If you are pulled over, are you required to take a sobriety test? This is something you should know before you are pulled over. It can be a terrifying thing to have those lights appear in your rear view mirror and for the police officer to ask you to get out of your car. It is vital to know what your rights are in advance, so you can act rationally and calmly in the moment. If you have already been charged with a DUI, the first thing you should do is hire a DUI attorney.
Are Sobriety Tests Mandatory?
So, the big question is whether or not you are required to take a sobriety test. This includes the breathalyzer, as well as any other test. This includes blood tests, urine tests, and challenges that test your physical or mental abilities. You may be surprised to learn that you are almost never required to take a sobriety test. There are only three situations where an individual is required to take a sobriety test:
- The individual is under the legal drinking age
- The individual is on probation for a DUI
- The individual has already been arrested.
Let’s go through these one by one. The first is quite simple. If you are younger than the legal drinking age, you must always take a sobriety test if an officer requests you to.
Second, those who have been found guilty of a DUI in the past and are now on probation for this charge must also take a requested sobriety test. This is also a simple concept.
Finally, after you have been arrested, you can be required to take a sobriety test. Remember, you cannot be arrested without probable cause, and a failed sobriety test counts as probable cause. If you do not take the test, it may not be possible for an officer to arrest you.
Should You Take a Sobriety Test?
As you probably suspect, it is never in your best interest to take a sobriety test unless you find yourself in one of the above situations. You may be thinking that a sobriety test can prove your innocence, but this is never the case. It is impossible for a passed test to prove innocence, but a failed test can prove guilt. The test results are also subject to the officer’s interpretation. These facts make it dangerous to take any sobriety test. If you are legally required to take it, however, you should not resist. A DUI attorney can tell you more.

Posted on Google Ashton HTrustindex verifies that the original source of the review is Google. We’ve had an outstanding experience with this firm across multiple needs, including trust document creation and forming an LLC. From start to finish, they were professional and proactive. They made sure we understood every step of the process and checked in to confirm our preferences, as well as offering thoughtful alternatives whenever something didn’t feel like a good fit. That level of communication and attention to detail is rare. Every interaction built confidence that we were in the right hands. They not only handled the legal work effectively, but also made the entire process feel manageable and well-guided. We cannot recommend them highly enough and will absolutely continue using them in the future.Posted on Google Judy sTrustindex verifies that the original source of the review is Google. Attorney Judith Denham and her legal assistant, Gaby Wright, made a great team in creating a trust for me. Judith explained everything in a clear, cohesive way and set up a trust in a timely manner. She gave me a binder for my trust with all the legal paperwork sectioned off in tabs so I can find things easily. When I had questions, Judith and Gaby were responsive and helpful. I give them my highest recommendation.Posted on Google Nancy JTrustindex verifies that the original source of the review is Google.

This website was clear and easy to navigate. It does a good job of explaining services and further supports itself with testimonials.Posted on Google MTrustindex verifies that the original source of the review is Google. I had a few (what I would consider) silly questions to ask the legal team at Patterson Bray PLLC. Having very little knowledge of the situation I needed clarity on, I had no idea what to expect. I was met with nothing but professionalism and warmth from attorney Rachel Meadows. She gave me information I didn’t even remotely consider, and my questions were thoroughly answered without judgement. She could have certainly given me less detailed responses, but I felt that she genuinely cared about my situation, and appreciated her taking me seriously. I’m extremely impressed with the service I received from this law firm and will happily recommend it.Posted on Google Zack CTrustindex verifies that the original source of the review is Google.
