While some places might use the terms interchangeably, in Texas there’s a meaningful legal difference between a DUI and a DWI, which can affect bail cost and release time frame.
If your loved one has been arrested for DUI or DWI in San Antonio, understanding the difference is the first step in knowing how to approach posting bail and what legal steps to take from there.
Understanding DWI in Texas
What Is a DWI Charge?
In Texas, Driving While Intoxicated (DWI) applies to adults driving with a blood alcohol concentration (BAC) of 0.08% or higher, or while impaired by illegal or legal drugs.
Common DWI Scenarios
People commonly get DWIs driving home from bars, parties, or other places where alcohol is consumed. Simple lapses in judgment can lead to first-time DWI offenses.
Habitual drunk drivers may be repeatedly pulled over and charged with DWI.
DWIs are also given when drivers are involved in accidents or cause injuries while driving with a BAC above 0.08%.
Understanding DUI in Texas
What Is a DUI Charge?
A Driving Under the Influence (DUI) charge in Texas applies to people younger than 21 driving with any detectable alcohol in their system.
Key Differences From DWI
- DWI is for adults over 21; DUI applies to people under the legal drinking age
- DWI tends to be a more severe charge; DUI is often (but not always) less severe
- Bail conditions tend to be different.
