The older driver's accident risk also tends to increase with increasing age. The high fatality rate amongst older drivers is thought to relate to their increased frailty and consequently a greater risk of crash injuries resulting in fatalities. Factors thought to contribute to the accident involvement of older drivers relate to the physical changes associated with ageing. These physiological changes can affect vision, hearing, physical mobility and cognitive processes. As people age, their ability to process information declines in terms of capacity and speed.
Older drivers are therefore more at risk in novel situations.
The literature on older drivers also cites certain conditions, such as diabetes mellitus or depression and medication use as impacting on driving abilities. Our review found no comparisons with teenage drivers in this regard. The environmental conditions influencing older driver crash involvement include weather conditions and the time of day in which a journey is undertaken. Older drivers tend to avoid inclement conditions and driving during peak times. C. Suggestions for possible future activities Countermeasures Response to a number of countermeasures by older drivers and stakeholders was sought during the study and following is a brief overview of the findings.
