This paper presents the results of the investigation on a driver model that can be adjusted to perform the role of an impaired driver (especially, an alcohol-affected driver) who exhibits the deterioration in driving skills in correlation with a specific level of impairment. The linear vehicle model providing lateral displacement and yaw is coupled with the driver model that is derived as a linear quadratic regulator with delay. The decrement of performance is modelled by decreasing parameters that are preview time, visual perception, control gains and increasing reaction time. By comparing the standard deviation of the lateral position between the model and the real driver, the performance of the driver model impaired at the blood alcohol concentrations of 0.05%, 0.08% and 0.11% results in deteriorations of 21%, 26% and 30%, respectively. The lateral error is reduced if the vehicle parameters are adjusted to adapt to the impaired driver model.
