AB1686 amends Vehicle Code Sections 23540 and 23546 to allow DUI convictions that occur within 10 years of one or two prior qualifying DUI-related convictions to be punishable either as a misdemeanor or as a felony. Under current law, that felony-or-misdemeanor exposure already exists for offenders with three or more priors within 10 years; AB1686 shifts that same exposure down to drivers with one or two priors.
The change expands prosecutorial charging options and increases the potential for longer-term consequences for defendants (including collateral consequences tied to felony convictions). It also creates a state-mandated local program by raising penalties, which may increase workload and incarceration costs for counties even though the bill asserts no state reimbursement is required under the California Constitution.
At a Glance
What It Does
The bill modifies Sections 23540 and 23546 of the Vehicle Code so that a DUI occurring within 10 years of one prior qualifying conviction (Section 23540) or within 10 years of two prior qualifying convictions (Section 23546) is punishable either as a misdemeanor or as a felony. Existing statutory fine ranges, license-suspension/revocation mechanics, and minimum county-jail terms remain specified in those sections.
Who It Affects
Prosecutors and public defenders (charging and defense strategy), county jails and courts (case processing and incarceration), the Department of Motor Vehicles (suspension/revocation and license-surrender procedures), and drivers with prior DUI convictions who face heightened criminal exposure and collateral consequences if convicted of a subsequent offense within 10 years.
Why It Matters
The bill broadens felony exposure for a much larger pool of repeat-offender DUIs, changing plea dynamics and potentially increasing incarceration and supervision costs. It also raises practical implementation issues — from proof of prior convictions to coordination between courts and DMV — and could increase disparate impacts tied to prosecutorial discretion.

What This Bill Actually Does
California law currently treats a first DUI conviction as a misdemeanor. For repeat DUIs, penalties escalate: certain repeat offenses within a 10-year lookback period carry enhanced fines, longer jail minimums, and driver-license suspension or revocation.
Today, felony-or-misdemeanor exposure is reserved for drivers with three or more qualifying DUI convictions within 10 years. AB1686 rewrites two specific Vehicle Code provisions so that the same felony-or-misdemeanor exposure applies when a new DUI occurs within 10 years of one prior qualifying conviction (amending §23540) and when it occurs within 10 years of two prior qualifying convictions (amending §23546).
Mechanically, the bill leaves in place the statutory minimum county-jail terms and fine ranges expressed in §23540 and §23546, the DMV’s suspension or revocation authority, the court’s ability to require surrender of a driver’s license, and the restriction device/limited-license procedures the Vehicle Code already contemplates. §23546’s existing three-year habitual-traffic-offender designation for a conviction under that section also remains in the text. What changes is the statutory classification: offenses tied to one or two qualifying priors now fall into the misdemeanor-or-felony bucket, which gives prosecutors the option to seek felony treatment and expands the sentencing universe available to courts if a case is prosecuted as a felony.That shift has practical effects beyond headline classification.
A felony conviction triggers different custody, supervision, and collateral regimes than a misdemeanor: different sentencing frameworks under the Penal Code, possible state-prison exposure depending on charging and plea, and long-term collateral consequences such as limits on firearm rights, housing and employment barriers, and immigration consequences for noncitizens. It also imposes administrative work on the DMV and on courts to process revocations, restricted-license petitions, and the license-surrender requirement tied to these sections.
Finally, because the bill increases criminal penalties it creates a state-mandated local program — counties may face more and costlier cases even though the text asserts that no state reimbursement is required under the state constitution.
The Five Things You Need to Know
Section 23540 is amended so a DUI occurring within 10 years of one prior qualifying conviction may be punished either as a misdemeanor or as a felony.
Section 23546 is amended so a DUI occurring within 10 years of two prior qualifying convictions may be punished either as a misdemeanor or as a felony.
Both sections retain the statutory jail minimums and fine bands currently in the text (e.g.
90–180 days minimums in §23540; 120–180 days in §23546; fines $390–$1,000) and preserve the court’s license-surrender and restricted-license procedures.
A conviction under §23546 continues to carry a three-year habitual traffic offender designation following conviction, with the attendant administrative notifications to the defendant and DMV.
The bill expressly declares that no state reimbursement to local agencies is required because it changes penalties — but it simultaneously creates an unfunded local workload by increasing potential felony prosecutions and related incarceration costs.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
One prior DUI within 10 years now exposes a driver to felony treatment
This amendment takes the existing provision that enhanced penalties apply when a DUI occurs within 10 years of a prior qualifying conviction and adds felony-or-misdemeanor exposure to that one-prior tier. Practically, prosecutors can elect felony charges for a larger class of repeat offenders; courts retain statutory minimum county-jail terms and the authority to require license surrender and to deny a restricted license when they find the defendant poses a safety risk. The change expands the charging envelope without rewriting the fines or the suspension mechanics already set elsewhere in the Vehicle Code.
Two prior DUIs within 10 years also become misdemeanor-or-felony
Section 23546 previously covered offenders with two prior qualifying convictions and prescribed elevated jail minimums, fines, revocation, and a habitual-traffic-offender designation; AB1686 preserves those mechanics but makes a conviction under this section punishable as either a misdemeanor or felony. That adjustment reinforces prosecutorial leverage in mid-tier repeat cases and keeps the three-year habitual-traffic-offender label intact, which has separate licensing and administrative consequences handled by DMV and courts.
No state reimbursement; local fiscal exposure remains
The bill includes the standard constitutional finding that no state reimbursement is required because the act changes penalties. That legal conclusion does not eliminate real local fiscal exposure: counties and courthouses will still absorb any increased costs from additional felony prosecutions, longer pretrial detention, and potentially longer sentences or supervision. The clause matters because it signals lawmakers intend the fiscal burden to rest with local governments, not through a state reimbursement process.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Prosecutors — Gain broader charging discretion and additional leverage in plea negotiations for defendants with one or two prior qualifying DUIs within 10 years.
- Victims and public-safety advocates — Can expect access to felony-level penalties for a wider set of repeat DUI offenders, which proponents argue increases deterrence and accountability.
- DMV and licensing regulators — Their existing authority to suspend, revoke, and process habitual-traffic-offender designations applies to a larger number of cases, giving them clearer statutory grounding for administrative action.
Who Bears the Cost
- Defendants with one or two prior qualifying DUIs — Face increased risk of felony conviction and its lifelong collateral consequences (employment, housing, firearms rights, immigration impacts).
- Public defenders and defense counsel — Will see heavier caseloads and more resource-intensive felony litigation (investigations, motions, jury trials), increasing workload and cost pressures on indigent defense systems.
- Counties, jails, and courts — Likely to absorb greater processing, pretrial, and incarceration costs because felony charges typically require more court time and can lengthen custody periods; the bill’s reimbursement clause does not fund those costs.
- Employers and families of defendants — May face indirect economic and social costs from longer custody or felony convictions for household members (lost wages, childcare disruptions).
Key Issues
The Core Tension
The bill pits a straightforward public-safety objective — enabling harsher criminal treatment for repeat DUI offenders to promote deterrence — against the costs of broader criminalization: increased local fiscal burdens, heavier caseloads for indigent defense, and serious, long-term collateral consequences for defendants; policymakers must weigh whether the safety gains justify expanding felony exposure and the unequal burdens that expansion will likely create.
AB1686 broadens the universe of DUI cases eligible for felony treatment, but the text leaves several implementation and legal questions unresolved. First, the statute adjusts classification without specifying how charging choices will interact with existing Penal Code provisions that govern felony sentencing and state-prison exposure; the practical custody outcome will depend on charging practices and plea bargaining, not solely the amended Vehicle Code language.
Second, the bill assumes reliable proof of qualifying priors within a 10-year window; in practice, establishing out-of-state convictions, old records, or juveniles’ adjudications raises evidentiary and administrative challenges that could complicate prosecutions and defense strategies.
There are also distributional and capacity tensions. Expanding felony exposure risks magnifying racial and socioeconomic disparities tied to prosecutorial discretion and access to quality defense, and could strain county jails, public defender offices, and trial dockets.
Although the bill states no state reimbursement is required, local governments will likely face additional budgetary pressure — an explicit fiscal fix is absent. Finally, the statutory text preserves jail-minimum language even as it authorizes felony treatment, creating potential ambiguity that may invite litigation over whether the legislative changes permit state-prison sentences, how sentencing enhancements apply, and how the amended sections should be read alongside the Penal Code.
