A director used car dealer Dicksons of Perth has been banned from driving for 40 months after being found guilty of causing an accident that left three young children screaming in terror, following a trial last month.

Christopher Dickson (29) was over the legal alcohol limit when he aggressively tailed a family of five through the streets of Perth, The Courier reports.

He eventually cut in front of the car and slammed on his brakes, causing them to run into the back of his Mercedes.

Perth Sheriff Court heard Dickson had then got out of his car to scream abuse at the shaken family.

They locked themselves in their badly damaged car as he hammered on its windows and tried to open its doors before threatening the family with violence.

In the wake of the incident he went to his Perth home.

When police officers arrived a short time later he drank a glass of wine in front of them and claimed his subsequent positive breath test was as a result of alcohol consumed after the accident.

He blamed poor driving on the part of the driver of the other car for the accident and claimed the family’s version of events was greatly exaggerated, accusing the family in court of being liars.

Dickson’s version of events was dismissed by Sheriff Gillian Wade.

In addition to banning Dickson from the road, she fined him £5,000.

Dickson, of Croft Park, Perth, had denied three charges relating to the incident, which took place on February 28, but was found guilty on all counts.

He was convicted firstly of driving on Atholl Street, Kinnoull Street, Marshall Place and Edinburgh Road in Perth with excess alcohol (35 mics). The legal limit is 22 mics.

He was also found guilty of driving without due care and attention by turning right without indicating, moving off from stationary when it was unsafe to do so and causing an oncoming vehicle to take evasive action, overtaking the vehicle before stopping suddenly in front of it and causing a collision with the other car, damaging it.

And he was convicted of behaving in a threatening and abusive manner by shouting, swearing and uttering threats of violence.
