If you’ve ever been pulled over by a police officer and asked to take a breathalyzer test, you know just how scary and intimidating it can be. Your heart starts racing and you can no longer think clearly.
Should you take it? Can you legally say no? What happens if you do? These are the rapid-fire questions a lot of people don’t think about until they’re sitting in their car with flashing lights behind them. And truth be told, this is the wrong time to be figuring it out.
The answer isn’t as simple as “yes, always refuse” or “no, never refuse.” It depends on your situation, your state’s laws, and an honest assessment of where you stand. Here’s what you actually need to know.
Understanding Your Rights
Let’s start with the legal reality. In the United States, you technically have the right to refuse a breathalyzer test during a traffic stop. However, that right comes with consequences built directly into the law. Every state has what are called implied consent laws, which essentially mean that by obtaining a driver’s license and operating a vehicle on public roads, you’ve already agreed to submit to chemical testing if law enforcement has reasonable cause to request it.
Refusing the test doesn’t make the situation disappear. In most states, refusal results in an automatic license suspension, often ranging from six months to a year or more for a first offense. That suspension typically kicks in regardless of whether you’re ever convicted of a DUI. Some states also allow refusal to be used as evidence against you in court, meaning a prosecutor can argue to a jury that you refused because you knew you were over the legal limit.
So the short answer is yes, you can say no. But you should go in knowing exactly what that decision is probably going to cost you.
The Case for Refusing
There are legitimate reasons why someone might choose to refuse, and it’s worth understanding the logic before dismissing it entirely.
If you’ve been drinking and you’re fairly confident you’re over the legal limit, refusing the breathalyzer doesn’t eliminate the evidence against you, but it does remove one of the most straightforward pieces of it.
A BAC reading of 0.12 percent is a concrete number that’s hard to argue against in court. Without that number, a defense attorney has more room to work with. Prosecutors still have other tools – such as field sobriety tests, officer observations, dashcam footage, etc. However, a chemical test is usually the centerpiece of a DUI case.
There’s also the matter of breathalyzer accuracy. These devices are known for messing up and giving out inaccurate results. Things like calibration issues, improper administration, certain medical conditions, and even some foods or medications can affect readings. If you believe a test might produce a false or inflated result, refusing could theoretically protect you from inaccurate evidence being used against you.
The Case Against Refusing
For most people in most situations, refusing a breathalyzer is probably not the right move – and here’s why.
If you haven’t been drinking, or if you’ve had a drink or two but believe you’re under the legal limit, refusing actually puts you in a worse position. You’re guaranteeing yourself a license suspension and potentially handing prosecutors a narrative that will work against you. And you’re doing this all to avoid a test that likely would have cleared you.
Even if you have been drinking, the automatic consequences of refusal in many states are severe enough that they can rival or exceed the penalties for a first-offense DUI conviction. A year-long license suspension without the possibility of a restricted license can upend your ability to get to work and handle everyday responsibilities.
Roadside vs. Station Breathalyzers
One thing that usually gets overlooked in this conversation is that not all breathalyzer tests are created equal, legally speaking.
The handheld device an officer might ask you to blow into on the side of the road is typically called a preliminary alcohol screening device. In many states, you can refuse this roadside test with fewer consequences than refusing a formal chemical test administered at a police station or hospital. The roadside device is typically used to establish probable cause for an arrest, while the formal test administered afterward carries the full weight of implied consent laws.
Knowing this distinction matters. In some states, refusing the roadside breathalyzer while complying with the official test after an arrest is a legally savvy choice. In others, both carry the same consequences. The rules vary significantly depending on where you are, which is why understanding your specific state’s laws before you ever find yourself in that situation is genuinely valuable.
Talk to a DUI Attorney Either Way
Whether you took the breathalyzer or refused it, the most important thing you can do is get in touch with a drunk driving attorney as quickly as possible. The window to contest an automatic license suspension is usually very short, and missing that deadline can impact your options.
An experienced attorney will help you determine the best way to proceed in light of your specific circumstances and what happened at the traffic stop. Lean on their advice as much as possible!
