At a BAC level of .02, expect to experience some loss of judgment accompanied by a feeling of relaxation, slight body warmth, and an altered mood. However, if you are behind the wheel, be aware that this level of alcohol in your system results in a decline in your visual functions, making it difficult to track moving targets, and a decline in your ability to perform multiple tasks, making it challenging to divide your attention. Stay safe and avoid operating a vehicle when consuming alcohol.

At a blood alcohol concentration (BAC) of 0.05, one may experience exaggerated behavior, loss of small-muscle control such as eye focusing, impaired judgment, a sense of well-being, lowered alertness, and a release of inhibitions. These effects can have a significant impact on one's ability to drive safely, leading to reduced coordination, difficulty tracking moving objects, impaired steering ability, and diminished response to emergency driving situations. It is essential to recognize the predictable consequences of drinking and driving, and always prioritize the safety of oneself and others on the road.

When your blood alcohol content (BAC) reaches .08, several detrimental effects can occur. You may experience a decline in your muscle coordination, resulting in poor balance, speech, vision, reaction time, and hearing. Additionally, your ability to detect danger will diminish, as will your judgment, self-control, reasoning, and memory. These effects can have a significant impact on your driving abilities, specifically in terms of concentration, speed control, short-term memory loss, reduced information processing capability (such as signal detection and visual search), and impaired perception. Be aware of these dangers and take measures to avoid impaired driving.

With a blood alcohol concentration (BAC) of .10, you can expect a significant impact on your physical abilities and decision-making skills. Your reaction time and coordination will worsen, and talking will be difficult due to slurred speech. Additionally, your ability to maintain your lane and brake properly will be hindered while driving. It's crucial to avoid getting behind the wheel after consuming alcohol to ensure the safety of yourself and others on the road.

At a blood alcohol concentration (BAC) level of .15, you could experience significant physical effects such as reduced muscle control and potentially vomiting (though slow consumption or alcohol tolerance may reduce this risk). Alongside these physical symptoms, you may also experience a major loss of balance.

These effects will have a serious impact on your ability to drive safely. Research shows that at this level of intoxication, you are likely to experience substantial impairment in your vehicle control, ability to focus on the task of driving, and your ability to process necessary visual and auditory information. It's important to be aware of the risks and to plan ahead to avoid getting behind the wheel when you are not in a fit state to drive safely.
