A field sobriety test is not a blood test. It is not a breath machine either. It is one officer standing on the side of the road. That officer decides, right then, if your balance and your eyes look like proof of drinking too much. That single call may be the reason a DWI arrest happens in the first place.
What you need to know is simple. Can that decision be challenged? And what happens to your license and your record if it cannot?
Troy Broussard is a St. John the Baptist field sobriety lawyer who holds the same NHTSA certification Louisiana officers use to score that test. That means our office can walk through your stop step-by-step.
A test that looked convincing on the roadside may not hold up in front of a judge. Reach out and walk us through what the officer had you do. We will review your rights and legal options with you.

Louisiana defines driving a vehicle while impaired in La. R.S. §14:98.
A field sobriety test may be the first piece of evidence an officer points to when deciding whether to make an arrest.
A first offense conviction carries a license suspension of one year. That suspension runs two years if your blood alcohol level was 0.15 percent or higher. You may also face a fine between $300 and $1,000 and up to six months in jail. A conviction can follow you into background checks and professional licensing boards for years after the case closes.
Many people arrested in LaPlace, Reserve, or Garyville commute across the river bridge into Jefferson Parish or New Orleans for work. A suspended license can cost a job before the case is even decided.
This information reflects Louisiana law as of September 2026.
A field sobriety stop can turn into several different charges. It depends on what the officer says he saw and what the chemical test shows afterward. Our attorneys handle the full range of cases that start with a roadside stop in St. John Parish, including:
A field sobriety test is a judgment call. It just wears the costume of a scientific result. The officer decides how to score your balance, your footing, and your eye movement, often on uneven grass or gravel along River Road or Airline Highway, in headlights instead of steady light. Fatigue, nerves, a bad knee, or the wrong shoes can look just like impairment to an officer scoring it on the spot.
Troy Broussard is a certified operator of the same NHTSA-approved field sobriety tests Louisiana officers use. He completed the National College for DUI Defense’s intensive training program at Harvard Law School, built entirely around the science behind both tests, and has attended six of the National College’s summer sessions over the years.
When we take apart how your test was scored, we are working from the same protocol the officer was supposed to follow. We are not guessing at it.
It depends on where in the parish your case starts. West bank matters, including cases out of Edgard and Wallace, are handled at the Edgard Courthouse on Highway 18. East bank matters, including cases out of LaPlace, Reserve, and Garyville, are handled at the East Bank Courthouse Annex, the Arcuri Center, at 1020 Cambridge Drive in LaPlace. Both sides fall under the 40th Judicial District Court, and we appear in both.
Yes. The Sheriff’s Office has run sobriety checkpoints along US 61 and other parish corridors, often working with Louisiana State Police. A stop that begins at a checkpoint follows different rules than a routine traffic stop.
Only 30 days from the date of arrest under La. R.S. §32:667. Louisiana’s implied consent law starts that clock the moment you refuse a breath test or fail one. It runs whether or not you are ever convicted in the criminal case. Missing it means the suspension takes effect automatically.
A failed roadside test is the officer’s opinion. It is not a scientific measurement, and opinions can be wrong. We review how the test was given, where it was given, and whether the officer followed the training required to score it fairly. Then we decide what it proves.
You are not required to have one, but the first appearance is often where plea offers and bond conditions get set. Having a lawyer who already knows how field sobriety evidence holds up gives you a stronger starting position than facing that hearing alone.
A field sobriety test is one piece of evidence. It is not a verdict, and it can be picked apart by someone who knows how the test is supposed to work.

We will walk through how your stop happened, what the test showed, and where your defense starts from there.
