Choosing a DUI Lawyer in St. Louis

With Missouri’s strict DUI/DWI laws, the question isn’t whether or not you should seek the advice of a DUI lawyer, but which DUI lawyer. St. Louis motorists charged with a DUI have a number of options when it comes to representation, but finding a lawyer that truly represents the best interests of the client can be challenging at times.

The consequences of being convicted of a DUI in Missouri are severe. Having legal counsel that you can trust to represent you will be one of many factors in choosing the right lawyer.

Byrnes Law Firm is different. And, we know that you hear just about every law firm in the St. Louis area say that, but Byrnes Law Firm is truly different in the ways we listen to clients, our qualifications, and the amount of time we devote to each case.

Why You Should Choose Byrnes Law Firm for Your DUI Case

We’re understanding. While driving under the influence of any substance is never something any lawyer would recommend, we are understanding. In many cases, driving under the influence comes about after a temporary lapse in personal judgement, and usually the punishment does not fit the crime. It could be something as simple as having one more drink than you planned, or even the result of a faulty roadside sobriety test. In Missouri, a first-time offender could face up to six months in jail — and that’s just for the first offense. Will your job still be waiting for you when you get out of jail? How will you pay the bills that have been adding up in your absence?

We’re ready to listen. Judges routinely make comments to our clients about the level of service Byrnes Law Firm affords to them. So, it’s not just our clients remarking on the personalized attention we bring to each case, but judges, too. In fact, The Huffington Post ranks having a lawyer that is ready to listen to clients as being one of the top things you should look for when choosing a DUI lawyer. Of course, it is also essential find an attorney that is experienced and qualified to represent your case.

We’re ready to represent you. Byrnes Law Firm has successfully represented thousands of clients facing DUI charges in the St. Charles and St. Louis areas. We are ready to take on your case and provide you the information and representation you can use to successfully defend the charges against you.

Should You Take a Breathalyzer Test?

Unless you feel that you are well below the legal limit, the answer to whether or not you should take a breathalyzer test is always an emphatic “NO.” The best way to refuse a breathalyzer is to declare that you will not submit to a breathalyzer test without an attorney present. At this point you should call Byrnes Law Firm at 636-896-4300. We have someone to answer the phone 24 hours a day, 7 days a week.

Field Sobriety Test St. Louis

What About Field Sobriety Tests?

Again, you should not be subjected to a field sobriety test without an attorney present. Field sobriety tests are designed to make you fail, especially if you have naturally poor balance and coordination, or are nervous while taking the test.

The officer will likely inform you that you will be surrendering your license by refusing to comply, but what the officer will not reveal to you is that refusal to comply is not an admission of guilt, and in many instances, your attorney will be able to work out a deal with the prosecutor (especially if it’s your first offense) that will allow you to keep your driver’s license — something that is especially important for CDL drivers and those who rely on their vehicles to go between work and home.


Byrnes Law Firm understands that many people struggle with the financial burdens their case may have, and likely feel reluctant to even speak with a lawyer about their case, often choosing to go at it alone. This is a mistake, and more often than not, will lead to an unfavorable outcome in your case. When your rights are at risk, you need a strong and experienced lawyer at your side to get you through with the best possible outcome, and the Byrnes Law Firm wants you to know that you can call and consult with them about your case absolutely free. Tell your story, and know your options. You’re in good hands.
