Car breathalyzer systems, also known as ignition interlock devices (IIDs), help prevent individuals with a history of DWI from operating a vehicle while under the influence of alcohol. In North Carolina, their use is legally mandated for certain DWI offenders.
These systems require the driver to provide a breath sample before the engine can start. If the sample exceeds a preset blood alcohol concentration (BAC) limit, the vehicle will not start.
The Role of Car Breathalyzers in DWI Prevention
Driving While Impaired (DWI) in North Carolina is a serious offense with significant legal consequences. According to N.C. Gen. Stat. § 20-138.1, it is illegal to drive a vehicle in any public street, highway, or public vehicular area within the state while under the influence of an impairing substance.
This includes not only alcohol but also other drugs and controlled substances (even prescribed ones). The legal limit for blood alcohol concentration (BAC) is 0.08% for most drivers but lower for commercial drivers and minors.
The consequences of a DWI conviction in North Carolina can be severe. They include the following:
- Immediate license revocation or suspension
- Hefty court fines
- Increased insurance rates
- Imprisonment: jail or prison time
- Loss of Professional Licenses
- Ignition Interlock Device Installed
The severity of these penalties typically escalates with subsequent offenses, leading courts and individuals to look for solutions to prevent future DWIs.
The Role of Car Breathalyzers in DWI Prevention
Car breathalyzers, or ignition interlock devices, are increasingly being recognized as a vital tool in the fight against DWI. These devices require the driver to take a breathalyzer test before starting the vehicle.
If the device detects alcohol, the vehicle will not start. This immediate consequence not only prevents drunk driving at the moment but also serves as a constant reminder and deterrent for those with a history of DWI.
An ignition interlock device contributes to a decrease in repeat offenses by requiring a breath sample before the vehicle can start.
Legal Mandates for Car Breathalyzers in North Carolina
In North Carolina, the use of ignition interlock devices is not just a preventive measure but also a legal requirement in certain situations.
Under N.C. Gen. Stat. § 20-17.8, individuals convicted of DWI with a BAC of 0.15% or higher, or those with multiple DWI convictions, legally must install an ignition interlock device in their vehicles.
After your license is restored, you may be required to have an Ignition Interlock installed for the following time periods:
- 1 year if the license revocation was for 1 year
- 3 years if the license revocation was for 4 years
- 7 years if the license was permanently revoked but can be restored (“)
Considering an Ignition Interlock Device Install On Your Vehicle’s Ignition System
If you struggle with drinking and driving, you may look into an interlock device for yourself. While handheld breathalyzers are on the market and easily purchased online, they are easily disregarded after one too many drinks.
If you’re facing DWI charges for a first offense, you may be considering solutions to prevent ever getting a DWI again.
As a first-time offender there is generally not a legal mandate to install an interlock device. However, it’s possible that this intervention could help you to avoid driving while impaired. Research indicates that ignition interlock devices are effective in reducing repeat DWI offenses.
According to the CDC, these devices can decrease recidivism among both first-time and repeat DWI offenders by approximately 70%. This significant reduction highlights the potential of car breathalyzers to help you refrain from driving while impaired.
However, an ignition interlock device doesn’t prevent damage to your health and well-being.
Exploring other measures, such as educational or rehabilitation programs, can provide a more holistic approach to reducing DWI incidents.
