Basic DUI/DWI Requirements
A person is considered legally intoxicated when their blood alcohol concentration (BAC) reaches .08%, as specified by the Texas Department of Transportation (TXDOT). A driver who gives a breath or blood sample that indicates a BAC of .08% or higher can be arrested for driving while intoxicated (DWI).
If you’re wondering what the difference is between a DUI and DWI in Texas, you’re not alone. You may hear these terms used interchangeably, but they refer to different violations in Texas. In the simplest terms, the difference between DWI and DUI in Texas boils down to age. Only drivers who are too young to legally drink alcohol can be charged with DUI.
License Reinstatement
Starting the journey to restore your Texas driver’s license after a DUI or DWI? First, know that the State of Texas will suspend your license for anywhere from 90 days to 2 years, depending on the facts of your case (such as blood alcohol content and whether it’s your first offense.)
To have your license reinstated, you may be required to fulfill some or all of these conditions, as described by the Texas Department of Public Safety:
- Installing an Ignition Interlock Device (IID) on any vehicles you drive
- Completing an alcohol education course
- Paying fees to the state
- Obtaining and maintaining SR-22 high-risk insurance from an auto insurer
- Serving jail time
Check the Texas Department of Public Safety’s license eligibility portal to find out if you qualify for a reinstated license. When you’re ready to have your license reinstated, you’ll need to submit the required paperwork and fees to the Texas Department of Public Safety.
You may also be eligible to apply for an Occupational Driver’s License, which allows you to drive to work, school, or family commitments while your license is suspended. You can learn more on the Texas Occupational Driver’s License information page.

What is an Ignition Interlock Device (IID)?
An Ignition Interlock Device (IID), also called a car breathalyzer, is a device that measures breath alcohol content (BrAC). It is typically installed in your vehicle as part of an administrative or legal requirement after drunk driving. Learn more about Smart Start's Ignition Interlock here.
How do I know if Smart Start’s devices are compliant with my program?
Smart Start’s Ignition Interlock Devices adhere to all the guidelines set by the National Highway Traffic Safety Administration (NHTSA) and the Texas Department of Public Safety (DPS). Smart Start is also on the approved Ignition Interlock vendors list for the state of Texas.
Is an Ignition Interlock Device mandatory for all DUI convictions in Texas?
In Texas, the Ignition Interlock Device requirements depend on the specifics of the DUI conviction. For certain offenses, the court may mandate the installation of an IID.
What if I have a requirement, but I don’t own a vehicle?
In Texas, if you have an Ignition Interlock Device (IID) requirement, but you don’t own a vehicle, you will need to consult with your probation officer or attorney to determine your next steps.
Do I need the device on all of my vehicles?
In the state of Texas, the judge will determine on how many of your vehicles you are required to install the Ignition Interlock Device on.
How do I know if I need a camera/GPS/etc.?
In the state of Texas, your judge or your State authority will specify what you need in addition to your Ignition Interlock Device (IID). In some counties in Texas, cameras are required.
Does the camera watch me all the time?
No, the camera will only take a picture as you provide a breath sample for the device. There is no live video feed.
What happens after I get my DWI?
In Texas, after you get a DWI, you will have a court date. You will be ordered either by a judge or a court to install an Ignition Interlock Device (IID) based on your condition—pre-trial bond, probation, etc.
How do the consequences differ for a first and second DUI? Third? Fourth?
In Texas, the consequences for DUI offenses escalate with each subsequent conviction. Each case varies based on the specifics of the offense, including the driver’s BAC level, whether any property damage or injuries occurred, and other factors. Legal counsel should be sought for personalized advice from a Texas DUI Lawyer or criminal defense attorney.
- First DUI Offense: Penalties can include a fine, jail time, and license suspension. The severity depends on specific circumstances such as BAC levels.
- Second DUI Offense: Increased fines, longer jail time, and extended license suspension periods are common. This reflects the state’s escalating response to repeat offenses.
- Third DUI Offense: This is considered a serious offense and can lead to significant fines, lengthy jail sentences, and a prolonged or indefinite license suspension.
- Fourth and Subsequent Offenses: These are treated with utmost severity, often resulting in the highest level of penalties permissible under law, which can include long-term jail sentences, license revocation and heavy fines.
What happens if I fail a breath test on the Ignition Interlock Device?
In the state of Texas, if you fail a test, your Ignition Interlock Device (IID) will go into a 2-minute lockout before asking you to re-test. If you fail your re-test, the IID will go into lockout again. This process continues until you are able to pass a test. HOWEVER, you will be forced to endure any consequences specified by your State authority if you register a violation. If you exceed the allowed number of violations within a service term, you will enter into a countdown period, during which you must have your Ignition Interlock Device serviced, or you will be locked out of your vehicle completely. If you go into violation lockout, you will need to either obtain a six-hour unlock code from Smart Start so you can drive to a service center, or you will need to tow your vehicle to the nearest Smart Start service center.
