Seeing those flashing lights and orange cones ahead can make your stomach drop, even if you have not had anything to drink. During my time as an Assistant Public Defender in Pinellas County, I defended hundreds of people arrested for DUI in St. Petersburg and throughout Pinellas County. Many had no idea what their rights were or how a single decision at that checkpoint could affect their case.
I am writing to provide you with clear, practical guidance on what actually happens at a DUI checkpoint and how to handle the situation. This is not about beating the system. It is about understanding your rights and making informed decisions in a stressful moment.
What DUI Checkpoints Are and Why They Happen
DUI checkpoints – sometimes called DUI roadblocks – are legal in Florida. The U.S. Supreme Court and local appellate courts have ruled that these checkpoints are constitutional as long as they strictly comply with specific guidelines and that Florida law enforcement agencies must meet those standards.
In St. Petersburg and Pinellas County, you will typically see checkpoints in areas with high traffic volume or documented DUI-related incidents. That might be downtown near Central Avenue after the bars close, along the beach corridors during holiday weekends, or on major routes like I-275 and Fourth Street North. Checkpoints are often announced in advance through local media or on the St. Petersburg Police Department and Pinellas County Sheriff’s Office social media pages.
Sometimes, it might not be a checkpoint, but multiple law enforcement agencies from Pinellas County, Florida, working together on a night and saturating the road with DUI cops to be on the lookout – the Sheriff’s Office calls this a DUI Wolfpack.
What Actually Happens When You Are Stopped
When you approach a checkpoint, officers will be directing traffic. They may stop every vehicle or use a neutral pattern, such as stopping every third or fifth car. If you are signaled to stop, you must pull over. Refusing to stop or making an illegal maneuver to avoid the checkpoint will almost certainly result in a traffic stop.
Once you stop, an officer will approach your vehicle. The officer is making observations from the second they reach your window. They are looking at your eyes, listening to your speech, and watching how you move. They are checking for the smell of alcohol, the smell of marijuana, drug paraphernalia, open containers, or anything else that might suggest impairment.
The officer will ask you for your driver’s license, vehicle registration, and proof of insurance. You are legally required to provide these documents. Have them ready, so you are not fumbling around, which can make you appear nervous or disoriented.
After you hand over your documents, the officer may ask you questions. This is where many people make their first mistake. They feel obligated to answer every question and end up providing information that gets used against them in court.
Your Rights and Your Obligations
While you generally have a right to remain silent and against self-incrimination, a driver lawfully pulled over for a DUI, or in a DUI checkpoint, is under a legal obligation to respond to an officer’s requests for certain information and documents. Failure to do so could put the driver at risk of violating a different statute for obstructing or resisting law enforcement.
You should be respectful and calm. There is a difference between exercising your rights and being confrontational. You can decline to answer questions without being rude.
However, you do not need to volunteer everything. That means you do not have to answer questions about where you are coming from, where you are going, or if you have been drinking. You can politely decline to answer those questions. I have seen cases where a simple “I would prefer not to answer questions” would have changed the outcome entirely. Any admissions you make, such as having a couple of beers at a bar in Downtown St. Pete, will make their way into the officer’s report.
If the officer believes they see signs of impairment, they may ask you to step out and perform field sobriety tests. These are the physical tests you have probably seen: walking in a straight line, standing on one leg, or following a pen with your eyes. You are not legally required to take these tests. They are voluntary.
In my experience as a criminal defense attorney in St. Petersburg, field sobriety tests are often used as evidence against you, and they are subjective. Even sober people can struggle with balance tests on the side of the road at night under stress. You can refuse the tests, but if you do, the officer may still arrest you based on other observations, and you will not have given them additional evidence.
The breathalyzer, or other chemical tests, are different. Florida has an implied consent law, which means that by driving on Florida roads, you have already agreed to submit to a chemical test if you are arrested for DUI. If you refuse a breath or other chemical test after your arrest for a DUI in St. Pete, there will be two types of consequences. For a first refusal, your license will be automatically suspended for one year, and you will likely be arrested and charged for an additional second-degree misdemeanor for refusal. For a second or subsequent refusal, your license will be automatically suspended for 18 months, and you will likely be arrested and charged with an additional first-degree misdemeanor. A refusal can also be used against you in court in front of the jury.
Common DUI Checkpoint Mistakes I Have Seen
The biggest mistake people make is talking too much. They think that if they explain themselves, the officer will let them go. That almost never happens. I have reviewed countless police reports where the person admitted to drinking “a couple of beers.” Those statements go directly into the report and get used against them at trial. How you sound will also likely be captured on body-worn camera footage and be used against you at trial.
Another mistake is trying to avoid the checkpoint illegally. If you see a checkpoint ahead and you can legally turn onto a side street without breaking any traffic laws, you are allowed to do that. But if you make an illegal U-turn or drive over a median, the officer can pull you over for that violation.
I have also seen people refuse to provide their license and registration. That is not exercising your rights. You must provide your documents and be respectful. You can still protect your rights within that framework.
What Happens If You Are Arrested
If the officer believes they have probable cause that you are driving under the influence, you will be arrested and transported to the Pinellas County Jail. At the jail, you will be asked to submit to a breath test. After the breath test, you will be booked. Depending on the time of day, you may be held for several hours before you see a judge for your first appearance.
This is when you need to call an attorney. Do not wait. DUI cases that start at checkpoints are different from regular traffic stops because the legal issues surrounding the checkpoint itself can sometimes be challenged. An attorney who knows the Pinellas County court system can identify problems with how the checkpoint was conducted and how the evidence was collected.
You need someone who knows how critical it is to act quickly. Evidence can be lost, and procedural deadlines can pass. The sooner you have someone working on your case, the better. You will also want to find a lawyer who can help you with the administrative side of applying for a hardship license.
The Balance You Need to Strike
The goal at a DUI checkpoint (or any DUI stop) is not to win an argument with the officer. The goal is to protect yourself legally without making the situation worse. That means being polite, providing the required documents, and exercising your rights calmly.
If you are arrested, call an attorney as soon as you can. If you are unsure about how to choose the right attorney, look for someone with local experience who understands the courts, the prosecutors, and the procedures specific to Pinellas County.
I know what officers are looking for, I know what prosecutors focus on, and I know what defenses work in St. Petersburg courtrooms. If you or someone you care about has been stopped at a checkpoint and needs guidance, reach out to me. I am here to help.
Frequently Asked Questions
Can you legally turn around before reaching a DUI checkpoint in St. Petersburg?
Yes, as long as you do so legally. If you make an illegal U-turn or violate any traffic law while avoiding the checkpoint, an officer can stop you for that violation. If you can safely and legally turn onto a side street or into a parking lot, you may do so.
What happens if you refuse a breathalyzer test at a checkpoint in Pinellas County?
If you refuse a breath test after being arrested for DUI, your driver’s license will be automatically suspended for one year for a first refusal and 18 months for a second refusal. The refusal can also be used as evidence against you in court. You will also be criminally charged for a refusal, and the potential penalty depends on whether it is a first refusal.
Are DUI checkpoints announced in advance in St. Petersburg?
In most cases, yes. Law enforcement agencies in Florida are generally required to announce the time and general location of DUI checkpoints in advance through local news outlets or social media.
Can a DUI checkpoint stop be challenged in court?
Yes, in some cases. If the checkpoint was not conducted according to legal guidelines or if your rights were violated, an attorney may be able to challenge the legality of the stop and the evidence that was gathered. This is why having an attorney with local experience is important.
