An Angus man has admitted in court to reckless behaviour which included throwing objects at passing vehicles on a busy dual carriageway.
Gavin Ross could face a jail term after admitting a charge of culpable and reckless conduct at Forfar Sheriff Court.
The court heard Ross had been the victim of a crash as a teenager that resulted in a serious brain injury.
Now aged 35 he was seen just before Christmas standing in the central reservation of the A90 dual carriageway between Dundee and Aberdeen.
Fiscal depute Kirsten Thomson said a driver approaching a junction saw Ross standing with a clear plastic bottle around midday just a few days before Christmas.
He then motioned to throw it at passing cars.
Miss Thomson said: “He then threw it at a passing car, striking the offside of the vehicle.”
Ross was then seen repeatedly stepping in to both carriageways, kicking out at passing traffic.
He then picked up a half brick which he motioned to throw, before launching it at a lorry and striking its offside.
The court heard Ross started walking off again against traffic on the northbound carriageway before police arrived and arrested him.
Ross, 35, of Dalziel Place, Tealing, pleaded guilty to a charge of culpable and reckless conduct committed in December last year.
He admitted throwing various items at moving vehicles, stepping into the roadway and kicking out at vehicles whereby they had to take sudden evasive action causing danger to other road users.
Defence solicitor Nick Markowski said there was a “significant background” to the case - with Ross having been hit by a lorry when he was 18, causing a serious brain injury.
He said: “He committed this offence under the influence of alcohol.
“He has a general anger towards lorries and a passing vehicle was the catalyst for this.”
Sheriff Gregor Murray deferred sentence until next month for social work background reports and warned Ross he faces a potential jail term.
He said: “While I understand and can accept there are medical reasons that may underlay this, you are still in serious trouble.
“At the moment there is clearly only one sentence at the front of my mind.”
