A mum-of-four convicted of a driving offence says she only ploughed into oncoming traffic on the A361 when her driver assist technology "took over" the wheel.
Diane Bryan, 58, got a brand new Toyota RAV4 Excel through the motability scheme just six months before she was involved in a smash near Shepton Mallet.
The motability vehicle scheme allows people who receive mobility personal independence payments (PIP) to trade their payments in for an adapted vehicle.
She insists when she tried to turn left round a bend the wheel refused to budge and then 'white line' technology didn't kick in to pull her back when she crossed the central point.
Dashcam footage shows the car veering over to the other side of the road, colliding with two oncoming vehicles.
The drivers of the two oncoming cars walked away from the scene uninjured.
She was found guilty of driving without due care and attention in court, was given six points and an £800 fine. Diane says the car was scrapped before it was tested.
The Toyota RAV4 includes features such as a Pre-Collision System designed to mitigate collisions by activating the brakes if the driver fails to.
Other features include Lane Trace Assist which keeps the car in the centre of the lane using steering assist and an emergency call system to activate automatically in the event of an accident.
Speaking after the case, Cambridge Weight Plan consultant Diane, from Barnsley, South Yorkshire, said: “I’m a criminal for the first time in my life.
“I went to court and three magistrates totally disbelieved what my husband and I said - I got charged with driving without due care and attention.
"I was offered a Safe & Considerate Driving Course instead of points and a fine which I accepted, but they couldn't provide an adapted vehicle.
"Because I not longer had my vehicle I couldn't do it - but had I been able-bodied, I could have done the course.
“Instead I was given six points on my license for the first time in over 30 years of driving.”
Diane and husband Stan Bryan, 56, were driving from Southampton to Glastonbury on December 17 2022 when the accident happened.
Diane alleges the car was taken away by police but was mistakenly scrapped before it was inspected.
But at Barnsley Magistrates Court on 22 February, she was charged with driving without due care and attention.
After a one day trial she was found guilty and sentenced.
Toyota were approached for comment but say because they were unable to examine the car they could not provide a comment at this time.
A spokesperson for Avon & Somerset Police said: "A vehicle was collected by a recovery company following a three-vehicle collision on Sunday, December 17, 2022, on the A361 in Dean, Shepton Mallet.
"Thankfully, no-one was seriously injured in the collision.
"As this was a low-level road traffic collision, a vehicle would not be recovered for examination under the Police and Criminal Evidence Act.
"The company was contacted two days later by the driver on 19 December who asked where the vehicle was so she could inform her insurance company.
"On 29 December, the vehicle was collected by an individual acting on behalf of the insurance company, as is standard procedure.
"The driver was spoken to under caution by officers where, when asked, she was noted no recent issues with her vehicle.
"She did not mention any defects through the course of the interview.
"The individual has now been found guilty of driving without due care and attention and would have had an opportunity for this to be raised as part of their defence."
