The invention discloses a drunk driving simulation method, which comprises the following steps of: S1: setting the blood alcohol concentration of drunk driving simulation; S2: in a driving simulation process, according to the blood alcohol concentration and simulation car speed, dimming the visual picture of a driving simulator; S3: when the blood alcohol concentration exceeds a threshold value, carrying out visual hallucination simulation; S4: within set time, detecting a driving simulation state, and judging whether a traffic accident happens or not, and carrying out traffic accident simulation if the traffic accident happens; and S5: otherwise, increasing a traffic dangerous case circumstance occurrence frequency in the driving simulation process, and returning to the S4 to continue the driving simulation. On the basis of the setting of the blood alcohol concentration of the drunk driving simulation, a visual picture blurry phenomenon, a visual hallucination phenomenon and an operation time delay phenomenon which appear after the drunk driving are simulated in the visual picture of the driving simulator, so that a driver can deeply understand hazards brought by the drunk driving under a situation that the driver is sober, and the drunk driving simulation method has significance for guaranteeing the safety of the driver and reducing traffic accidents.
