Effects of Alcohol on Driving Performance

Alcohol impairs driving. That fact, established by epidemiological data together with many controlled studies of alcohol and driving skills, is well known and generally accepted. What is less well understood is that impairment of the most important skills can occur at a very low blood alcohol concentration (BAC).


Data from laboratory experiments indicate that all of these functions are impaired by alcohol, although they differ in the extent of their impairment at any given BAC.

The following discussion highlights recent research on the effects of alcohol on those brain functions involved in driving a motor vehicle:

1. Psychomotor skills
2. Vision
3. Perception
4. Tracking (steering)
5. Information processing
6. Attention

And these effects lead you to an accident. so,
Don't drink and drive.
