Sutherland was driving his Ford Mondeo at a minimum of 44mph in a 40mph zone around the time of the incident on the Condorrat ring road.
But the trial heard he was likely to have been going faster when he started braking.
Sutherland, of Cumbernauld, was spotted walking away from the crash, saying he needed time to clear his head.
When a passing police officer caught up with him, he swore and blamed Margaret Allan for the collision.
He also claimed his car was being driven by a Romanian man who had taken it for a test drive.
An investigation later found that the anti-lock brakes on Sutherland’s 12-year-old car were not working properly and the battery was not adequately secured.
Judge Tom Hughes told Sutherland: “When asked to identify who was the driver of the vehicle, what was your position on that? You came up with a cock and bull story as well you knew.
“You took no responsibility whatsoever.
“Taking account of the whole circumstances, custody is the only appropriate sentence.”
