Samenvatting
The nighttime driving performance of five healthy young drivers and five healthy and drivers under the influence of carbon monoxide (12% carboxy-hemoglobin (COHb) level) was investigated. The young subjects were significantly affected in their visual search and control behaviour, and in their physiological measures in terms of mean heart rate due to COHb effects. The visual search behaviour of the aged subjects was affected differentially compared to the young at elevated COHb levels.
