Why We’re Qualified to Recommend Nassau County DWI Lawyers
- Most of those “top lawyer” directories are just paid advertising wearing a trustworthy mask. The marketing companies running Justia, Expertise, Yelp, ThreeBest Rated, Avvo, Super Lawyers, Best Lawyers, FindLaw, and others have never sat at a defense table, never cross-examined an arresting officer, and never watched a client’s future hang in the balance on a single ruling. We have. That’s why our recommendations for the best DWI attorneys on Long Island carry more weight than an algorithm that ranks ads.
- Over our career, we’ve defended dozens and dozens of clients facing DWI charges, alongside nearly a thousand felony, misdemeanor, and violation matters throughout Nassau County, Suffolk County, and the five boroughs of New York City.
- Our private practice is focused squarely on defending the accused across Nassau County and the surrounding Long Island communities.
We’d love the chance to speak with you directly before you sign with anyone, but we also understand that choosing a lawyer is a personal decision, and you deserve options. Our only real goal is ensuring you have the information to choose wisely.
Each of the DWI attorneys below shares our belief that every client deserves a committed, thoughtful defense. That’s why we’re proud to call them some of the best DWI lawyers in Nassau County, Long Island.

FAQs About DWI Lawyers in Nassau County, Long Island
When should you hire a Nassau County DWI Lawyer?
Hire a Nassau County DWI lawyer immediately after your arrest. New York’s DWI penalties are among the toughest in the country. A skilled DWI attorney can identify procedural errors, push back on questionable evidence, negotiate with prosecutors, and work toward a reduction or outright dismissal of your charges.
Do you need to hire a DWI lawyer “near me”?
Proximity isn’t everything, but the lawyer you hire must be licensed to practice in New York. That said, there are real advantages to hiring locally. A Nassau County DWI attorney already knows the prosecutors, the judges, the local court procedures, and the unwritten rules that shape how cases get resolved. That local knowledge often translates directly into better results.
How much does a DUI lawyer cost on Long Island?
One of the first questions that may cross your mind is, “How much will a criminal defense lawyer cost?” The answer to this question can vary depending on a number of factors, including the complexity of the case, the severity of the criminal charges, and the attorney’s experience in criminal law. More complex cases involving serious crimes will require more of your attorney’s time, which means these cases will typically cost more than less serious offenses. Criminal defense attorneys usually charge flat fees for their legal services. Most attorneys charge a flat fee to handle pre-litigation matters and another flat fee if the case goes to hearings or trial.
Can DWIs be dismissed in New York?
In New York, having a DWI dismissed is possible, but it’s not easy. Whether a DWI can be thrown out depends heavily on the specific facts and how strong your defense is. Common dismissal arguments include a lack of probable cause for the traffic stop, improperly administered field sobriety or breath tests, violations of constitutional rights during and after the arrest, and a breakdown in the chain of custody for blood or breath samples. An experienced DWI lawyer knows how to spot these weaknesses and press them hard.
Can a DWI charge be reduced in New York?
Yes, DWI charges can be reduced to lesser offenses in New York. The most common reduction is from a DWI misdemeanor down to a DWAI (traffic infraction), which avoids a permanent criminal record. Whether a reduction is on the table depends on factors like the BAC reading, driving history, and the quality of the prosecution’s evidence. A skilled DWI attorney will negotiate directly with the Nassau County District Attorney’s Office to pursue this outcome.
How did we select the “Best” DWI lawyers in Nassau County, Long Island?
