There’s no good universal answer here — and anyone who tells you there is isn’t being straight with you. Both choices carry serious consequences, and the right call depends almost entirely on facts specific to your situation: how much you had to drink, what the officer already observed, and what other evidence exists against you.
What follows is an honest breakdown of what each path actually means.
First: This Is Not the Roadside Test
Before getting into the decision itself, it’s worth being clear on which test we’re talking about. The portable breath test (PBT) administered at the roadside before your arrest is different from the official chemical test at the station. The PBT results are generally not admissible as BAC evidence at trial. The station test is.
The official chemical test at the station — typically a DataMaster breathalyzer, though blood and urine tests are also options depending on circumstances — is what New York’s implied consent law applies to. This is the test this post is about.
What Happens When You Take the Test
Taking the official breathalyzer test means you’re providing the prosecution with a numerical BAC reading. That number drives what happens next.
If your BAC is below 0.08%, the result actually helps you. It directly contradicts the officer’s claim of intoxication and can be a powerful piece of defense evidence. Taking the test in this scenario is almost always the right call.
If your BAC is between 0.08% and 0.17%, you’re providing the prosecution with per se evidence of DWI — a clean, objective number that makes conviction significantly easier. The prosecution no longer needs to rely solely on the officer’s subjective observations or your field sobriety test performance. That said, breathalyzer accuracy is a legitimate defense issue — the machine’s calibration, maintenance records, and the 15-to-20-minute observation period required before testing can all be challenged. Taking the test doesn’t mean the result is unassailable.
If your BAC is 0.18% or higher, you’re facing an aggravated DWI charge on top of standard DWI, with stiffer fines, longer license revocation, and more limited plea bargaining options. Providing this number to the prosecution essentially hands them their strongest possible case.
What Happens When You Refuse
Refusing the official chemical test at the station triggers automatic consequences that are separate from — and in addition to — any criminal charges:
| Consequence | Detail |
|---|---|
| Immediate license suspension | Happens at the moment of refusal |
| Minimum 1-year license revocation | Imposed by the DMV after an administrative hearing |
| $500 civil penalty | Minimum fine, separate from any criminal fines |
| No conditional license | You cannot get a hardship or conditional license during the revocation period |
| Refusal used as evidence | The prosecutor can tell the jury you refused, arguing it shows you knew you were intoxicated |
These penalties are administrative — they’re imposed by the DMV regardless of whether you’re convicted of DWI in criminal court. Even if your criminal case is dismissed or you’re found not guilty, the license revocation stands unless you win the separate DMV administrative hearing.
What happens when you refuse the breathalyzer is a fixed set of consequences. The strategic question is whether avoiding the BAC number is worth accepting all of them.
The Criminal Case Angle
Refusing does not prevent the prosecution from charging you with DWI. Instead of a per se DWI based on your BAC, they charge you with common law DWI based on observed impairment — your driving behavior, your performance on field sobriety tests, the officer’s testimony about slurred speech or the smell of alcohol, and the refusal itself as evidence of guilt.
This is a weaker case for the prosecution in most instances. Officer observations are subjective. Field sobriety test results can be challenged. Without a BAC number, there’s no single piece of objective data tying you to a specific level of intoxication. That’s a meaningful advantage for your defense attorney.
However, the advantage comes at a real cost. A full year without driving privileges — and no access to even a conditional license — is a serious hardship for most people. Depending on where you live and whether driving is tied to your employment, this can be a life-disrupting penalty.
The Decision You’re Making in Real Time
This decision has to be made within a narrow window — often within minutes of arriving at the station. New York law gives you a limited opportunity to speak to a lawyer before taking the chemical test, but the police are not required to wait indefinitely. If you ask for a lawyer and the delay becomes excessive, it may be treated as a refusal.
What should drive the decision, if you can get there quickly, is an honest assessment of your likely BAC. If you had two drinks hours ago and feel confident you’re well under the limit, taking the test removes uncertainty and can work in your favor. If you know you drank heavily, and the number is going to be significantly over the limit, refusing removes that per se evidence — but you’re accepting the administrative penalties as the cost of doing so.
What happens when you’re arrested and brought to the station unfolds quickly. The booking process, the chemical test window, and the arraignment all follow in sequence. Understanding this timeline in advance is part of knowing how to navigate the moment.
One Option That’s Sometimes Overlooked
If you take the official test, New York law gives you the right to have an independent chemical test administered by a qualified person of your choosing at your own expense — immediately following the official test. Requesting a blood test after the breathalyzer can give your attorney a second data point to compare against the official result and potentially challenge its accuracy. This option disappears if you refuse the official test entirely, since you must submit to the official test first to preserve the right to an independent one.
Refusing both the breath and drug testing triggers the same implied consent penalties regardless of which test was offered, so that distinction matters less in terms of consequences — but the independent test option is only available if you take the official test first.
For the full legal framework governing this decision in New York, Vehicle and Traffic Law § 1194 sets out the implied consent requirements and the administrative process that follows a refusal.
An experienced DWI defense attorney can help you think through this in the moment, which is exactly why invoking your right to counsel as early as possible is worth doing, even if the window to consult before the test is limited.
