A man from Northamptonshire, who left two sisters paralysed after his 4x4 smashed into their family car during a road rage chase, is facing prison for dangerous driving.
39-year-old Andrew Nay from Corby crashed into the Vauxhall as he made a right-hand turn across oncoming traffic near Wellingborough - causing sisters Katrina and Karlina Raiba, aged five and eight, to suffer life-changing injuries last October.
He was found guilty of causing injury by dangerous driving at Northampton Crown Court today.
The court heard how he started tailgating and 'bullying" cars in front of him on the A509, causing one driver to overtake another vehicle because they were so scared of his driving.
He then did the same to a Mercedes car.
As the driver of the Mercedes approached a junction and waited to turn right, Nay undertook him and smashed into the car being driven by the father of the two girls.
Moments before the crash, he was seen laughing and smiling with his passenger.
Nay, who was a leading driving instructor for Jaguar Land Rover at the time, pleaded guilty to causing injury by dangerous driving but denied other aggravating factors preceding the crash, including tailgating and aggressive driving.
The family agreed to release dashcam footage which shows the horror of what happened in order to demonstrate the dangers of irresponsible driving.
