Ignition Interlock Device Laws in San Antonio

Texas has administrative laws that are enforced by the Department of Public Safety. These laws aim to discourage drunk driving while further punishing those who do commit DWIs. Administrative laws allow for the immediate suspension of a driver’s license if they fail or refuse a chemical test administered by an officer of the law. Administrative penalties are an additional punishment to criminal penalties, meaning that you are required to compete them even if you are not found guilty of a DWI in court.

Criminal penalties for a DWI depend on the specific circumstances of your case, including your age, the type of license you own, and any prior DWI offenses. Most penalties for a DWI offense include a combination of:

    • Fines and surcharges (along with any court and legal fees)
    • Community service
    • Jail time (even for first time offenses)
    • License suspensions and revocations
    • DWI education and evaluation programs
  • Higher car insurance premiums

Penalties for a first offense DWI without any injuries, deaths, or damage to property will generally include:

    • Up to $2,000 in fines
    • 3 to 180 days of jail time
    • Up to two years of license suspension
    • Yearly surcharges of $2,000 for three years
    • DWI education and evaluation programs
  • Installation of an ignition interlock device in any vehicles you own and operate
