A mother-of-two, who crashed her car following a cereal spillage, was found to have six different drugs in her system.

Miranda Grainne Mayhew, of Freemans View, Merlins Bridge, Haverfordwest, was due to stand trial for driving while unfit through drugs at Haverfordwest magistrates court on Monday, but changed her plea to guilty at the start of the hearing.

Vaughan Pritchard-Jones, prosecuting, told the court that Mayhew, 39, collided with an oncoming vehicle when her VW Golf drifted across the white line in Winch Lane, Haverfordwest, at 4pm on December 18.

The court heard that the crash resulted in minor injuries, and would be covered by insurance.

Mr Pritchard-Jones added: “She appeared to be very pale, dazed, sweating and her eyes kept closing. She had difficulty staying awake.”

Magistrates were told that Mayhew took her eyes off the road when a bowl of cereal tipped over in her car.

A blood test revealed that she had six different breakdowns of drugs in her system, including cocaine, amphetamine and diazepam.

She told officers she had taken the substances three days earlier and thought that they would be out of her system, but police believed she had consumed them more recently.

Mayhew, who represented herself at the hearing, stated that she had been at a friend’s house when an argument began, and left taking her bowl of cereal with her.

She added that the bowl had been in the passenger foot-well and she had not been eating from it while driving.

The court heard that she had a similar previous conviction, and was receiving treatment for drug issues, but the incident happened during a relapse.

Magistrates imposed a 12 week prison sentence, suspended for 12 months, and banned Mayhew from driving for three years.

She was ordered to pay £735 in court costs and a surcharge.
