If you live or drive in San Antonio, you’ve probably heard plenty of rules about DWI laws, including what police can do, what penalties apply, and how easy it is to beat a charge. Unfortunately, much of what people believe about Texas DWI laws is outdated or incorrect.
In 2025, Texas has continued to tighten enforcement and increase penalties, especially in urban areas like Bexar County. Misunderstanding the law can lead to serious consequences, including license suspension, jail time, and long-term damage to your record.
Below, we break down five of the most common myths about Texas DWI laws in 2025, explain what’s actually true, and show why getting accurate legal guidance matters, especially if your case ends up at the Bexar County Courthouse.
Myth #1: You’re Only Drunk Driving If Your BAC Is Over 0.08%
You can be arrested and charged with DWI in Texas even if your blood alcohol concentration (BAC) is below 0.08%. Under Texas Penal Code Chapter 49, a driver commits DWI if they are operating a motor vehicle while “intoxicated,” which means lacking the normal use of mental or physical faculties due to alcohol, drugs, or a combination of substances. What this means in practice:
- An officer from the San Antonio Police Department (SAPD) does not need a breath or blood test to make an arrest.
- Poor performance on field sobriety tests can be enough.
- Prescription drugs, marijuana, or mixed substances can lead to DWI charges, even with a 0.00 BAC.
In 2025, law enforcement agencies are relying more heavily on officer observations, dashcam footage, and body-worn cameras, making it easier to argue impairment without a numeric BAC.
Myth #2: Refusing a Breath or Blood Test Means There Are No Consequences
Refusing chemical testing can trigger immediate and serious penalties, even before your criminal case is resolved. Texas operates under an implied consent law, meaning that by driving on Texas roads, you’ve already agreed to submit to alcohol or drug testing if lawfully arrested. If you refuse:
- Your driver’s license can be suspended automatically
- You may face a longer suspension than if you had failed the test
- The refusal can be used as evidence against you in court
This is handled separately through an ALR Hearing (Administrative License Revocation), which is a civil process independent of your criminal DWI case. You have only 15 days from the date of arrest to request this hearing. Many San Antonio drivers mistakenly assume refusing “protects” them. In reality, it often makes defending the case more complex and time-sensitive.
Myth #3: First-Time DWI Offenses Aren’t That Serious
A first-time DWI in Texas can still carry jail time, steep fines, and long-term consequences, especially under 2025 enforcement trends. Even a basic first offense may include:
- Up to 180 days in jail
- Fines up to $2,000
- License suspension for up to one year
- Mandatory alcohol education programs
- Increased insurance rates for years
In 2025, prosecutors in Bexar County are taking a tougher stance on “routine” DWIs, particularly when aggravating factors exist, such as:
- High BAC levels
- Accidents or property damage
- Open containers
- Refusal to submit to testing
What many people don’t realize is that a first DWI conviction stays on your record permanently unless successfully challenged or mitigated through experienced legal representation.
Myth #4: DWIs Near Schools Are Treated the Same as Any Other DWI
Certain DWI offenses occurring near schools or involving protected areas can now lead to significantly enhanced penalties in 2025. Texas lawmakers and prosecutors have increased their focus on protecting children and school zones. In recent enforcement changes:
- DWIs occurring in or near active school zones may trigger enhanced charges
- Some offenses can rise to state jail felony level depending on circumstances
- Penalties may include longer incarceration and higher fines
While not every DWI near a school automatically becomes a felony, proximity matters more than ever in 2025, particularly if children are present or school activities are ongoing. If you’re arrested near a school zone in San Antonio, it’s critical to understand how location can impact the severity of charges filed at the Bexar County Courthouse.
Myth #5: No Refusal Weekends Are Just a Scare Tactic
No Refusal Weekends in San Antonio are very real, and they dramatically change how DWI arrests work. During these periods:
- Judges are placed on call to approve blood warrants
- Refusing a breath test often results in a mandatory blood draw
- Law enforcement operates under heightened DWI enforcement protocols
SAPD and Bexar County agencies typically schedule No Refusal Weekends around holidays, major events, and high-traffic weekends. In 2025, these initiatives are more frequent and more coordinated than ever. Many drivers are shocked to learn that refusing a test during a No Refusal Weekend does not prevent chemical evidence from being collected; it simply changes how it’s obtained.
