Are Breathalyzers Reliable at Proving Intoxication?

Breath testing has been the most common method of investigating and confirming a person’s blood alcohol concentration (BAC). Law enforcement and similar authorities typically use handheld electronic devices known as breathalyzers to test an individual’s breath and obtain a BAC reading. But are these breath testing devices actually reliable? Are they accurate? Do they really prove intoxication?

Continue reading to learn more about breath testing and breathalyzers, including what to do if you believe you have been wrongly arrested after failing a breathalyzer test in Indiana.

Breathalyzer Testing

Breathalyzers are science-based electronic devices that are designed to read and compute blood alcohol levels based on breath. There are different types of breathalyzers. Some are designed with fuel cells that generate an electric current, while others use infrared light or chemical reactions.

The average person has no idea how these scientific electronic devices work, so many people tend to blindly trust whatever reveals. But like all manufactured commodities, especially electronic ones, design flaws and happen. In such a case, breathalyzers might incorrectly or inaccurately process the blood alcohol concentration in a person’s breath.

Breathalyzer Test Reliability

So, how reliable are these breathalyzers? Possibly not so much, at least not all the time. According to a post in the New York Times, thousands of people have been arrested based on flawed breath testing results over the years, and courts across the country have thrown out more than 50,000 tests.

As most fragile computer-based electronic devices go, breathalyzers require routine maintenance and care, including precise calibration. Not only must these devices be set up properly, but they must also be used correctly and by a certified operator. And the unfortunate truth is that the standards for proper breathalyzer usage and maintenance are not highly regulated.

Most law enforcement agencies are not monitored on how well they take care of or calibrate their BAC-measuring machines, how well they train their staff to use them, and how well they store their data. With all of these factors at play, there are many variables that can cause breathalyzers to compute inaccurately, and therefore, give unreliable BAC test results.

Get Yourself a Lawyer After Failing a Breath Test

Unfortunately, most law enforcement officials will take whatever reading the breathalyzer gives them and use it as just cause to arrest a person for public intoxication or drunk driving. For this reason, it is important to obtain professional and private criminal defense legal representation to fight your criminal charges. Good criminal defense attorneys have the resources, knowledge, and skills to reduce your charges or dismissed them entirely based on an unjust arrest.

Reasonable Suspicion for Traffic Stops

When it comes to DUI traffic stops, it is important to understand the difference between reasonable suspicion and probable cause. In all cases of traffic stops, whether a driver has been drinking alcohol or not, law enforcement must have reasonable suspicion that a driver has committed a traffic violation or infraction before pulling them over. Once pulled over, law enforcement must then establish probable cause to make an arrest.

In order for a police officer to legally arrest a person for a DUI, there must be probable cause, which is evidence that supports an officer’s reasonable belief that a driver is intoxicated, or under the influence of a drug or controlled substance.

Reasons You Might Have Been Pulled Over for Drunk Driving

Both reasonable suspicion and probable cause can be a means to a DUI arrest. Police officers can use either principal, or both, to conduct a legal traffic stop and establish an arrest. The types of probable cause or reasonable suspicions can vary depending on each situation of intoxicated driving. However, these are the top 5 reasons why police officers pull people over and arrest them for drunk driving:

Traffic Violations

Traffic violations are one of the top reasons why people are pulled over, regardless of alcohol involvement. Common traffic violations include expired license plates, illegal U-turns, illegal parking, failure to use turn signals, ignoring traffic signs, running red lights or stop signs, and most recently, texting and driving.

Reckless Driving

Poor driving is another common reason why police officers pull people over. If a person is exhibiting bad or reckless driving, a cop can legally pull them over to conduct a traffic stop. Examples of reckless or bad driving include speeding, following too closely, failing to yield, ignoring traffic signs, driving too slow, and similar risky behaviors.

Car Accidents

Speaking of risky behaviors, law enforcement can use the occurrence of a car accident to establish reasonable suspicion to question a driver. Whether you are at fault for a car accident or not, police can question you, and if it comes down to it, arrest you for a DUI. They would need to make some observations to establish a legal basis for arresting you, though. See below to learn more.

Mid-Stop Observations

Once a police officer has pulled a driver over, they can continue their investigation by keeping their eyes open for tells or signs that a person has been drinking alcohol or using illicit drugs. A cop can establish probable cause and make a DUI arrest if they smell alcohol on your breath, hear you admit to having a drink earlier, see alcohol containers in your car, catch you in a lie, and more. Other signs that officers use as evidence of drunk driving include slurred speech, glossy or red eyes, dilated pupils, slowed movements, incoordination, insubordination, crying, and hostility.

BAC Testing

To really seal the deal and come in with some valid evidence to support their reasonable suspicion and probable cause, law enforcement relies on field sobriety testing and blood-and-alcohol (BAC) testing. Also known as chemical testing, a breathalyzer is one of the most common devices used during traffic stops to determine a driver’s level of alcohol in their system, and therefore, reveal how much they’ve had to drink within a 24 hour time period.

The legal limit is 0.08 percent BAC. If you blow this or more, you will be arrested on DUI charges. Upon being arrested, and with your consent, law enforcement will request to have your blood drawn and tested to confirm a precise BAC value.

Field sobriety testing is another strategy used by law enforcement to establish probable cause for a DUI arrest. Walking the line, touching the nose, and following the pen with the eyes are typical phases of a field sobriety test.

Breathalyzer Testing Myths and Misconceptions

Sucking on a Penny

For many decades now there has been a rumor going around suggesting that if you suck on a penny, you can pass a breathalyzer test. But this is very false. Furthermore, coins are incredibly unsanitary, so you should never put them in your mouth. Besides, if a police officer catches you with a penny in your mouth before they administer their breath test, it can be used against you by the prosecutor who may suggest that you knew you are guilty and were trying to conceal your intoxication.

Refusing a Breath Test

Many people believe that if you refuse a breathalyzer, law enforcement has no way to retrieve blood alcohol content (BAC) evidence against you, and therefore, cannot charge you for an intoxication offense. Not only is this completely untrue but refusing a breathalyzer when requested by law enforcement is a separate offense in itself and will immediately suspend your driver’s license for six months without any questions. Here in Indiana, when you register your vehicle, you automatically consent to breathalyzer testing, and agreed to driver’s license suspension in the event that you refuse one.

Drinking Vodka

There is a rumor that suggests that if you drink vodka over all other alcoholic beverages, the smell cannot be detected on your breath by law enforcement if you are ever pulled over or stopped for questioning. But this rumor is untrue as well. Any sort of liquor will have a distinct scent on a person’s breath, and when you’ve been drinking you become nose blind to the smell. Just keep in mind that officers are sober, which means they have a heightened sense of smell for things like liquor and marijuana.
