SA man caught speeding on methamphetamine

A man has been caught speeding while on methamphetamine in South Australia's southeast.

The 36-year old from Adelaide was fined $926 for driving at more than 150km/h in a 110km zone at Keith on Australia Day, police say.

He was banned from driving for 24 hours and may face drug charges.

Another driver was later caught doing burnouts while more than four times the blood-alcohol limit in Naracoorte, near the SA/Victorian border.

The 46-year-old man lost his licence for a year, had his car impounded for 28 days and will be summoned to appear in court at a later date.
