Older drivers recognise their declining level of competence generally and drive less distance and at less busy times.
There are less studies for crash rate vs distance travelled but if you look the crash rate vs distance travelled rises as we age.
How ageing affects driving
The number of drivers over the age of 70 has doubled in the last 20 years in Victoria alone, with 533,000 older drivers on the road as of 2019.
According to experts such as University of New South Wales research scientist Kaarin Anstey, this comes with an increase in risk.
"Ageing does affect our skills quite a lot. To be a safe driver, we need to have adequate reaction time, visual function and cognitive function. And these are all things that show decline in normal ageing," Kaarin told Insight.
"South Australian data showed that at age 60 to 69, when a driver is involved in a crash, they are responsible 57 per cent of the time. This rises to 64 per cent in the 70 to 79 year old age group, and up to 85 per cent in the 80 plus age group."
"So, it is really the over 80s where there is a marked increase in risk," Kaarin said.
Each state in Australia has different rules and checks for ageing drivers.
NSW has the strictest laws, requiring drivers to have annual medical assessments after the age of 75, and practical assessments after 85.
Queensland requires a yearly medical check up over the age of 75, with no practical assessments required.
Other states like Victoria and South Australia rely on self-assessment.
Despite the variation in the way the states approach testing, research from the Department of Infrastructure and Regional Development shows that the crash rate for older drivers is consistent across Australia.
But testing does help detect some drivers that should no longer be on the roads.
Kaarin Anstey says that while testing is helpful, some of the tests conducted such as the visual acuity test aren’t shown to be very effective. And that self-assessment is often unreliable.
"We've all been driving for decades. We don't actually know much about our habits until something really bad happens," she said.[/i]
