Which statement about a breath-alcohol test is accurate?
Correct answer: A. – It can estimate the probable alcoholic content of a person’s blood
Virginia law authorizes preliminary breath analysis to determine the probable alcoholic content of a person’s blood. Following a qualifying DUI arrest, a chemical breath test may be required, with a blood test used when breath testing is unavailable or physically impossible. Coffee, exercise, or a cold shower does not remove alcohol from the body; only time decreases intoxication.
