Where to start
- If you were arrested in the last two weeks, start with the deadline checker. The license deadlines move faster than the criminal case.
- If you want to know how serious your case is, run the case evaluator.
- If you are choosing a lawyer, read the questions page before you call anyone, including us.
What this is not. This is general information about New York law, not legal advice or a prediction. It can’t see your video, your paperwork or the breath instrument’s records, and those decide cases. Nothing you enter is sent anywhere; it stays in your browser.

These tools are not a lawyer. We work to keep the numbers and the law on these pages accurate and up to date, but laws, fines and DMV rules change, and some information here may be incorrect or out of date. The results are general information, not legal advice, and using these tools does not create an attorney-client relationship. Always contact a lawyer to confirm the answers and how the law applies to your case. Call or text (516) 939-1529, 24/7.
