Abstract—Nowadays, driving under the influence of alcohol is an slows simple plex reaction time (2), decreases hand
important factor of the traffic accidents. To study the driver’s steadiness (6), reduces inhibitory control (7), and impairs
brain activities under the alcohol, the event-related brain pursuit rotor tracking (8). Most studies measure the blood
potentials (ERPs) were induced using the traffic environment alcohol concentration (BAC) at the time of impairment and
pictures (human beings, traffic lights, and animals). Generally, BAC.
the average response accuracy rate under alcohol is lower than
the normal state, and the average latency time under alcohol is Sometimes, the performance measures do not change as
longer than the normal state. Decreasing amplitudes of later blood alcohol levels increase, specific changes in the spectral
peaks of ERPs were found in the ERP data. Meanwhile, it was
composition of the electroencephalographic (EEG) signal and
concluded that the right side of brain has been impaired by the
alcohol more intensive than the left side. It is concluded that in amplit
