A SHONKY attempt at parking in a police station car park alerted Adelaide police to a woman driving more than five times over the legal blood alcohol limit.

Police spotted the woman making a number of unsuccessful attempts to park her car in the public car park of the Sturt Police Station on Sturt Road at Bedford Park about 6pm on Friday.

The 57-year-old woman was breath tested and returned a reading of 0.268 per cent BAC - more than five times over the legal limit.

The Flagstaff Hill woman was reported for drink driving and immediately had her licence suspended for 12 months.

The woman will appear in court at a later date.
