Ignition Interlock Device Laws in Fontana

As with many other states, California enforces admin per se laws that allow the Department of Motor Vehicles to immediately suspend your driver’s license if you fail or refuse a chemical test under suspicion of driving under the influence. The arresting officer will issue an order of suspension and confiscate your license. The DMV will then review the officer’s report and determine if a license suspension would be justified. You also have the right to request a hearing to dispute this administrative suspension.


Administrative penalties are separate from any penalties passed by a criminal court. This means that even if you are found not guilty of a DUI, you are still required to serve the administrative suspension. Your administrative suspension is also often longer for refusing a chemical test than for actually failing it.


Criminal penalties for a guilty DUI conviction in California can vary from case to case. For a first offense DUI without any injuries, deaths, or damage to property, you can generally expect:


  • Up to 6 months of jail time
  • Up to $1,000 in penalty fines (along with court and legal fees)
  • License reinstatement fee of $125
  • Enrollment in a drug and alcohol abuse education program
  • Installation of an ignition interlock device


Second and subsequent offenses will result in more severe penalties, including a higher fines, longer license suspension periods, and more time spent in jail.
