California Ignition Interlock Devices: What DUI Drivers Need to Know

Understanding Ignition Interlock Devices in California

An Ignition Interlock Device (IID) is a breathalyzer installed in vehicles to prevent operation by drivers under the influence of alcohol. In California, IIDs serve as a measure to curb repeat DUI offenses. The device requires the driver to provide a breath sample before starting the car. If alcohol is detected, the vehicle will not start.

The state mandates IIDs for many, though not all, DUI offenders as a deterrent against future violations. While installing an IID can be costly and inconvenient, it often enables offenders to regain driving privileges sooner. This approach reflects California’s commitment to enhancing road safety and reducing DUI recidivism.

How an Ignition Interlock Device Works

An Ignition Interlock Device (IID) measures the driver’s blood alcohol concentration (BAC). If it detects alcohol, it prevents the vehicle from starting. After a failed test, the IID imposes a lock-out period, which increases after each subsequent failure.

During drives, IIDs require rolling retests. Failing a retest triggers an alarm or the car’s horn, urging the driver to stop the vehicle. The device records information about failed retests but does not stop a moving vehicle for safety reasons.

Tampering with an IID can lead to the revocation of driving privileges and additional criminal charges.

Discretionary Device Laws

Judges in many states have the discretion to mandate IIDs for certain DUI offenders, including first-timers. These devices are often part of the conditions for a restricted license during a portion of the license suspension period.

To drive legally with an IID, offenders typically must fulfill other court-imposed requirements, such as:

  • Serving jail time
  • Completing probation
  • Paying fines
  • Finishing an alcohol treatment program
  • Undergoing a period of complete license suspension

Mandatory IDD Laws in California

In California, certain DUI offenses trigger mandatory Ignition Interlock Device (IID) installation requirements. These laws aim to reduce repeat DUI incidents by ensuring that offenders can only operate their vehicles if they pass a breathalyzer test. Here’s a breakdown of the mandatory IID laws:

  • DUI Convictions: For most DUI convictions, California law requires the installation of an IID for a period ranging from six months to several years, depending on the number of prior offenses and the severity of the incident.
  • First-Time Offenders: Even first-time offenders may be mandated to install an IID, especially if their DUI involved aggravating factors such as a high blood alcohol concentration (BAC) or causing an accident.
  • Repeat Offenders: The requirement becomes stricter with subsequent DUI convictions, with longer mandatory IID installation periods.
  • Conditional License Restoration: Installing an IID is often a condition for restoring driving privileges after a DUI suspension, allowing offenders to drive legally as long as they comply with the IID requirements.

Ignition Interlock Device Installation and Costs

Installing an Ignition Interlock Device (IID) involves specific steps and associated costs. After a DUI conviction requiring an IID, offenders must select a state-approved provider for installation. The process includes:

  • Selection of Provider: Offenders choose from approved IID providers.
  • Installation: A technician installs the IID, integrating it with the vehicle’s ignition system.
  • Costs: Installation fees vary by provider but typically range from $70 to $150. Monthly leasing fees, including maintenance and calibration, can range from $60 to $80.
  • Calibration and Monitoring: Regular calibration checks ensure the IID functions accurately, included in the monthly fee.
  • Duration: The mandated period for having an IID installed varies, influenced by the offense’s specifics.

Offenders bear the financial responsibility for the IID, covering installation, leasing, and maintenance costs.
