A young driver was more than four times over the legal alcohol limit and was drug-driving when he crashed his car near Creswick last year.
Jesse Jelly, 24, said he could not remember the days leading up to the August 6 crash or the month after it.
He pleaded guilty at the Ballarat Magistrates Court on Friday to three charges, including drink-driving, drug-driving and careless driving.
The court was told Jelly was driving north along Bungaree-Creswick Road, Wattle
Flat, when he lost control near Howards Road at 6.25am.
Police prosecutor Leading Senior Constable Clint Prebble said the car came to a stop near a paddock fence line.
He said a witness saw Jelly with his head on the steering wheel and appeared dazed.
Leading Senior Constable Prebble said the witness phoned triple-zero and an ambulance took Jelly to Ballarat Health Services with a head injury.
He said a blood sample showed the P-plate driver had a blood alcohol reading of 0.212, while an oral fluid test contained methamphetamine.
Representing himself, Jelly told the court there was nothing to take into account in the plea hearing.
He said he did go to bed after drinking the night before and got up and drove.
Jelly said he received cuts and bruises, and his car was written-off.
He said he lost his job as a tyre fitter last Thursday.
After viewing photos of the crash, magistrate Ron Saines told Jelly it was a serious crash that could have killed him or someone else.
"This is such a serious matter," Mr Saines said.
Jelly is being assessed for a community corrections order and is due to be sentenced on Friday afternoon.
