Rider critical, man charged after SA crash

A motorcyclist has been critically injured in a collision with an alleged drink-driver in Adelaide.

Police say the driver performed a burnout in his Holden sedan in a service station at Seaview Downs on Saturday afternoon before colliding with the motorcycle on the road.

The rider was taken to the Flinders Medical Centre in a critical but stable condition.

The driver, a Dover Gardens man, 62, was breath-tested at the scene.

Police allege he returned a reading of .178, more than three-and-a-half times the legal limit.

He has been charged with aggravated driving without due care, drink driving and causing injury by dangerous driving.

It's expected he will be bailed to appear in the Adelaide Magistrates Court at a later date.
