A member of the public alerted police after sniffing out a drink-driver in a petrol station, a court has heard.

Lisa Ann Williams, formerly of Pembroke, now of Cefn Coed, Sleddau, pleaded guilty to driving while over the legal alcohol limit when she appeared before Haverfordwest magistrates on Tuesday.

The court heard that a member of the public called the police after noticing a smell of intoxicants coming from Williams, 36, while she was in a petrol station on February 16.

Police stopped her Seat Ibiza at 4pm on the A4076 at Sentry Cross, Milford Haven, and she was found to have 49mg of alcohol in 100ml of breath, the legal limit is 35mg.

Vaughan Pritchard-Jones, prosecuting, told the bench that there was no suggestion of bad driving.

Mike Kelleher, defending, said: “Things were not exactly going well for the defendant at that time. She had been made homeless and as a result her family was split up, some in Fishguard and some in Pembroke Dock.”

He added that Williams had drank alcohol while on prescribed medication. She had fallen asleep on the day in question, and thought she would be alright to drive when she woke up.

“She did not think she was over the limit. It was a difficult time for her.”

The court heard that Williams had now found a home, returned to her job, and her family had been reunited.

“Things are looking an awful lot better for her,” Mr Kelleher added.

Magistrates fined Williams £120 and ordered her to pay £85 court costs and a £30 surcharge.

She was banned from driving for 14 months.
