Breathalyzer vs Blood Test: What’s the Best Choice During a DUI Stop?
When you’re pulled over for a suspected DUI, one of the most critical decisions you’ll make is whether to submit to a breathalyzer or blood test. Both tests are designed to measure your blood alcohol concentration (BAC), but the choice you make can significantly impact your case, especially if you’re facing charges. In this article, we’ll break down the key differences, the legal implications of each option, and how you can use this knowledge to protect yourself during a DUI stop.

Understanding the Differences Between a Breathalyzer and a Blood Test
Breathalyzer Test
A breathalyzer is a portable device that measures BAC by analyzing a sample of your breath. It’s commonly used by police officers during traffic stops as a standard field test due to its quick and convenient results. However, there are a few points to consider:
- Immediate Results: Breathalyzer tests give instant feedback, which can work against you if you’ve had a recent drink and your BAC is still rising.
- Less Accurate: Breath tests can be less accurate compared to blood tests, particularly if they are not properly calibrated or administered. Factors such as breath temperature, mouth alcohol, or recent food intake can skew results.
- No Retesting: Once you blow into the device, there’s no way to reanalyze the sample, which can limit your defense options if the results are in question.
Blood Test
A blood test, on the other hand, measures the alcohol concentration directly in your bloodstream. While it takes longer to process by the Orange County Crime Lab to get the Results online , blood tests are generally more accurate and reliable. Here’s what you should know:
- Higher Accuracy: Blood tests are typically more precise because they measure the exact alcohol concentration in your blood. This accuracy can work in your favor, especially if there’s doubt about the breathalyzer reading.
- Delayed Results: Unlike breath tests, blood tests take time to process at a lab, and the results are not immediate. This delay can potentially help your defense, especially if you suspect a rising blood alcohol level which is a successful DUI defense , which occurs when you drank recently but haven’t yet absorbed all the alcohol into your bloodstream.
- Retesting Option: Blood samples can be preserved and retested, giving your defense team the ability to challenge the initial findings if necessary.
Which Test Should You Choose During a DUI Stop?
The decision between a breathalyzer and a blood test can make a difference in your DUI defense strategy. Here are some things to keep in mind when making that decision:
- Accuracy Matters: If you believe your BAC might be close to or over the legal limit, a blood test could provide a more accurate result, reducing the chances of being falsely convicted. For example, if you just finished drinking and the alcohol hasn’t fully entered your bloodstream, a blood test might reveal a lower BAC than a breathalyzer, which could register a falsely high reading.
- Convenience vs. Reliability: If time is of the essence, and you’re not intoxicated, a breathalyzer might seem like a quick solution. However, if you question the accuracy of the officer’s device, opting for a blood test may give you more time and a better chance to challenge the result.
- Legal Ramifications: Refusing a breathalyzer or blood test can result in automatic penalties, such as license suspension. However, in some cases, refusing a breathalyzer and opting for a blood test later could work to your advantage in court, particularly if you believe the initial results would be inaccurate.
Recommendation: Why You Should Skip Field Sobriety and Breath Tests
As a DUI attorney with years of experience, I recommend the following strategy during a DUI stop, especially if you are not on probation and you’re pulled over in California:
- Skip the Field Sobriety Test: In California, you are not legally required to perform field sobriety tests if you’re not on probation. These tests are subjective and can provide officers with ammunition to justify an arrest, even if you aren’t intoxicated.
- Don’t Answer Questions: You have the right to remain silent. Politely decline to answer any questions regarding how much you’ve had to drink, where you were coming from, or your physical condition. This protects you from saying something that could be used against you later.
- Request a Blood Test Instead of a Breath Test: You can skip the breathalyzer and ask for a blood test. This is a critical move because breath tests are often less accurate and can give officers confidence to embellish their reports. By declining the breath test and opting for a blood test, you force the officer to rely solely on their observations without the support of a breathalyzer result.
- No Ammo for the Officer: When you opt for a blood test, the officer has no field sobriety test results or breath test readings to back up their claims of intoxication. This limits their ability to exaggerate the situation in their report.
- Forcing Honesty: Without these test results, the officer must stick to the facts in their observations and cannot use inflated breathalyzer results to justify the arrest. In my experience, officers are far less likely to embellish when there are no immediate numbers to back them up.
By skipping the field sobriety tests, choosing not to answer questions, and opting for a blood test, you protect yourself from many of the common pitfalls that drivers face during DUI stops. This approach reduces the risk of inaccurate evidence being used against you and ensures that your blood alcohol concentration is accurately measured. This is the strategy I would personally choose in a DUI situation.
Rising Blood Alcohol: A Potential Defense
One of the lesser-known but important aspects of DUI cases is the concept of rising blood alcohol. If you’ve recently consumed alcohol, your BAC could still be increasing when you’re stopped by police. This is significant because if you choose a breathalyzer, it may reflect an artificially high BAC that doesn’t fully represent your intoxication level at the time of driving. Opting for a blood test in this scenario could provide a more accurate reading and potentially lower your BAC result.
Conclusion: Making the Right Choice
When deciding between a breathalyzer or blood test during a DUI stop, it’s crucial to weigh the pros and cons of each method. While breathalyzers provide fast results, they are more prone to error. On the other hand, blood tests are more accurate and offer additional defense opportunities, especially if you suspect rising blood alcohol levels.
If you’ve been arrested for a DUI, consulting with an experienced criminal defense attorney can help you understand your options and develop the best defense based on the circumstances of your case.
Which Orange County courthouse will handle my DUI case, and does it make a difference?
Yes, the specific courthouse handling your case can make a significant difference. Some courthouses have stricter judges, especially when it comes to DUI cases. As of October 2024, the Harbor Justice Center is known for having a particularly tough stance on DUIs, especially under the jurisdiction of Judge Amit, who tends to impose harsher penalties. Additionally, the Santa Ana courthouse is another challenging venue for DUI cases, particularly for repeat offenders. It often requires more effort to avoid jail time in these courthouses.
Can I refuse a breathalyzer or field sobriety test during a DUI stop in California?
In California, you generally have the right to refuse both a breathalyzer and field sobriety test if you are over 21 and not on probation. However, it’s crucial to understand that this applies to pre-arrest testing. Once you are arrested, California law requires you to submit to a chemical test (either breath or blood), and refusing this test can result in a license suspension. To navigate this, some recommend refusing the preliminary tests and specifically requesting a blood test after arrest. This approach allows you to comply with the law while avoiding the immediate consequences of failing a breath test.
For individuals under 21, refusal is not an option. They are required to take a preliminary alcohol screening test. Similarly, those on probation in California must comply with chemical testing when requested by an officer, even without an arrest.
If I choose a blood test instead of a breathalyzer, can it help my case?
Yes, opting for a blood test can be advantageous. Unlike a breathalyzer, a blood test doesn’t provide immediate results to the officer. This delay can prevent the officer from using your blood alcohol content (BAC) to influence their report or testimony. The officer must rely on their observations without knowing the exact BAC at the time, which can reduce the likelihood of embellishing details. Essentially, it forces the officer to base their report on their observations rather than confirmed BAC levels.
Will my rising blood alcohol level be a valid defense in Orange County courts?
Yes, rising blood alcohol (BAC) levels can be used as a defense in Orange County courts, as well as throughout California. The key legal point here is that it is only illegal to be at or above a 0.08% BAC at the time of driving, not later. If your BAC rises to 0.09% or 0.10% after you have stopped driving, this could support a defense. Jury instructions in DUI cases clarify that the prosecution must prove that your BAC was at or above 0.08% when you were actually driving—not at a later time.
In summary, understanding local courthouse tendencies, your rights regarding tests, and potential defenses like rising BAC can make a significant difference in how you approach a DUI charge in Orange County. It’s always advisable to consult with an experienced attorney to navigate the specific circumstances of your case.
