TL;DR: In this paper, the authors identify whether measures of visual processing ability, including the useful field of view test, are associated with crash involvement by older drivers and find that older drivers with a 40% or greater impairment in the SVM were more likely to incur a crash during 3 years of follow-up, after adjusting for age, sex, race, chronic medical conditions, mental status, and days driven per week.

TL;DR: A model incorporating the effects of distractors and secondary task demands was developed to aid in predicting visual search performance and found a reduction in the size of the field as a function of age.

TL;DR: The identification of a visual attention measure highly predictive of crash problems in the elderly is pointed to a way in which the suitability of licensure in the older adult population could be based on objective, performance-based criteria.

TL;DR: The best predictor of accident frequency as recorded by the state was a model incorporating measures of early visual attention and mental status, which together accounted for 20% of the variance, a much stronger model than in earlier studies.

TL;DR: Results replicated earlier studies showing that many older drivers limit their exposure to driving situations which are generally believed to be more difficult, and those with the most impairment reported avoiding more types of situations than other less impaired or non-impaired drivers.
