California DUI Probation and Ignition Interlock Devices

What is an Ignition Interlock Device?

An Ignition Interlock Device (IID) is a breathalyzer installed in vehicles to prevent operation by drivers under the influence of alcohol. These devices are typically about the size of a cell phone and are wired to the vehicle's ignition system.

IID Requirement for California DUI Probation

In California, judges may order the installation of an IID as part of DUI probation. This requirement ensures that drivers do not operate vehicles while intoxicated, reducing the risk of recidivism and protecting public safety.

IID Program Administration

California's IID program is managed by two separate agencies:

• Judicial Program: Managed by the courts, this program applies to DUI convictions where an IID is ordered as part of probation.
• Department of Motor Vehicles (DMV) Program: Conducted statewide, this program applies to administrative suspensions or revocations where an IID is required for license reinstatement.

Impact of IID Restrictions

IID restrictions prohibit individuals from operating vehicles without an IID installed. It is illegal to lease, lend, or borrow vehicles without an IID. Additionally, operating a motorcycle while subject to an IID restriction is prohibited.
