What Evidence Might The Prosecution Use?

Blood Testing

Harris County has a no refusal program. A majority of Harris County DWI cases involve blood testing. You need a Houston criminal defense lawyer that is ready to combat this evidence.

Breath Testing

Law enforcement officers also administer a breath test when a driver is suspected of driving while intoxicated. You need a Houston criminal defense lawyer that is ready to combat the deficiencies in the government’s evidence.

Standardized Field Sobriety Tests

Most law enforcement officers conduct side of the road standardized field sobriety tests on drivers to determine if they are intoxicated. Most cases hinge on these roadside tests. You need a Houston criminal defense lawyer who can explain and show a jury just how difficult those tests can be.

What Are The Possible Outcomes of A DWI Charge?

There are multiple outcomes to a criminal case. Our goal at Johnson Garcia LLP is to defend your rights to the fullest to achieve the best possible results.
Jury Trial

Every American has the right to a trial. This is a discussion we will have.


A Class B Misdemeanor probation typically ranges from 1-2 years, depending on the facts of the case and criminal history. Conditions are negotiated with and are set by the District Attorney’s Office. A plea to probation will result in a conviction which will remain on your record.

Jail Time

DWI offenses carry a range of punishment classifications. A Class B first time DWI carries a range of punishment from 1-180 days in county jail. An offer of jail time is negotiated by your attorney with the District Attorney’s Office. In considering a recommendation the assigned Assistant District Attorney will consider facts of your case and your prior criminal record. A plea to jail time will result in a conviction which will remain on your record.

Pre-Trial Intervention

A Pre-Trial Intervention is Harris County District Attorney’s Office program that allows for the defendant to avoid a final conviction while being placed on supervision for a period of time. Clients do not need to plead guilty, and there is no finding of guilt. Upon completion of a set supervised period of time, the case is dismissed without a conviction on your record. Successfully completing a Pre-Trial Diversion will NOT result in a conviction and it will NOT become a part of your criminal record.


A case may be dismissed by the District Attorney’s Office for various reasons. You need an experienced Houston criminal defense attorney to defend your rights and be your voice in court.
