First DUI: What’s at Stake

License & SSS

A test result of 0.08+ or a refusal can trigger a Statutory Summary Suspension beginning on day 46 after arrest. Hearing requests are deadline-driven.

Supervision Path

Many first-time cases explore court supervision based on facts and history. Successful completion avoids a DUI conviction on record.

Penalties & Requirements

Potential outcomes include fines/costs, evaluation and recommended treatment, classes, community service, and case-specific conditions.

Where First-Offense Cases Are Won

Reason for the Stop

Lane use, equipment, or speed basis must be supported by reports and video. Dispatch timestamps and vantage points matter.

SFST & Video

HGN, Walk-and-Turn, and One-Leg Stand require specific instructions and scoring. Video can contradict narratives.

Testing Records

Machine logs, observation periods, chain-of-custody, and medical issues are common pressure points.

First-Offense DUI FAQs

Can a first DUI be reduced or dismissed?
It depends on the facts: the stop, SFST instructions, video, testing protocols, and paperwork. One weak link can change the result.
How soon should I act on the SSS?
Immediately. Hearing timelines are short; missing them can make the suspension harder to challenge.
Will I need an evaluation?
Most courts require an alcohol/drug evaluation before sentencing or certain resolutions. Completing recommended treatment can be part of the outcome.
Can someone appear for me?
Some settings allow an attorney to appear without the defendant; others require personal appearance. This varies by courthouse and stage.
