DUI Laws in California

DUI and ignition interlock device (IID) regulations vary significantly across the United States, reflecting a patchwork of state-specific approaches to addressing impaired driving. Each state has different criteria for the installation of IIDs for DUI offenders, the duration of IID installation, procedures for IID removal, and penalties for tampering with the device. To ensure compliance with local laws, it is crucial to check with your state officials and continue reading relevant resources on the webpage for the most accurate and up-to-date information.

What to Know
  • If you are arrested for DUI in California and your BAC is .08% or higher, or if you refuse a BAC test, your driver’s license will be immediately confiscated and you will face an administrative suspension. This action is separate from any criminal charges or penalties.
  • You have 10 days from the date of your arrest to request a DMV hearing to contest the suspension. If you fail to request this hearing, your license will be automatically suspended after the 30-day temporary permit period.
  • After serving the suspension period, you may be eligible for a restricted license allowing you to drive for specific purposes, such as work or school. Additionally, for DUI convictions, especially with repeat offenses or high BAC levels, an ignition interlock device (IID) may be required on your vehicle.

Administrative License Revocation (ALR) Procedures

California, like many other states, has adopted Administrative License Revocation (ALR) procedures. This means that if your BAC is measured at .08% or higher, or if you refuse to take a BAC test, your driver’s license will be confiscated immediately. This action leads to an automatic administrative suspension or revocation of your license, independent of any criminal conviction. Even if you are not ultimately charged with a DUI offense, the ALR procedures can still result in a license suspension. The ALR process is separate from the criminal judicial penalties for DUI, which may include additional license suspension, jail time, community service, installation of an ignition interlock device, and mandatory alcohol and drug counseling.

You will receive a 30-day temporary license that allows you to drive while your ALR case is pending. During this 30-day period, you can request an administrative hearing to contest the suspension. This hearing will be conducted by a DMV administrative hearing officer. If you do not request a hearing within the 10-day window from the date of your suspension notice, your license will be automatically suspended on the 31st day for a period of 4 months. After this suspension period, you may be eligible for a restricted license which allows driving for essential purposes such as work, school, medical appointments, and other court-approved activities.

It is crucial to remember that the ALR process is distinct from the criminal DUI case, involving different authorities and procedures. Prompt action is necessary if you wish to challenge the ALR suspension effectively.

Judicial Procedures

In California, driving with a BAC of .08% or higher is illegal. If convicted of a DUI offense, courts are mandated to impose an ignition interlock device on the vehicle of any driver with a BAC of .08% or higher, regardless of whether it is their first offense.

California IID Update

From January 1, 2019, till December 31st, 2025 SB1046 requires an ignition interlock to be installed immediately after a DUI. SB1046 eliminates the time a person must have a suspended license before he or she can apply for a restricted license —a driver can apply for a restricted license before conviction after installing an interlock and meeting other requirements without completing their license suspension or revocation period.
