Why do people install ignition interlock devices voluntarily?
People voluntarily install ignition interlock devices (IIDs) for several important reasons—often related to safety, responsibility, or legal benefits. While most IIDs are court-ordered after DUI offenses, voluntary installation is increasingly common in both personal and professional contexts.
✅ Reasons People Voluntarily Install Ignition Interlock Devices
1. Preventing Drunk Driving
- Individuals recovering from alcohol misuse may install an IID to hold themselves accountable.
- Helps build trust with family or employers who are concerned about impaired driving.
2. Reinforcing Sobriety During Recovery
- People in alcohol rehabilitation programs may use IIDs as a tool for behavioral support.
- Provides a clear, daily deterrent against relapse when driving.
3. Proving Responsibility After a DUI Arrest (Pre-Conviction)
- Some people install an IID before their court date to demonstrate good faith to the judge.
- This proactive step may result in:
- Reduced penalties
- A shorter suspension period
- Favorable consideration during sentencing
4. Getting a Restricted or Hardship License
- In some states, voluntarily installing an IID can help a driver regain limited driving privileges after a suspension.
- Allows driving to work, school, or medical appointments sooner than without it.
5. Protecting Teen or New Drivers
- Parents may voluntarily install IIDs in vehicles used by their teens to prevent underage drinking and driving.
- Gives parents peace of mind and reinforces safe behavior.
6. Company or Fleet Policy
- Employers may voluntarily install IIDs in company vehicles to:
- Reduce liability
- Ensure compliance with zero-tolerance policies
- Protect assets and employees
7. Insurance Incentives or Legal Protection
- Some insurance providers may offer discounts or support for IID installation.
- In the event of an accident, having an IID may help show that the driver was sober and responsible.
8. Peace of Mind for High-Risk Drivers
- People who take certain medications, have a past alcohol history, or have experienced close calls may choose an IID to feel safer behind the wheel.
