A drug driver spotted weaving back and forth across a busy dual carriageway claimed a bald tyre was to blame for his erratic driving.
Scott Walker, 44, had more than twice the permitted level of a cocaine derivative in his system more than 24 hours after taking the drug.
Walker, from Cumbernauld, admitted driving on the A9 Stirling to Inverness road with excess Benzoylecgonine in his blood.
He also admitted having no insurance and a tyre that was so bald a portion of the cord was exposed on March 13, last year.
Positive drug swab
Fiscal depute David Currie told Perth Sheriff Court: “At 1.30pm on Sunday police received a call from a concerned member of the police that a vehicle was swerving on the A9 northbound at Greenloaning.
“Shortly after, the police set up a static position at Broxden. They were concerned about the manner of driving and pulled the car over.
“They required the accused to comply with a roadside breath test, which was negative for alcohol, and drug swabs were taken. They were found to be positive.
“Police noted the rear offside tyre was in a state of disrepair and the cord was actually showing. The accused was not covered under his insurance policy for using the vehicle for business.”
Walker, representing himself, said: “I wasn’t affected driving by what I took. It was the Friday night I took it.
“The reason I was swerving about was a gouge out of the tyre. I went to check it when the police pulled me over.”
Sheriff Gillian Wade banned Walker from driving on an interim basis and deferred sentence for the preparation of background reports.
