What Can I Expect If Convicted Of A DWI?

Your punishment and fines for a first conviction depend upon a few factors that can escalate your punishment and fines. Depending upon your blood or breath alcohol level (BAC), you could be charged with a class A or B misdemeanor.

If your BAC less than .15, you’ll be charged with a class B misdemeanor and face:

> the possibility of a fine no more than $2,000 and/or

> 3 to 180 days in jail and

> a suspended driver license from 90 to 365 days

Those penalties escalate if your BAC is .15 or more. Now you’ll face a class A  misdemeanor, which incurs:

> a fine not to exceed $4,000 and

> up to 1 year in the county jail.

Let’s say you have an open container in your vehicle when you are arrested. If you are convicted, the punishment increases requiring:

> a minimum jail sentence of 6 days (instead of 3 days).

> you’ll be assessed an annual tax (called a surcharge) of $1,000-$2,000 by the Texas Department of Public Safety (DPS) to retain your driver’s license.

Your bond condition on a first-offense DWI it entirely up to the court. But, if you are charged with a subsequent offense of DWI or a first offense of intoxicated assault or manslaughter in Texas, you must install a vehicle ignition interlock device on your car. Also, any motor vehicle you operate must be equipped with an interlock device. This interlock device detects a certain level of alcohol on your breath and temporarily disables the vehicle if that level is detected.

2017 DWI Non-Disclosure Law Provides a Second Chance to First-Time Offenders

In 2017, a law was signed allowing first-time DWI offenders with a BAC of .08 to .14 to apply for a “non-disclosure.” If you agree to install an ignition interlock device on your vehicle, the provision restricts who can see your criminal record.. You can apply for a non-disclosure two years after the end of your probation, but you must have an ignition interlock device on your vehicle for 6 months during the non-disclosure period. If you decide not to have the device installed, you must wait 5 years after your probation to apply.

What if I’m convicted of DWI a second time?

The lawyers at Trichter & LeGrand advocate that you fight aggressively if you are charged with DWI the first time because the penalties for subsequent DWI convictions are so severe. If you are charged for a Second Offense DWI, you’ll face:

> a maximum fine increases up to $4,000.00 and/or

> jail from 30 days to one year, and

> a possible driver’s license suspension ranging from 180 days to 2 years (Class A Misdemeanor)

What if I’m convicted of DWI a third time?

If you are convicted of a DWI for the third time, you’ll face a third-degree felony and the penalties and fines become much more severe. You may receive

> a fine up to $10,000.00 and/or

> 2 to 10 years of imprisonment (keep in mind that imprisonment is in a state-run penal institution whereas jail is a county-run institution)

> suspension of your driver’s license from 180 days to 2 years.

> With your felony conviction, you’ll be disqualified from voting and possessing a firearm

Being charged with DWI is life-altering. If you are faced with DWI charges–whether it’s your first, second, third or more–get the help you need and call the attorneys at Trichter & LeGrand to fight for your rights.
