The present study compared the driving behaviour of older (67+) drivers who either drove throughout the year or only during the summer season. 41 older subjects drove in VTI’s simulator in both winter and summer conditions, partly combining the driving task with a secondary task of visual detection. It was hypothesised that the groups would differ as to their driving behaviour and that any differences would be more pronounced during winter conditions. While the groups did differ with respect to stress experienced in traffic (more for those driving in summer only) and to cognitive status (only in males, lower for those driving in summer only), there were practically no differences in their driving behaviour. The conclusion is that the strategic limitation of driving exposure either had not affected their driving behaviour or that the differences were too subtle to be detected in a simulated driving situation.
