A TEENAGER was involved in a crash after he got behind the wheel with a cocktail of drugs in his system.

Joshua Mackay, aged 19, admitted three drug-driving offences and driving otherwise than in accordance with a licence when he appeared at Weymouth Magistrates Court.

The court heard Mackay had been subject to a roadside drink and drug test after he had been involved in a crash on Sandford Orcas Road, near Sherborne on September 29, last year.

Richard Oakley, prosecuting, said Mackay, of Mulberry Gardens, Sherborne, tested negative for alcohol but a Drugwipe test came back positive and the teenager was arrested.

Mr Oakley said Mackay admitted to officers he had used cannabis prior to getting in the car that evening.

He was taken to the police station and a blood sample was taken.

Mackay was found to have no less than 14 microgrammes of cocaine, 2.8 microgrammes of delta-9-tetrahydrocannabinol (the psychoactive ingredient in cannabis) and 120 microgrammes of Benzoylecgonine (a by-product of cocaine use) per litre of blood.

The legal limits are 10 microgrammes, two microgrammes and 50 microgrammes respectively.

The defendant, who was the registered keeper of the vehicle but only held a provisional licence.

He was driving unsupervised at the time of the crash.

Provisional drivers must be accompanied by someone aged over 21 who has held a full driving licence for at least three years.

Details of the circumstances surrounding the crash were not given to the court.

Mackay, who appeared unrepresented, told magistrates he admitted to what he had done and now wanted to "move on and start over again."

"I have got rid of all those people in my life who have led me on this road," Mackay said.

He added he had now got a job in a warehouse and wanted to turn his life around.

Chairman of the bench John Young said the incident had been a "moment of madness" but an accident had been "inevitable" when he decided to get behind the wheel unsupervised and with drugs in his system.

Mackay was fined £175 and disqualified from driving for 12 months.
