How Narrow California IID Exemptions Are
Many drivers hope to avoid an interlock device after a DUI. However, California IID exemptions are narrow. The main statute lists specific facts a person must certify.
Other rules address work vehicles in separate provisions. So the right answer depends on the vehicle and the job.
The No Vehicle Certification
Vehicle Code section 23575.3 lets a person delay the device requirement until they buy or gain access to a vehicle. To use this, the person must certify facts to the DMV within 30 days of notice. Those facts include not owning a vehicle and not having access to one at home.
The person must also confirm they no longer have access to the vehicle driven at the time of arrest. In addition, they must acknowledge that they may drive only vehicles with a certified device.
Limits of That Rule
The no vehicle rule does not erase the requirement. Instead, it pauses it until access changes. So buying or borrowing a car later brings the device rule back.
Also, the statute defines operating to include vehicles the person does not own. Therefore, borrowing a friend’s car without a device would break the rule.
California IID Exemptions and Work Vehicles
Work vehicles raise separate questions. The Vehicle Code has a provision on employer owned vehicles used during work, and it carries its own conditions. A lawyer or the DMV can explain whether it fits a specific job.
Commercial drivers face added rules. The DMV commercial driver license page covers CDL rules, and the article on California CDL DUI cases explains how a DUI affects commercial driving.
Motorcycles
Section 23575.3 says a person under an interlock restriction may not ride a motorcycle until the state certifies a device for motorcycles. So a motorcycle does not offer a way around the rule. Plan transportation with that limit in mind.
Asking About California IID Exemptions
Ask the DMV which certification form applies and the deadline. Also keep a copy of everything submitted. The DMV DUI page explains interlock and restriction options.
The guide on California DUI IID requirements explains the terms. Meanwhile, the article on transportation after DUI lists other ways to get around.
Some people also ask whether hardship rules create California IID exemptions. The statute text does not list a general hardship exception. Instead, it offers the income based fee schedule to reduce costs.
So people who struggle with costs should ask the installer about that schedule. In addition, a lawyer can explain whether any other provision applies.
