Second DWI

A second driving while intoxicated (DWI or DUI) offense can result in serious penalties, including mandatory minimum jail sentences, required driver’s license suspension, possible fines, monthly reporting to a probation officer, a possible criminal record, and/or requirements to file an SR-22 poof of liability insurance for at least two years.

Texas law requires Dallas County courts to order any person who has been convicted of a second DWI within five years of the previous DWI offense to install and maintain a “deep-lung” air device in their car. This is commonly known as an ignition interlock device and requires the driver of a car to blow in the machine before their car will start. If the machine detects any eythal alcohol in their breath, the car will not start. Additionally, the machine will require the driver to blow in the machine while the driver is operating the vehicle to ensure the driver is not drinking while driving.

Warning: If you have refused to submit to chemical testing or failed a blood or breath intoxication test for DWI, you only have 15 days to request an administrative license suspension to get your license back.

Intoxication Defined Under Texas Law

According to Tex. Pen. Code Ann. § 49.01(2), “intoxicated” means not being able to use normal or mental or physical faculties after alcohol consumption, consumption of a controlled substance or drug, or any combination. An individual can also be intoxicated if they have an alcohol concentration of .08 or more.

An individual is considered per se intoxicated if they have an alcohol concentration of .08 or more. This means even if an individual is able to operate a vehicle and their normal faculties are not impaired, if their alcohol concentration is .08 or higher, they can automatically be arrested and charged with a DWI.

Definition of Operating a Motor Vehicle in Dallas

A “motor vehicle” is defined in Texas under Tex. Pen. Code Ann. § 49.01(3) as a mode of transportation for a person or property, except for anything used exclusively on stationary rails or tracks, such as a railroad.

An individual must have actual physical control of a car in order to be considered operating the vehicle. This means the individual must be physically in the vehicle, or close enough to operate it, and have the capability to operate the vehicle, regardless of whether they are actually operating the vehicle at the time of the arrest.

Texas’ Definition of Alcohol Concentration Level

Under Tex. Pen. Code Ann. § 49.01(1), “alcohol concentration” is defined as the number of grams of alcohol per 210 liters of breath, 100 milliliters of blood, or 67 milliliters of urine. Alcohol concentration is also commonly known as breath alcohol concentration, blood alcohol concentration or BAC. Texas’ legal limit is .08.

Most individuals can easily reach this limit after having consumed only a few drinks. Therefore, many people who think they are able to drive in Dallas are still charged with driving while intoxicated offenses because they have reached the legal limit.

For example, if a man in Texas who weighs 160 pounds drinks two drinks in one hour, his BAC is likely around .05, which is three hundredths under the legal limit and a very narrow margin. If this individual uses toothpaste or mouthwash that contains compounds similar to alcohol right before a breath test, his BAC can go over the legal limit.

A woman in Texas who weighs 140 pounds and drinks two drinks in one hour probably has a BAC around .07 – this is very close to the legal limit. If she consumes three drinks in one hour, her BAC is probably around a .11, which is well over the legal limit and will probably result in an arrest for a DWI if she operates a vehicle.

One drink in Texas is usually measured by a 1.5 ounce shot of 80 proof liquor (or 40% alcohol by volume), one 12 ounce beer (or 4.5% alcohol by volume), or one 5 ounce glass of wine (or 12% alcohol by volume).
