Why Police Use A Breathalyzer Test Over A Blood Test For DUI & DWI Charges

What A Driver Should Know About DUI Tests

The most common test given to drivers who are suspected of drinking and driving is a breath test or a Breathalyzer test. Although this type of testing for DUI during an arrest is common, it is not the only option officers have to determine a driver’s Blood Alcohol Concentration (BAC) – officers also have the option to test an individual’s urine or blood as well for a suspected DUI or DWI charge offense. Currently under 2023 DUI, DWI laws, every state except Utah impose mandatory penalties for operating a vehicle with a BAC level of 0.08% or greater.

So, with other DUI testing options out there, why do police officers choose the Breathalyzer test? The answer is short and to the point – a breath test allows police officers to avoid obtaining a warrant and therefore circumvent the Constitution. However, national news outlets as recently as this week have reported, the Supreme Court rules cops need a warrant for blood test after drunk-driving arrest situations when a person is suspected of a DUI related offense.

Why Police Use A Breathalyzer Test Over A Blood Test
Review 2023 Breathalyzer and blood test defenses for DUI, DWI charges, and the differences in laws.

Avoiding going into too much detail, a DUI/DWI breath test for alcohol levels can currently be conducted on suspects without having to obtain a warrant. The general situation involves police officers arresting individuals on the suspicion of drinking and driving, bringing individuals to the police station or jail and informing them that refusing to take a breath test can result in being charged with an additional crime. Again, this entire process occurs without police officers ever having to obtain a warrant to complete the Breathalyzer test.

Supreme Court rulings have upheld criminal charges for refusing breath testing, stating this specific test fits within an exception to the requirement of obtaining a warrant. With that being said, these same rulings have also established that breath testing is the only exception – urine and a DUI blood test for BAC readings still require officers to obtain a warrant, which means they cannot threaten further legal action should individuals in question refuse to have urine or blood testing completed.

Because of this exception, it is easy to see why some law enforcement agencies in various states have moved to only offer breath testing for driving under the influence suspects – this type of testing does not require police to obtain a warrant and allows them the opportunity to press additional charges should drivers refuse to complete the testing. In order for officers to legally conduct either of the other two tests, they would have to follow the Constitution and go through the process of obtaining a proper warrant.

It is also important to note that breath testing for BAC is much less accurate than the alternatives of urine and blood draw screening for DUI, DWI cases that check for both alcohol and drug intoxication levels of a driver. The result of a Breathalyzer test can be affected by a number of different factors including temperature, how individuals blow into the device, the testing room’s environment, and other conditions – these types of additional factors do not affect the outcomes of the other two testing types, which in turn makes them much more accurate.

What Can Be Used As a Good Defense For a Breath or Blood Test Over The Legal Limit of .08 BAC?

There are a number of ways how to defend against a recent DUI charge from breath or blood test readings over the .08 BAC legal alcohol limit. After being able to first review a driver’s arrest details, certain defenses such as challenging the accuracy of the Breathalyzer test machine used, and challenging the arresting police officer’s reason for why they requested the test in the first place.

Some other possible ways to defend and fight the charge might be raised based on certain violations of a driver’s constitutional rights before taking the breath test. This is another key reason why having a DUI arrest carefully examined as soon as possible is so crucial to finding the best defense in time, when fighting to get the case dismissed successfully.

What Are The Penalties For a Conviction Of DUI Test Results Reading Over The Legal Alcohol Limit?

In most states for a first DUI offense conviction or guilty plea in 2023, the a minimum cost of fines to expect to pay is $1,200 on average, which is in addition to a DUI criminal conviction that will be on a driver’s permanent record for life.

A 2nd DUI or DWI offense or more of driving under the influence convictions will carry a mandatory jail-time sentence, which begin with penalties of 30 days in jail for a repeat offender upon a second conviction. A third-time offender of a driving under the influence charge will carry a minimum punishment of 6 months time in jail on average.

Even for a first-time DUI conviction, most states will also require a mandatory driver’s license suspension from driving anywhere from 3 months to 2 years. Also, as part of the program to get a license back, most driver’s will also have to get and install an Ignition Interlock device in any vehicle they drive. This Interlock device penalty is typically required for at least one year in most states for a 1st DUI conviction.

In addition to what the mandatory penalties are as previously mentioned, a conviction for DUI or DWI will also drastically raise how much car insurance coverage and premiums will cost for a period of 5 years afterwards.
