What is a .08 alcohol concentration?

Under Texas law "Alcohol concentration" means the number of grams of alcohol per:

(A) 210 liters of breath;
(B) 100 milliliters of blood; or
(C) 67 milliliters of urine.

Unless you are a engineer, chemist, toxicologist or an expert on alcohol and have a calculator, you will not be able to determine whether or not you have an alcohol concentration of .08 or more. The amount of alcohol in each of the above definitions is not equal. Consequently, depending on the test, one test could confirm your innocence while another insinuate your guilt with a .08 or more. A general rule of thumb is that you may have “one beer (12 oz.),” “one glass of wine (4 oz.),” or “one shot of whiskey (1.5 oz.)” per hour. These facts alone should prove the importance of hiring an experienced DWI lawyer who understands the differences
