Three people have died on South Australian roads in almost as many hours this weekend.
A 15-year-old girl died after a Lamborghini driver lost control of the luxury vehicle about 10pm on Saturday night in Glengowrie.
Just an hour earlier, a 76-year-old man from Dublin was killed in a head-on collision between two Holden sedans in Adelaide Plains.
A man and a woman, aged 23 and 20 respectively, went to hospital with serious injuries.
In a separate incident, a 22-year-old motorcyclist died in a two-vehicle crash in Rocky Camp, southeast of the state, just after 6pm.
The state's road toll now stands at 59 compared to 36 at the same time last year.
