Understanding What an Ignition Interlock Device Is
An ignition interlock device is a piece of technology installed in a vehicle that helps prevent drunk driving. It functions like a breathalyzer and is connected to the vehicle’s ignition system. Before starting the car, the driver must blow into the device. If the device detects alcohol on the driver’s breath above a preset limit, it will prevent the vehicle from starting. Some devices also require random retests while the car is in operation to ensure the driver remains sober. These devices are highly effective in reducing repeat offenses of drunk driving. They act as a safeguard, ensuring that someone with a history of impaired driving cannot operate a vehicle under the influence. Although the idea of having such a device in your vehicle may feel invasive or embarrassing, it is a common consequence for those facing DWI charges in Texas.When an Ignition Interlock Device Is Required in Texas
In Texas, a court may require an ignition interlock device under specific circumstances. If you are charged with a second or subsequent DWI offense, you are more likely to face this requirement. The court may also order the installation of this device for a first-time DWI offense if your blood alcohol concentration was particularly high or if aggravating factors were present, such as having a child passenger in the vehicle at the time of the arrest. Ignition interlock devices are often mandated as part of the conditions for obtaining an occupational driver’s license. This type of license allows individuals to drive under limited circumstances, such as going to work, school, or medical appointments, while their regular license is suspended due to a DWI conviction.
