What tool detects alcohol in a person's body?

• A. Blood Test
• B. Breathalyzer
• C. Urine Test
• D. Field Sobriety Test

Answer: (B)

Measuring alcohol in the body is done most directly with a breathalyzer. This device analyzes a person’s breath to estimate the blood alcohol concentration, providing a quick, noninvasive reading that's widely used in real-life settings like roadside checks. Because breath alcohol correlates with how much alcohol is in the bloodstream, it gives an immediate indication of intoxication levels. Blood tests can detect alcohol too, but they involve drawing blood and slower lab processing, making them less practical for quick assessments. Urine tests can show alcohol consumption but aren’t precise for current BAC and take longer to obtain results. Field sobriety tests, while useful for judging impairment, don’t measure alcohol content at all—they assess how impairment affects coordination, balance, and cognition. In terms of directly detecting alcohol presence at the time of testing, the breathalyzer is the best fit.
