Knife used in road rage incident in SA

An Adelaide man will face court after allegedly using a knife during a road rage incident.

The 22-year-old has been charged with intentionally causing harm after a 47-year-old motorist was cut on his hand on Marion Road, Adelaide, on Monday afternoon.

Police say the confrontation was sparked by the younger man cutting off the other driver and causing a minor collision.

He was refused bail and is expected to appear in Adelaide Magistrates Court on Tuesday.
