A speeding teenager performed a handbrake turn, lost control of his car and hit a lamppost.
Vadims Hmirovs, 19, was fined and banned from the road after admitting driving dangerously on July 7 on York Street, Aberdeen.
He also admitted driving without insurance.
The teen further admitted driving with 82 microgrammes (mcg) of alcohol in 100ml of breath in a separate incident on Kerloch Place, Aberdeen, on June 27. The legal limit is 22mcg.
Fiscal depute Kelly Mitchell said a witness saw Hmirovs’ vehicle coming from the Beach Boulevard “at speed” at 6.40am before skidding and hitting a lamppost.
She added the other incident happened at around 4.45am and that police had attended for an unrelated matter.
Defence agent John Ferrie said his client had no previous convictions.
He added: “These matters happened in fairly close proximity to each other in terms of time.
“For some reason he doesn’t know why he acted in the manner libelled.”
Sheriff Philip Mann told Hmirovs, of Middlefield Place, Aberdeen: “This was an inexplicable period in your life.
“Why you chose to drive in this manner I don’t know. Possibly you were showing off to friends or just acting the fool.”
He fined him a total of £900 and disqualified him from driving for 14 months.
