Even with no alcohol in the driver's system, reaction time can be affected.

Explanation:

Reaction time is the time interval between the generation of a visual, audible stimulus, etc., and motor action. We can say that during driving, the reaction time is the time interval in which the driver sees a child lying in the middle of the street and stops the car in time, before reaching the child, for example.

Alcohol consumption can affect the reaction time to form significant, but even without consuming alcohol, the driver can have their reaction time affected. Research indicates that reaction time revolves around values that correspond to milliseconds and is affected by factors such as emotional state, age, physical fitness, and cognitive level.
