The impairing effects of alcohol on the brain
Alcohol affects everyone differently. Blood alcohol content (BAC) may be affected by age, gender, physical condition, and amount of food consumed, medication and other factors. Also, different mixed drinks contain different amounts of alcohol, so it's important to know how much alcohol has been consumed, not just how many drinks the person has had.
Sequence of effects on the body
Alcohol is absorbed into the blood stream very quickly. As blood alcohol levels start to rise, the brain becomes increasingly sedated or drugged.
The first part of the body affected by alcohol is the brain, particularly the part of the brain that allows you to think clearly and make good decisions. Its sedative effects impair judgment in a way that is usually not noticed by the drinker. The part of the brain that controls social inhibitions is also affected, causing people to say and do things they normally would not. These effects start with one drink.
- Muscle control
The second part of the body affected by alcohol is muscle control. Due to the small muscles in the eye being very susceptible to the effects of alcohol, vision can be significantly affected, even at low alcohol levels.
Many people wrongly assess their ability to drive after drinking by observing physical dexterity (staggering, etc.). This is incorrect as the greatest percentage of alcohol-related collisions result from faulty thinking during the identification, prediction and decision parts of the driving task and not as a result of poor execution (steering, braking, etc.).
The brain functions that are first affected by alcohol consumption are not only important to our ability to drive safely, but are the same ones required to make rational decisions about not driving after drinking. For this reason, you must make the decision to separate your drinking and driving and make the necessary alternate transportation plans before you have that first drink! It does not make sense to drive after drinking. For more information on the effects of alcohol and drugs, contact your nearest Alcohol and Drug Services office.
How alcohol affects you
|BAC||Typical Effects||Predictable Effects on Driving|
|.16% and greater||

Likelihood of a crash
As the concentration of alcohol in the bloodstream increases, the body loses more and more of the functions required to drive safely. The increased likelihood of a crash begins long before drivers feel drunk or severely impaired.
It is important to understand BAC and its impact on driving at various levels. Driving impaired, even at low levels, is a real gamble.
The only truly safe BAC is 0%.
.05-.09% (11 x increased likelihood) > .10-.14% (48 x) > .15+% (380x)
BAC and time
Only time can eliminate alcohol from the body. You cannot successfully sleep off a night of heavy drinking in a few hours. If you go to bed intoxicated with a BAC of .25% and alcohol leaves the system at a rate of approximately .015% per hour, this might be a picture of what happens:
|Midnight||goes to bed||.25|
|7 a.m.||gets up for work||.145|
|8 a.m.||feels dry mouth||.13|
|9 a.m.||at work||.115|
|10 a.m.||still legally intoxicated||.1|
|11 a.m.||spills coffee||.085|
|Noon||still feels tired||.07|
|1 p.m.||mind feels foggy||.055|
|2 p.m.||feeling irritable||.04|
|3 p.m.||starting to feel better||.025|
|4 p.m.||head clearing||.01|
|5 p.m.||goes home||.00|
