Is a Maryland DUI breathalyzer truly accurate?Written by ruxandra
In Maryland, just like in all other states in the US, the driver who has a BAC (blood alcohol content) of 0.08 or higher will be considered legally intoxicated. As a result, the driver may be charged with a DUI (driving under the influence). The BAC can be determined instantaneously with the help of a Maryland DUI breathalyzer. If you were caught driving under the influence, you should contact a personal injury lawyer from Maryland.
There are three methods of determining the BAC of a driver in the US. The most accurate is the Maryland DUI blood test, although these tests are inconvenient and invasive. To analyze the blood of the driver, a sample has to be drawn from the subject’s veins in a clinical or hospital setting. Because of the long process of determining the BAC of the driver, breath tests called breathalyzers are at hand for the police officers. These handheld devices are portable, lightweight and easy to administer. Breathalyzers can also be used by drivers to see the level of their alcohol level and determine if it is safe to drive or not.
The breath test results can help a police officer to establish probable cause for a DUI arrest, but the results of the test are not admissible in court. This happens because of some factors that can influence the results of the breath test. With the help of an Annapolis injury attorney, you will challenge the reliability of a breathalyzer and have a strong Maryland DUI defense.
Today the price of a breathalyzer has declined considerably while the breath testing technologies have improved. As a result, more and more drivers have their own breathalyzer to gauge the level of BAC after consuming alcohol. Any Annapolis injury lawyer will recommend you to have in your car a breathalyzer and to test yourself after you have consumed alcohol beverages.
The sensor technologies
All the handheld breathalyzers work in the same way. You blow in the mouthpiece, and the breathalyzer provides the level of your BAC. But the accuracy of all breathalyzers varies, as well as their technology. There are two main categories of breathalyzers, depending on the technology they have.
- Semiconductor sensors for personal use
- Highly accurate fuel cell technology
Most breathalyzers use the semiconductor sensor which has a thin oxide material that is less precise than platinum fuel cell sensor technology. These breathalyzers can give false positives from different substances, like ketone which has a similar structure as alcohol but is produced naturally in the human body. If the police tested you with a breathalyzer, you were found positive, but you did not consume any alcohol, you should contact an Annapolis injury attorney. The Annapolis injury lawyer will recommend you to ask the police officers for a Maryland DUI blood test and to prove that you did not consume alcohol. Even if the police decide that you were driving under the influence, the blood test will be the best Maryland DUI defense you have. The breathalyzers with fuel cell sensors will provide a more accurate reading. Law enforcement officers use this type of breathalyzer to determine the BAC levels of DUI drivers.
The Maryland DUI breathalyzer used by the police officers can be accurate but are still not admissible in court. If you were caught driving after drinking alcohol, you should contact the best personal injury lawyer in Maryland at (443) 569-3950 or at email c[email protected].
