Alarming data reveals a massive discrepancy in driving behaviour across Australia.

The state with the highest likelihood of being involved in a car accident left drivers with a one-in-five chance of involvement in a motor vehicle accident.

Conducted by insurance comparison site Compare the Market, the survey analysed responses from 1019 participants aged over 18, and discovered that 20 per cent of respondents from within Victoria (below, Melbourne) said they had been involved in a car accident within the last 12 months.

At the opposite end of the scale, Western Australia reported the lowest car accident risk, with just 7 per cent of participants reporting that they had been involved in a car accident within the last year.

New South Wales ranked second-worst at 16 per cent, Queensland reported a 13 per cent rate, and 12 per cent of South Australian residents said they had been affected.

The data did not provide state-by-state analysis for the ACT, NT or Tasmania. Responses for those regions were included in the national average, with 14.9 per cent of Australians reporting being involved in a car accident in the last year.

The data also revealed a close split between those who filed an insurance claim and those who elected to pay for repairs themselves.

Of the 14.9 per cent of respondents who had been involved in an accident, 6.4 per cent filed a claim with their insurer, but 5.9 per cent either paid for their own repairs or lacked coverage. The remaining 2.6 per cent chose not to repair damage sustained.

The data also reinforces traditional and more comprehensive crash data, suggesting that younger and less experienced drivers face a higher crash risk. Rather than breaking this information down by age group, Compare the Data segmented by a less informative split by generation.

Based on this information, 24 per cent of Gen Z drivers, or those aged 18 to 29, reported being involved in an accident; Millennial drivers, typically aged 30 to 45, reported an accident rate of 20 per cent. 11 per cent of Gen X, which typically covers 46 to 61-year-olds, reported an accident in the last year, while Baby Boomers, aged 62 to 80, reported only a 6 per cent rate.
