Debunking blood alcohol content (BAC) measurement myths

On Behalf of | Oct 7, 2024 | Breath Test Refusal, DUI

Imagine this: You’re out with friends, enjoying a few drinks. You feel fine and decide to drive home. Suddenly, a police officer pulls you over and wants you to take a breathalyzer test. Panic sets in as you remember various things you’ve heard about DUI testing. Are they true? Let’s clear up some common myths about measuring blood alcohol content (BAC) so you can separate fact from fiction if you ever wind up in this situation.

Myth 1: You must consent to testing

One common myth is that you must consent to BAC testing if a law enforcement agent asks you to. While Florida’s implied consent law means you agreed to test when you got your driver’s license, you still have rights. Knowing that these tests are to give police evidence of impairment, you can choose not to consent to testing.

However, refusing to test can result in immediate penalties, such as a license suspension and disqualification from diversion program eligibility.

Myth 2: Technology is always right

Many believe that breathalyzer devices are always accurate. This is not true. Various factors, such as the device’s maintenance and calibration, can affect the results. Sometimes, even the way you breathe can impact the reading. This is also true for other testing methods like phone apps, personal devices and breath test machines in stores and bars.

Myth 3: You can beat the tests

Some think they can trick the BAC test by using mouthwash, sucking on a coin or other tricks. These methods do not work and can even backfire. Breathalyzers are designed to detect alcohol in your breath, and temporary fixes won’t fool the technology. Only time can lower your blood alcohol level.

Myth 5: BAC levels rise and fall predictably

A common misconception is that BAC levels rise and fall in a predictable manner, making it easy to estimate when you’re sober enough to drive. In reality, BAC levels can fluctuate due to various factors, including the rate of alcohol absorption and metabolism, which can differ from person to person.

Knowing the truth about BAC testing is essential for anyone at risk of or charged with drunk driving in Florida. By debunking these myths, you can better protect yourself and make informed decisions.
