If you’ve been stopped on suspicion of DUI in Nevada, you might wonder: Can you refuse a blood alcohol test? It’s a fair question—and one with serious legal consequences.
At Spartacus Law Firm, we defend individuals charged with DUI and other criminal offenses in Las Vegas. In this guide, we’ll break down Nevada’s laws on DUI testing, your rights during a traffic stop, and what happens if you say “no” to a blood, breath, or urine test.
Understanding your rights before you’re pulled over can mean the difference between a conviction and a successful defense.
Implied Consent Laws in Nevada
Nevada has an implied consent law, which means that by driving on Nevada roads, you automatically consent to submit to chemical testing if you’re lawfully arrested for DUI. This includes breath, blood, or urine tests to determine your blood alcohol concentration (BAC) or the presence of controlled substances.
So, can you refuse a blood alcohol test? Technically, yes—but you’ll face immediate and long-term consequences.
When Are You Required to Take a BAC Test?
Nevada law allows law enforcement to request a chemical test (blood, breath, or urine) if they have reasonable grounds to believe you’re driving under the influence. This can happen:
- After a traffic stop and observation of impairment
- At a DUI checkpoint
- After an accident
- If you’re arrested for DUI
The officer typically chooses the type of test. You may be asked to take a breath test first, and if unavailable—or if drugs are suspected—a blood test may be requested.
Can You Refuse a Blood Alcohol Test?
Yes, you can refuse, but doing so comes with serious consequences under Nevada law. Refusal isn’t a get-out-of-jail-free card—it may actually make your situation worse.
Here’s what can happen if you refuse a blood alcohol test:
1. Automatic Driver’s License Revocation
Refusing a chemical test triggers automatic license revocation by the Nevada DMV, regardless of whether you’re later convicted of DUI.
- First refusal: 1-year license revocation
- Second refusal within 7 years: 3-year license revocation
This is a civil penalty and separate from any criminal DUI charges.
2. Forced Blood Draw
Nevada law allows police to obtain a warrant for a forced blood draw if you refuse to submit to testing. In some cases—especially involving accidents or prior DUI convictions—no warrant is needed, and the officer can use reasonable force to perform a blood draw.
3. Use of Refusal as Evidence
If your case goes to trial, prosecutors can argue that your refusal to take the test indicates consciousness of guilt. This can influence a jury and hurt your defense.
When Can Police Force a Blood Test Without Consent?
Under NRS 484C.160, law enforcement can perform a non-consensual blood test without a warrant if:
- You have two or more prior DUI convictions within the past 7 years
- There is a death or serious bodily injury as a result of the suspected DUI
- You’re on probation or parole for a previous DUI offense
In these cases, your refusal won’t stop officers from obtaining your blood sample. They can use reasonable force to do so.
DUI Checkpoints and Blood Tests in Nevada
Las Vegas police frequently use DUI checkpoints, especially on weekends and holidays. If you’re stopped and suspected of DUI:
- Officers may ask you to perform field sobriety tests
- You may be asked to take a preliminary breath test
- If arrested, you’ll be asked to take a chemical test (blood or breath)
Refusing at a checkpoint carries the same consequences as refusing during any other DUI investigation. Your license can be revoked, and your refusal can be used against you in court.
Is It Ever a Good Idea to Refuse a BAC Test?
Some people refuse a BAC test hoping to avoid giving the prosecution hard evidence. While this strategy occasionally helps, it often backfires in Nevada due to the harsh penalties.
Unless there is a strategic legal reason—and unless advised by an attorney—it’s usually not in your best interest to refuse a blood alcohol test. The automatic license suspension and possibility of forced testing often outweigh any perceived benefits.
What Happens After You Refuse a Blood Alcohol Test?
Refusing a chemical test can change the course of your DUI case significantly. Here’s what to expect:
Immediate Consequences
- Your driver’s license will be confiscated on the spot
- The DMV will issue a temporary license good for 7 days
- You’ll receive a notice of revocation
DMV Hearing
You have 7 days from the date of the notice to request a hearing with the DMV to contest the license suspension. Spartacus Law Firm can represent you at this hearing and fight to keep your driving privileges.
Criminal Case
If you’re charged with DUI, your refusal will be introduced as evidence. The prosecution may argue that you refused testing to hide your level of impairment.

FAQs: Refusing a Blood Alcohol Test in Nevada
Is refusing a blood test the same as refusing a breath test?
Yes, refusing a blood test carries the same consequences as refusing a breath or urine test in Nevada. All are considered chemical tests under the state’s implied consent laws. Refusal of any type of test can lead to license suspension and be used against you in court.
Will I lose my license if I refuse a BAC test?
Yes, refusing to take a BAC test results in an automatic revocation of your driver’s license. A first-time refusal leads to a 1-year suspension, while a second refusal within 7 years results in a 3-year suspension. This penalty applies regardless of whether you’re ultimately convicted of DUI.
Can police force a blood test if I refuse?
In certain cases, yes—especially if you have prior DUI convictions, caused an accident involving injury, or are on DUI probation. Police may perform a forced blood draw without your consent and sometimes without a warrant. Courts generally uphold this as legal under Nevada law.
Should I refuse a blood alcohol test to avoid a DUI charge?
In most cases, refusing a BAC test does more harm than good. It may not prevent a DUI charge and often results in harsher penalties, including license suspension and the possibility of forced testing. It’s best to consult with a DUI attorney before making that decision.
