A police spokeswoman said the 71-year-old driver suffered chest injuries and was admitted to hospital.
Nobody else was injured, she added.
Other drivers described what happened as frightening.
One said: “I had to swerve into the middle lane, I’ve never been so scared in my life.”
Another said: “I honestly thought I was seeing things”, adding that “he must have been doing 80mph easy”.
It is understood the man was arrested before his hospital admission.
