In Maryland, it is considered intoxication per se, or driving while intoxicated, if an individual's blood alcohol level is .1 grams of alcohol per 100 milliliters of blood or per 210 liters of breath.
Many individuals drive or attempt to drive after they have consumed too much alcohol.
It is irrelevant if you do not feel or look as though you are under the influence, or if the impairment results from a prescription or over the counter drug. No two people will react to a drink or a drug in the exact same way. For example, your body weight or whether or not you have eaten recently will have an impact on how alcohol effects you. Furthermore, if you are tired, the effect of alcohol is greater and the longer you take to consume each drink and the longer you wait between drinks, the less effect they will have. The most common symptoms, according to the National Highway Safety Patrol, that police officers look for when searching for drunk drivers on the roadway are turning with a wide radius, straddling the center of the lane or weaving.
