Keiran Morgan, 22, lives nearby and sprinted down to the scene after hearing that his mother Rebecca had been driving alone in one of the cars.
"I ran as fast as I could," said Keiran. "She was in the back of the ambulance and I told her everything would be OK."
West Midlands Ambulance Service sent two ambulances and a paramedic officer to the scene of the crash at 1.01pm.
A spokesman for West Midlands Ambulance Service said: "On arrival we discovered one patient, a woman, who was the driver of one of the cars.
"She was treated for injuries not believed to be serious before being taken to Royal Shrewsbury Hospital for further treatment."

They found nobody trapped and they made the cars safe.
At about 2pm a recovery truck was pulling the car out of the hedge and police were hoping to reopen the road as quickly as possible.
