Each of 3 volunteers were exposed to 0, 950, or 1900 ppm CO via mouthpiece at intervals designed to produce COHb of <2, 8 to 12, or 17 to 23%. Actual levels, as determined by respired air measurements, were 0.00 to 0.69, 6.30 to 13.81, and 15.10 to 2l.87% COHb, respectively, for the 4 to 6 hr of tests. Volunteers were then subjected to a series of sensory performance, normal driving, and structured psychomotor driving performance tasks. Data from the 3 were normalized and pooled. Performance decrement in several tasks, including velocity, headway, gas pedal reversal, and deflection was observed with increasing COHb. Increased response time to sensory detection of relative velocity and taillight brightness was observed.
