Ignition interlock devices.
Summary
(1) Existing law makes it unlawful for a person who is under the influence of any alcoholic beverage, has 0.08 or 0.04 percent or more, by weight, of alcohol in their blood, as specified, is addicted to the use of any drug, is under the influence of any drug, or is under the combined influence of any alcoholic beverage and drug to drive a vehicle. Existing law prohibits a person from driving a vehicle under the influence of any alcoholic beverage or drug and concurrently do an act forbidden by law, or neglect a duty imposed by law in driving the vehicle, which act or neglect proximately causes bodily injury to a person other than the driver. Existing law, until January 1, 2033, requires the Department of Motor Vehicles to immediately suspend or revoke the privilege of a person to operate a motor vehicle upon the receipt of an abstract of the record of a court showing that the person has been convicted of driving a vehicle under the circumstances above as well as for engaging in a motor vehicle speed contest for specified periods of time, depending on the statute under which the driving violation was punished, and prohibits the reinstatement of the driving privilege until the person gives proof of financial responsibility and proof satisfactory to the department of successful completion of a driving-under-the-influence (DUI) program, as specified. Existing law requires the department to advise the person that they may apply for a restricted driver's license if the person meets certain requirements, including, among others, satisfactorily providing proof of enrollment in a certain DUI program and the installment of a functioning, certified ignition interlock device (IID) . Existing law allows, for certain violations, a person who has had their driver's license suspended to apply to the department for a restricted license, subject to certain requirements. For specified violations, existing law requires the department to issue a restricted driver's license if the person has met certain requirements, including proof satisfactory to the department of enrollment in, or completion of, a DUI program, proof of financial responsibility, and the payment of all applicable reinstatement or reissue fees, among other fees, required by the department. This bill, beginning on January 1, 2031, would reorganize and recast the penalties and sanctions for the alcohol- and drug-related driving offenses described above. The bill would recast violations for driving under the influence of any alcoholic beverage or having 0.08 or 0.04 percent or more, by weight of alcohol in blood (collectively "alcohol-related driving violations") from violations for driving under the influence of any drug or driving while a person is addicted to the use of any drug (collectively "drug-related driving violations") . For convictions of alcohol-related driving violations, the bill would require the department to suspend the privilege to operate a motor vehicle and would allow the suspension to be indefinite. The bill would prohibit the reinstatement of that privilege until the person satisfies certain requirements, including, among others, the person applying for and maintaining a restricted driver's license for certain periods of time depending on the statute under which the driving violation is punished, which includes installing a certified IID on each vehicle operated by the person, providing proof satisfactory to the department of successful completion of a DUI program, as specified, paying all applicable reinstatement and reissue fees required by the department, and providing proof of financial responsibility. For convictions of drug-related driving violations described above, this bill would require the department to suspend the privilege to operate a motor vehicle for specified periods of time, depending on the statute under which the violation was punished. The bill would also prohibit the reinstatement of the privilege until the person satisfies certain requirements described above, but the bill would not require the person to install a certified IID or apply for and maintain a restricted driver's license for a specified period of time. This bill, beginning on January 1, 2031, would authorize a person, whose privilege to operate a motor vehicle is suspended for alcohol-related driving violations, to apply for a restricted license if certain requirements are met, including, among others, installing a certified IID on each vehicle operated by the person, as specified, providing proof of financial responsibility for 3 years, providing satisfactorily proof of enrollment in, or completion of, a DUI program, as specified, and paying a fee that is sufficient to cover the costs of administration of these requirements. The bill would require the department to terminate the restricted driver's license and suspend the privilege to drive if the person fails to comply with the DUI program requirements. The bill would also authorize a person, whose driving privilege was suspended for a conviction of a drug-related driving violation, to apply for a restricted driver's license if similar certain requirements are met, except the person would not be required to install a certified IID but would be required to complete a minimum number of months of a suspension period, as specified. This bill, beginning on January 1, 2031, would require the department to monitor the installation and maintenance of an IID that is installed pursuant to specified provisions. The bill would require the installer of the IID to notify the department if the device is removed or indicates that a person has attempted to remove, bypass, or tamper with the device, or the person fails 3 or more times to comply with these requirements. The bill would require the department to immediately suspend or revoke the privilege to operate a motor vehicle and any restricted driver's license if the person attempts to remove, bypass, or tamper with an IID, has the IID removed prior to the termination date of the restriction, or fails 3 or more times to comply with any requirement for the maintenance or calibration of the IID. The bill would require the department, and manufacturers, installers, and repairers of IIDs, to post information regarding filing complaints against manufacturers, installers, and repairers, as specified. (2) Existing law requires an order of suspension of a person's privilege to operate a motor vehicle for any of specified reasons, including the person was driving a motor vehicle when the person had 0.08 percent or more, by weight, of alcohol in their blood. Existing law requires the notice to be served on the person by a peace officer under specified conditions where test results show that the person has specified percentages of alcohol in the person's blood or where a person under 21 years of age refuses to take, or fails to complete, a specified test for alcohol in the blood. This bill, beginning on January 1, 2031, would include a person driving a motor vehicle when a passenger for hire was a passenger in the vehicle and the person had 0.04 percent or more, by weight, of alcohol in their blood as a reason to immediately suspend the privilege to operate a motor vehicle. The bill would authorize a person, whose driving privilege has been suspended pursuant to the provision above but not suspended or revoked based on the person's refusal to submit to, or failure to complete, a chemical test or tests, to apply for a restricted driver's license if certain requirements are met, including completing 30 days of the suspension period, providing proof of enrollment in a DUI program, installing a functioning, certified IID on any vehicle that they operate, being 21 years of age or older at the time of the offense, giving proof of financial responsibility, and paying all reissue and restriction fees. The bill would require the department to terminate the restricted driver's license and suspend the privilege to operate if the person has failed to comply with the DUI program requirements, or if the person attempts to remove, bypass, or tamper with the IID, removes the IID prior to the termination date of the restriction, or fails 3 or more times to comply with any requirement for the maintenance or calibration of the IID. (3) Existing law requires the department to suspend or revoke a person's privilege to operate a motor vehicle based on a peace officer's sworn statement or report, as specified. Existing law requires the department to review the record to determine whether the suspension or revocation is supported by the record, as specified. This bill, beginning on January 1, 2031, would require the department to review these determinations and consider the sworn report and any other information and evidence, as specified. If, by a preponderance of the evidence, the department determines in the review of a determination certain facts are proven, including, among other facts, that the peace officer had reasonable cause to believe that the person had been driving a motor vehicle in violation of an alcohol- or drug-related driving provision, the bill would require the department to sustain the order of suspension or revocation. If the department determines that any of these certain facts are not proven by a preponderance of the evidence, the bill would require the department to rescind the order of suspension or revocation, as specified. (4) Existing law allows, for certain violations, a person who has had their driver's license suspended to apply to the department for a restricted license, subject to certain requirements as provided above. This bill, beginning on January 1, 2031, would authorize a court to disallow the issuance of the restricted driver's license if the court determines that the person would present a traffic safety or public safety risk if the person were authorized to operate a motor vehicle during the period of suspension. This bill, beginning on January 1, 2031, would make conforming changes to include the provisions above, as applicable, in statutes that generally pertain to the suspension, revocation, or restriction of the privilege to operate a motor vehicle. (5) This bill would declare that it is to take effect immediately as an urgency statute.

MINOR
This diff represents the transition from the Senate-amended version (August 18, 2026) to the final enrolled version of AB 1830. The visible changes are primarily structural: removal of multiple amendment history headers and reformatting of the bill text for enrollment. The substantive policy content - a comprehensive overhaul of California's DUI penalty system effective January 1, 2031 - appears unchanged in the portions visible.
TECHNICAL
Removed all Senate amendment history headers (August 18, August 5, and June 15, 2026) from the bill text, which is standard when a bill reaches its final enrolled form.
The bill text was restructured for the final enrolled version. The diff is truncated (showing only 863 of 10,882 lines), so the full scope of formatting changes cannot be assessed, but no substantive policy language changes are visible in the removed portions.
