An Adelaide woman has allegedly recorded a "staggering" blood-alcohol level almost seven times the legal limit, police say.
Police pulled over the 36-year-old woman on Wednesday afternoon following a tip-off from a shop attendant who saw the woman get into a car and drive off.
"The 36-year-old woman was subsequently breath-tested and allegedly recorded a staggering blood alcohol reading of 0.336," police said.
