What Is a Breath Test?
A breath test uses a device called a breathalyzer to give law enforcement officers a quick way to determine how much intoxicating liquor is in the driver’s blood.
Breath testing can be done by using either a PAS or an EBT breath testing device.
1. A PAS breath testing device is a small device a law enforcement officer usually uses in the field. Although it gives a general idea if a driver has been drinking, it is not always precise. However, its results can be used as evidence in court.
2. An EBT is a breathalyzer machine usually kept in a police station or jail. It is much more reliable than PAS breathalyzers.
Generally, PAS devices are used before a DUI arrest, while an EBT breathalyzer machine is used after.
How Does a Breath Test Work?
A breathalyzer measures the amount of alcohol in the breath the person exhaled from their lungs. That measurement is known as blood alcohol concentration (BAC).
When a driver who consumed alcohol exhales into the mouthpiece, the device reacts by changing the color of the liquid inside the device. The degree of color change is related to the level of alcohol in their breath, resulting in a numerical value of a person’s BAC.
The same data shows that a healthy adult can experience the effects of a drink after 15 to 45 minutes. After the BAC reaches 0.05%, the person would most likely exhibit the characteristics of intoxication. Having a BAC of 0.08% or more indicates the person is over the legal limit to drive.
Can You Cheat a Breath Test?
There are many myths surrounding passing a breath test, such as holding your breath, using a strong mouthwash, smoking a cigarette, and even sucking on a penny.
However, these are just myths, and they can not help one pass a breath test. What is worse, some of these options can even result in raising one’s BAC. Not drinking and driving is the only way to pass a breath test. Although a driver can refuse to submit to a breath test, this carries significant consequences.
Can You Refuse a Breathalyzer?
All U.S. states have implied consent laws that state drivers have to submit to DUI testing if they are arrested for drunk driving. However, pre-arrest tests are not mandatory. In other words, drivers can deny a breathalyzer, but they have to be aware that it can carry additional consequences and penalties.
While the prosecution would have a hard time proving their case in this scenario, refusing to submit to a breath test is a separate chargeable offense that attracts a driver’s license suspension and other potential penalties. In some states, a driver who refuses to submit to a breath test can be charged with two separate offenses: drunk driving and refusal to submit to a breath test.
In the District of Columbia (DC), police officers must obtain a person’s consent before submitting them for breath testing. After a DUI arrest, the police must read the Implied Consent Act. The Act states that every individual who operates a motor vehicle consents to a chemical test, including a blood test, breath test, or urine test. These tests determine if a driver is under the influence of alcohol.
Although the driver cannot choose which test to submit, they can object to any type of testing based on valid religious grounds. The driver also has to right to refuse every one of these chemical tests.
However, if an accident that resulted in a fatality has occurred, the driver must submit to some of these tests, especially if the law enforcement officer has reasonable grounds to believe the person was intoxicated. In most cases, their blood sample would be taken to a hospital and tested.
The consequences can be particularly harsh if a driver has a prior DUI conviction on their record. So, if you or your loved one has refused a breath test in Virginia and need help, reaching out to a Virginia DUI lawyer is crucial.
