What factors influence a Breathalyzer test?

On Behalf of | Sep 21, 2023 | DUI Charges |

When a Maryland driver is pulled over on suspicion of driving under the influence of alcohol, the officer may also ask the driver to blow into a device known as a Breathalyzer. Even those who have never taken a Breathalyzer test are likely aware of these devices. They are used to determine blood alcohol content (BAC). However, like all machines, these devices are not 100% accurate. Here are a few things that could affect a Breathalyzer test. 

Influencing factors 

There are several factors that can affect a person’s BAC and may influence Breathalyzer tests. Body composition is a key factor in BAC levels. For instance, those who have a smaller stature often experience intoxication quicker. Yet, those with a higher body fat percentage can have a higher BAC due to a greater concentration of alcohol in their lean tissues, since body fat doesn’t absorb alcohol. Also, drinking on an empty stomach can make for a faster absorption of alcohol and play a role in BAC levels. 

Breathalyzers and DUI charges 

The amount of alcohol consumed over a period of time will typically determine blood alcohol content level. However, Breathalyzers measure the amount of alcohol that is exhaled, so they don’t actually measure BAC. Even though these machines are not fully accurate, a false positive reading could still lead to a driver getting hit with a DUI charge. Any individual in Maryland who receives DUI charges can get help by consulting a criminal defense attorney. An experienced lawyer can give invaluable guidance while defending the rights of the client.
