Breath Tests

There are two different types of breath tests police officers use in Utah: portable breath tests, or PBTs, and Breathalyzer® or Intoxilyzer machines. PBTs are not 100% accurate and the results are not admissible in court. Breathalyzer® or Intoxilyzer aren’t 100% accurate either, but the results can be used in court.

The Intoxilyzer machines used by Utah police utilize light-based instruments to measure the amount of alcohol vapor in your lungs. Once the measurement for alcohol vapor is taken, the machine produces an estimate for how much alcohol must be in your blood to create the amount of alcohol vapor in your lungs.

There are many factors that affect the accuracy of this calculation, such as:

  • Your weight
  • How long you blow into the machine
  • Certain medical conditions, including diabetes and acid reflux
  • Alcohol residue in the mouth
  • Radio waves
  • Incorrect calibration of the Intoxilyzer machine

Even without these factors in play, Intoxilyzer machines have a +/-.005 margin of error. That margin of error is wide enough to result in a false positive. In addition to the many things that could affect test results, there are certain procedures that must be followed. Before administering an Intoxilyzer test, Utah police officers must check your mouth to make sure it’s free from alcohol and other debris, and then actively watch you for 15 minutes.

If police officers fail to check your mouth, leave your presence, or fail to take into consideration any other factors mentioned above, you may have an issue to help your case.

This liquor glass and set of car keys should not go together, but if you find yourself taking a DUI blood test in Utah, call Branson West Law!

Blood Tests

Blood tests are considered more accurate and reliable by a court. However, blood tests are only administered if someone is unable or unwilling to take a breath test, and there are even more stringent procedures to be followed.

After blood is drawn, it must be sealed into a vial, labeled, and sent to a lab to be tested. Blood tests can take several weeks or even months to be processed.

If police do not follow the correct procedures for drawing blood, marking the blood, transporting and storing the blood, or testing the blood, the results of the test may be inadmissible in court.

Many individuals wonder if they are able to refuse a breath or blood test. According to the Utah code, your license can be immediately suspended upon refusal to take the test. If you refuse a second time, that suspension can increase to three years.

Cop cars with flashing lights like these are not usually a good sight behind your car - call Branson West Law today for help with your charges.

Implied Consent for Breath or Blood Tests

Utah has an “implied consent” law, which essentially states that by choosing to drive a vehicle in Utah, you consent to being tested for alcohol or drugs when asked by a police officer. It is important to note that for your case, police officers must have had cause to pull you over, and they have to inform you of your rights — including the penalty for refusing to submit to a test, should you choose to refuse a chemical test.

Refusing to take a breath or blood test will result in automatic license suspension up to 18 months. If you submit to an Intoxilyzer test and fail, your license would only be suspended for a maximum of four months.

These consequences only pertain to the first offense. Subsequent offenses for DUI would have significantly higher consequences.

In Utah, license suspension is an extra severe consequence. Drivers in many other states who have had their license suspended for drunk driving can obtain a limited or work permit that allows them to drive in certain circumstances. Utah does not allow such permits. If your license is suspended you cannot drive for any reason or you risk facing additional penalties, other than if you elect to an ignition interlock device, as previously stated.

Branson is fantastic at what he does. He’s honest, communicative, articulate, and professional. I couldn’t have found a better attorney. He explained every detail of how things could play out in court and answered any questions I had very quickly. He worked diligently to get my case dismissed and for that I am forever grateful. The court process is intimidating and complex, but he navigates it well and provides detailed insight as to how it works.

Branson West is the best decision I made when hiring a lawyer! I was facing a lot of felony charges so when looking for a lawyer, I was stressed to say the least! From the moment I met Branson he was incredibly helpful, communicating with me often or answering any questions I had!! He truly made me feel like everything was going to be ok, and everything was! I couldn’t have asked for a better outcome!!! He was able to get all charges dismissed! If you’re looking at this review trying to make a decision he truly is a great attorney and a great guy! Good luck!
- L L, Posted July 12th 2024 on google
Excellent counsel ! Immediately! Responded with incredible efficiency and knew how to answer my question and guide me simply and easily!
- Troy Hoffman, Posted April 29th 2024 on google
Branson West is an absolute pro! He fought for 13 months for me on a case that should have been thrown out from the start. He absolutely embarrassed the prosecution by his performance in the court room. He never gave me false hope, and always was very clear about the risks, and I'm incredibly greatful that I trusted his expertise.
- lion-fox tactical, Posted April 25th 2024 on google
He did a good job explaining what was going on and keeping me up to date on everything
- simon owens, Posted April 5th 2024 on google
Branson is very good at what he does. He is extremely professional and has a well-received presence in the courtroom. His communication with me was always immediate and efficient. One of the things I was most impressed with was his ability to separate facts from opinion. Branson played out the possible scenarios of what I was to expect He asked me what MY goals were and what MY best case scenario was. I felt like I was a part of my own case and defense. He got the state to waive jail time. I am happy with the result Branson achieved for me and thankful I chose him as my lawyer.
- Derrick Phillip, Posted March 13th 2024 on google
An excellent experience all around. I have been working with Branson for the past 11 years and I only have good things that I can say. Great in the courtroom, great communication skills, well respected by the judges, and went above and beyond for my case. This guy is great. Definitely recommend him to anyone who needs a criminal defense lawyer.
- Adonis Jameson, Posted March 13th 2024 on google
Branson and his team were great to work with. They helped me understand the complicated legal system and we're always available for questions.
- Conner Fordham, Posted March 5th 2024 on google
I had a great experience working with Branson. He always responded within a business day (usually within minutes/hours) and was courtius and professional at all times. Cost of representation was given to me upfront, and was reasonable. I also feel confident that he found the best possible resolution for my charges.
- Ryan Perez, Posted November 2nd 2023 on google
Great guy! Very professional. Would highly recommend:)
- Shellie, Posted October 13th 2023 on google
Great attorney and very intelligent. Very honest and trustworthy. He called me back literally with in 2 hours of calling his office. I believe him to be very qualified to represent me in the legal matters I was in. I trust him and most attorneys don’t even call you back ,but Mr. West will. Very good man.
- Brian Riley, Posted June 9th 2023 on google
Called Branson and left a message. Within minutes received a text that he was in court and would call later. An hour later he called, gave me great advice, and said he didn't want to charge me for something he felt I could do on my own. I followed his advice and things went pretty much exactly as he had explained. The outcome was better than I dared hope. I would highly recommend Branson West!!!
- Darin Clark, Posted May 24th 2023 on google
Very honest firm, can't say enough positive things about them. This is a law firm I would trust to represent me and my family members to protect our rights.
- Lucas Osborne, Posted March 6th 2023 on google

- J MacNeal, Posted March 2nd 2023 on google
Branson is one of the most kind and loyal attorneys. He gave me great advise on a case. He took the time to answer my phone calls and texts. He really cares for his clients: and getting the best resolutions. I would recommend him to anyone in the Utah area. When you are going through a hard time----he really takes the time to coach you and listen. He is kind and I treats his clients with such good care.
- Emily Chu, Posted March 1st 2023 on google
Branson took care of my case exactly the way I thought it should have been. He and his team aka Hailee were and have been all I could have hoped for. I think I found him after a simple search brought his name up when he was doing an add or promotion. Sometimes things just click and this was one of those times. I would recommend him to anyone. If you find yourself in need of a fighter in your corner Branson is a good choice.
- Todd Macfarlane, Posted February 26th 2023 on google
Thank you man! Very grateful for your hard work.
- Tyrell Denton, Posted February 23rd 2023 on google

- Cassia Leigh, Posted February 23rd 2023 on google
Articulate, friendly and well versed in criminal law. I’m a very anxious person which makes my speech terribly convoluted and even then he understood me perfectly. I’m very thankful for his patience and expertise, and I’m also very satisfied with the outcome.
