A one-eyed deaf 82-year-old was caught pulling a trailer at 88mph on one of Scotland's deadliest roads. Maurice Hollyfield told a court he wasn't paying attention because he had his stereo turned up loud so he could hear the music.
He also claimed he thought his car's rev counter was the speedometer.
Hollyfield, whose left eye is made of glass, was clocked by a speed camera on the A9 at Waterloo between Perth and Dunkeld. He should only have been doing 50mph.
A doctor told the court Hollyfield was fit to drive, but Sheriff Fiona Tait said: "His health raises concerns about public safety."
She told Hollyfield he faces a ban when he is sentenced next month.
