But a high reading doesn\u2019t always mean a conviction. Breathalyzers are not infallible, and several factors can lead to inaccurate results. Machine errors, improper testing procedures, and even certain medical conditions can all impact the outcome. If you\u2019ve been charged with a DUI, it\u2019s important to know that breathalyzer results can be challenged. A closer look at the details may reveal weaknesses in the case against you.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Breathalyzer Tests Work<\/h2>\n\n\n\n<p>A breathalyzer estimates blood alcohol content (BAC) by measuring alcohol levels in a person\u2019s breath. When you exhale, the device detects ethanol molecules and converts that data into a BAC reading. Law enforcement officers use these tests because they provide quick results, but they don\u2019t directly measure blood alcohol levels\u2014only an estimate based on breath.&nbsp;<\/p>\n\n\n\n<p>To ensure accuracy, breathalyzers require proper calibration and must be administered correctly. However, several factors can interfere with readings, including residual mouth alcohol, medical conditions, and even environmental influences. Understanding how these tests function can help identify possible errors in the results.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common Issues with Breathalyzer Accuracy<\/h2>\n\n\n\n<p>Breathalyzer tests are widely used in <a href=\"https:\/\/justiciacentral.com\/en\/criminal-law\/dui\/\">DUI cases<\/a>, but they are not always reliable. Several factors can lead to inaccurate results, potentially giving a false impression of intoxication.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Improper calibration and maintenance<\/strong> \u2013 Breathalyzers must be regularly calibrated to function correctly. A device that hasn\u2019t been maintained properly can produce skewed readings.<\/li>\n\n\n\n<li><strong>Officer error<\/strong> \u2013 Administering the test requires specific procedures. If the officer skips a step or misuses the device, the results may be unreliable.<\/li>\n\n\n\n<li><strong>Medical conditions and diet<\/strong> \u2013 Acid reflux, diabetes, and low-carb diets can cause breath alcohol readings that do not reflect actual intoxication.<\/li>\n\n\n\n<li><strong>Mouth alcohol and residue<\/strong> \u2013 Mouthwash, cough syrup, and even burping before the test can leave traces of alcohol in the mouth, leading to artificially high BAC readings.<\/li>\n\n\n\n<li><strong>Environmental factors<\/strong> \u2013 Certain chemicals, including paint fumes and gasoline vapors, can interfere with breathalyzer sensors and produce inaccurate results.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Legal Strategies to Challenge Breathalyzer Results<\/h2>\n\n\n\n<p>A breathalyzer reading is not always dependable evidence in a DUI case. There are several ways to challenge the results and raise doubts about their accuracy. If the breathalyzer test was improperly conducted or the machine was not maintained correctly, we can argue that the results should not be used against you.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Questioning calibration and maintenance records<\/strong> \u2013 Breathalyzers require regular maintenance and calibration. We can request the device\u2019s maintenance logs to check for lapses. If the machine was not calibrated correctly, the BAC reading may be inaccurate.<\/li>\n\n\n\n<li><strong>Challenging officer training and procedures<\/strong> \u2013 Officers must follow strict protocols when administering a breath test. If they failed to observe the required waiting period or misused the device, we can argue that the test results should be thrown out.<\/li>\n\n\n\n<li><strong>Presenting alternative explanations<\/strong> \u2013 Certain medical conditions, dietary habits, or even medications can cause misleading BAC readings. We can provide medical evidence to explain why your test result was inaccurate.<\/li>\n\n\n\n<li><strong>Raising constitutional issues<\/strong> \u2013 If the officer lacked probable cause to stop you or failed to follow proper legal procedures before administering the test, we may be able to challenge the admissibility of the results.<\/li>\n<\/ul>\n\n\n\n<p>A flawed breathalyzer reading does not mean an automatic DUI conviction. There are many ways to fight back.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Happens If Breathalyzer Results Are Challenged Successfully?<\/h2>\n\n\n\n<p>If we successfully challenge your breathalyzer results, the prosecution may struggle to prove intoxication. Without a valid BAC reading, the case often relies on other evidence, such as field sobriety tests or the officer\u2019s observations\u2014both of which can be subjective. In some situations, charges may be reduced to a lesser offense or dismissed entirely.&nbsp;<\/p>\n\n\n\n<p>Even if the case proceeds, weakening the breathalyzer evidence can create doubt, making it harder for the prosecution to meet its burden of proof. Challenging the results doesn\u2019t guarantee a dismissal, but it can significantly improve your chances of a better outcome.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Contact an Experienced Orlando DUI Defense Attorney<\/h2>\n\n\n\n<p>A breathalyzer result is not the final word in a DUI case.
