Basic to the issue of driving competence, especially for older drivers, is the need to balance mobility and autonomy with personal and public safety. Role of Driving Simulators. Driving assessment tools and training methods are aimed at not only identifying at-risk older drivers, but developing effective methods to enhance driving competencies. Methods used to assess driving ability are discussed, including on-road driving tests, simulated driving tests, and batteries which evaluate driving-related skills. Promising methods to extend the safe mobility of older drivers are reviewed, including driving simulation training and training programs designed to sustain the skills needed for safe driving (e.g., cognitive training). Key Results of Driving Simulator Studies. Studies on driving simulator training suggest that such training may improve not only overall fitness to drive, but also specific skills such as visual scanning ability and right foot coordination. Limitations and Future Research. Conclusions are made regarding the need for standardization of assessment methods, and further investigation of the validity and reliability of on-road evaluations targeted to older drivers. Recommendations for future research are made.
