There’s no doubt that ignition interlock devices (IID) save lives. These breathalyzer-type devices that attach to a vehicle’s ignition to prevent it from starting if a driver has alcohol on their breath are becoming an increasingly common consequence for even first-time DUI convictions across the country.
California is nearing the end of a pilot program that took effect in 2019. It requires those convicted of a second or subsequent DUI to have an IID installed to drive legally on a restricted license. First-time convictions don’t require an IID unless the offender caused injury or death. The program is set to expire at the end of 2025.
The proposed law would continue and expand expiring IID requirements
That’s why California lawmakers are working to pass legislation that would require an IID for anyone convicted of a DUI – even a first-time offense that didn’t result in any injuries. To be able to drive legally, a person would need an IID in any vehicle they drove.
Some lawmakers have noted that if the bill becomes law, it would be the biggest step California has taken to reduce drunk driving in the past decade. It has so far received widespread support in the state legislature, and it seems to be moving along.
Those behind the legislation and safety organizations like Mothers Against Drunk Driving hope that it will be passed and signed into law by the first of next year so that California won’t be left without any IID requirements – and in fact, will have stronger, more permanent ones.
The cost of IID installation, maintenance and required monitoring can be out of reach for some people. That’s why the bill provides some financial help for those who qualify based on their income.
An IID can be a life saver – not just for those who would otherwise continue to drive after drinking but for others on the road. Nonetheless, it can be costly, inconvenient and embarrassing. That’s why it’s better to be able to avoid a DUI conviction in the first place. A good first step is to get experienced legal guidance.
