Senior Sergeant Craig Dinnissen, of Dunedin, said the man crashed into the fence of Ross Home & Hospital in North Rd, Northeast Valley, that evening.
He recorded a breath alcohol reading of 1319 micrograms of alcohol per litre of breath, more than five times the legal limit of 250.
Snr Sgt Dinnissen said he had received court summons for both careless driving and driving with excess breath alcohol.
