Do I Really Need to Hire an Attorney?

If you are facing DUI or DWI charges in or near San Marcos, Texas, the answer is yes—you need a lawyer now. You may feel certain, beyond a shadow of a doubt, that you face wrongful charges. Or, even if you believe your innocence will require uncovering and exposing certain facts, you may believe that this should be no problem for a public defender to handle. But before you choose not to hire an attorney, consider:

Public Defenders Rarely Have the Bandwidth You Need

It's no secret that public defenders are stretched to their limits—and often beyond—when it comes to their caseload. Trusting your case to a public defender doesn't make your conviction certain, but it will probably make achieving reduced or dropped charges much more unlikely. By hiring the Law Offices of Jason Trumpler to provide counsel, you can rest assured that your case will receive the attention, investigation, and dedication it needs.

Mr. Trumpler Frequently Handles DWI Cases

Jason Trumpler doesn't exclusively provide DWI defense, but DWI cases do account for a significant portion of this Texas lawyer's caseload. And as an attorney who has worked as both a prosecutor and a defender throughout the course of his career spanning more than two decades, he has an intimate knowledge of the tactics both sides use, as well as the first places to look for weak points in the prosecution's case.

There Is Too Much at Stake

Even if this is your first DWI offense, a conviction could result in jail time of up to six months, license suspension of a year, and up to $2,000 in fines. Subsequent offenses have exponentially harsher penalties, with a third offense being punishable by up to a decade in jail and fines of as much as $10,000. With a lawyer like Jason Trumpler on your side, you can avoid incarceration and have the case expunged from your record so that you don't have to carry a constant reminder of this challenging time in your life.

San Marcos and Hays County Can Count on Jason Trumpler A Lawyer Providing Effective Criminal Defense

Hays County Historic Courthouse in San Marcos Texas

Hays County sits between Austin and San Antonio, making Interstate 35 a busy route. Located almost exactly between these cities, San Marcos is home to Texas State University. Many Hays County residents travel to Austin and San Antonio on a regular basis for work and entertainment, and students account for a significant amount of traffic within the county. This places many residents under the scrutiny of both local and state law enforcement on a daily basis.

But just because you are traveling back home from Austin, TX, in the earliest hours of the morning does not mean you are under the influence, and not every student making a late-night drive is making poor choices that place others in danger. Unfortunately, it almost always takes a lawyer to prove this once law enforcement files charges. Fortunately, DWI lawyer Jason Trumpler is always ready to provide criminal defense services to Hays County and communities throughout Central Texas.

DWI Charges Don't Have to Lead to Conviction When You Hire Attorney Jason Trumpler for DWI Defense

Everyone makes mistakes on the job. Unfortunately, when law enforcement personnel make mistakes on the clock, it can change lives for the worse. Because even a charge of DUI or DWI without conviction can carry a damaging stigma, you may believe there is no hope for your case. But rest assured, if the DWI charges against you are unwarranted or allege an extent of criminal activity you did not commit, Jason Trumpler can make these discrepancies clear to a jury. 

Let's say you failed a field sobriety test, breathalyzer, or blood test. Each requires a specific protocol, and none are error-free. Misconduct such as using an improperly calibrated breathalyzer or allowing a blood sample to become contaminated can be uncovered by Mr. Trumpler and used to discredit the prosecution's argument. Similarly, if a condition such as an inner ear infection affects your equilibrium and causes you to fail a field sobriety test, Mr. Trumpler can illustrate this point to a jury.

Another example of a defense strategy relates to the fact that law enforcement must have probable cause to arrest you. That means there must be evidence that would reasonably suggest criminal activity had taken place, such as the smell of alcohol on your breath or open alcohol containers in the car. Although this can be difficult to dispute, Mr. Trumpler will analyze the facts to determine if the arresting officer actually had probable cause to arrest you on charges of DWI.

Can a First-Time DWI Be Sealed? Explore Whether You’re Eligible for Nondisclosure

If this is your first DWI offense in Texas, you may be eligible to avoid conviction by completing a process called deferred adjudication, which involves a probationary period.

Successful completion of deferred adjudication can then make you eligible to file a petition for nondisclosure, which seals your record from public view. You can protect your job prospects, housing status, and personal reputation.

Attorney Jason Trumpler helps clients throughout San Marcos and Hays County navigate this alternative process with confidence and efficiency.
