officer Michael Caesar Homden said that a pathologist’s report showed there were no drugs or alcohol in her system.
Based on witness statements and condition assessments of her car and the road, collisions investigator PC Robert Seager said the likelihood was that she suffered a “medical episode while driving”.
One witness described seeing Ms Jones’ car veer off to the left of the road for no apparent reason. He helped pull her daughter free from the car.
John Ellery, coroner for Shropshire, Telford and Wrekin, accepted PC Seager’s assessment.
He recorded a conclusion that she died in a road traffic collision, saying: “There is no other reasonable explanation.”
