Effects of carbon monoxide intoxication on driving tasks. Paper presented at the 53rd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1974.

Possible effects of CO exposure, as related to carboxy hemoglobin levels of less than 20%, on driving-related performance, are investigated. In particular it was confirmed that COHb levels produced reduced headways, lack of mirror sampling, increased perceptual uncertainty, and reduced visual efficiency.
