A three-car crash has been blamed on a bad fitting Ugg boot, police say.

Acting Senior Sergeant Simon Reay, of Dunedin, said police were called to Corstorphine Rd, at around 5pm on Monday after a car crashed into two parked vehicles.

The 64-year-old driver was travelling down the road at speed when his Ugg boot slipped off and got wedged under his brake and over the accelerator.

He sped straight through a give way sign, ramming straight into a garage, crashing into two parked cars.

Emergency services arrived and he was taken to Dunedin Hospital as a precaution, Snr Sgt Reay said.

Inquiries were ongoing and a blood sample was taken to test for the presence of alcohol.
