Abstract This Short Communication looks at carbon dioxide levels in an estate car. It consisted of a series of experiments involving: two adults and two children; two adults; and only a driver. Measurements were taken during a journey between two towns both while ventilation was on giving light forced air inflow, but the car’s interior air circulation off, and while both ventilation and air circulation were operating. In the case of the family of four with the interior air circulation on, the concentration of carbon dioxide was 3018ppm after 25min of driving. When there were two people in the vehicle, after 45min this changed 4844ppm. Finally, it reached 3576ppm after 60min with only the driver. The experiments were stopped if there was an observable decline in the driver’s concentration; after the car’s air circulation had been switched off, the symptoms disappeared within 5min.
