It is a situation that every motorist dreads. Being pulled over by a police officer for DUI can be intimidating. If you believe that you are safe just because you have had a couple of alcohol beverages and are confident that you will clear the breathalyzer test, you may not be entirely right. There are ways that a police officer can influence your breathalyzer reading, without you even knowing it.
How can the officer do this? What he does is manipulate your pattern of breathing as he is administering the breathalyzer test. It is scientifically proven that the concentration of alcohol in your breath changes considerably during the breath. The first part of the breath is likely to contain the least concentration of alcohol. In fact, at this stage, you are very likely to register below the .08% level. However, as you begin to inhale more deeply, you’re much more likely to be in dangerous territory. The last part of your breath actually contains a higher concentration of alcohol.
A police officer knows this, and may ask you while you are taking the breathalyzer test to breathe harder. If you breathe deeper and harder, the breathalyzer is likely to detect more traces of alcohol in the last part of your breath. You are therefore much more likely to fail the breathalyzer test or register at or above the .08% level.
That means that you’re possibly looking at a DUI arrest, even though you may not be intoxicated at all. It’s highly likely that you will be very confused at such a time, especially because you do not believe that the number of alcoholic beverages that you had were sufficient for you to register at the maximum permissible limit.
Just because you have registered at the maximum permissible level or higher on a breathalyzer does not mean that a conviction is guaranteed. The first thing that you need to do when you have been arrested for DUI is immediately get in touch with a Denver DUI defense lawyer.
