Ignition Interlock Device Laws in Modesto, CA

Penalties for driving under the influence depend on various factors, including your age, the type of license you have, and any prior DUIs on your record. When you are arrested for a DUI, you may suffer admin per se penalties. These administrative penalties are separate from criminal penalties and are passed directly from the state’s Department of Motor Vehicles.

Admin per se penalties happen immediately when you either refuse or fail a chemical test. The arresting officer confiscates your license and gives you an order of suspension and a temporary license. Your license is sent to the DMV along with the officer’s report. Using this information, the DMV will conduct a review to decide whether to suspend your license. You can request a hearing if you think the suspension is not justified.

Generally, the penalties are more severe if you refuse to take a chemical test than if you fail the test. For refusing a chemical test on your first DUI offense, you may suffer a one-year suspension. A second offense can lead to a license revocation of two years. Third and subsequent offenses can lead to a license revocation of three years.

Outside of admin per se penalties, you can also suffer from criminal penalties if your BAC exceeds the legal limit. For your DUI offense, penalties you may suffer include:

  • $1,000 in fines, along with other fines and court fees
  • $125 fee for reinstating your license
  • Up to 6 months of jail time
  • Installation of an ignition interlock device

Second and subsequent offenses can result in harsher penalties, including longer suspensions and higher fees.

You are required to install an ignition interlock device in any vehicles you own and operate, and you are also responsible for paying for any monitoring and maintenance fees.
