Twenty-eight-year-old Phillip Layton, of Steynton, admitted the charge when he appeared at Haverfordwest magistrates court on Tuesday.
Prosecutor Vaughan Pritchard-Jones told the court that the incident occurred at 10.30 pm, on September 3.
“The main witness was in her vehicle getting ready to pick her parents up when she heard some kind of bang.
“She realised there had been some kind of accident and that the car involved had driven off, so she got into her car with her friend and followed the defendant’s vehicle onto the A40 Robeston Wathen road.
“There was something hanging off the defendant’s car, the vehicle eventually stopped and the witness called the police,” he explained.
Mr. Layton was arrested and he gave a reading of 91 microgrammes of alcohol in 100 millilitres of breath at the police station.
“The aggravating factor was that after the accident, he continued to drive the vehicle with damage to it and over the limit,” continued Mr. Pritchard-Jones.
Defence solicitor Mark Layton told magistrates that even though his client was pleading guilty to the charge, the facts were not accepted as outlined.
“In a police interview, the account that my client gave was that he went to the Plas Hyfryd Hotel in Narberth for a wedding with his wife and brother.
“They arranged a taxi, but Mr. Layton’s wife offered to drive, and it was she who was driving at the time of the collision.
“As she was shaken up, Mr. Layton then got into the car and drove off looking for a place to pull in, as his wife was upset,” he continued.
“This will have serious consequences as my client is a mechanic. It was an error of judgement, very much clouded by the alcohol. He panicked and made a rather foolish decision,” added Mr. Layton.
Magistrates disqualified the defendant from driving for 24 months and fined him £533 for the offence.
Mr. Layton was also ordered to pay prosecution costs of £85 and a £53 victim surcharge.
