When having a few drinks while at an Illinois bar or restaurant, most people do not have breath testing equipment that they can use to figure out whether they are okay to drive or not. However, evaluating the level of sobriety might not be accurate as the blood alcohol concentration could be higher than one thinks. The following information refers to the estimated BAC for an 160-pound man after consuming the given number of drinks in one hour.

When having two alcoholic drinks, the man may lose some judgement and feel relaxed and warm. Even two drinks can influence the way one drives and could lead to a decline in visual functions and a lessened ability to perform two tasks at once.

After three drinks, the man has a BAC of around .05 percent. He may feel good and have less inhibitions and might exaggerate behavior while having less control of small muscles. He also has impaired judgement and less alertness. This means that one is less coordinated when driving and cannot track moving objects or respond to emergency situations as well. A motorist at this level of inebriation could also have trouble steering.

The man might have less overall muscle coordination and be at the legal limit after consuming four alcoholic beverages in an hour. It is also harder to think, reason and remember with a BAC of .08 percent, and detecting danger is more difficult. This leads to impaired perception and trouble concentrating, which makes driving dangerous. One may not be able to control the speed of a vehicle or process information.

Even when a motorist feels fine, drunk driving charges are taken seriously in Illinois. People who are facing these types of charges may want to have the assistance of a defense attorney in combating them.
