SB 907 rewrites and clarifies the mechanics of Penal Code section 667.5. The bill redraws how prior prison terms are counted, expands the list of crimes treated as "violent felonies," and sets rules for when courts must add extra consecutive prison time for new convictions based on those prior terms.
The change matters to anyone handling cases that can trigger prior‑term enhancements — prosecutors and public defenders, sentencing judges, CDCR intake and release planners, and defense counsel in DUI/vehicular death prosecutions. The revisions tighten prosecutors’ leverage in repeat‑offender cases and create concrete evidentiary and counting rules that will affect plea negotiations and expected custody time.
At a Glance
What It Does
Amends section 667.5 to specify when courts impose additional consecutive prison time tied to prior custodial periods and to identify which crimes qualify as 'violent felonies' for those enhancements. It also clarifies what counts as a prior separate prison term, including out‑of‑state service and certain civil commitments.
Who It Affects
Directly affects defendants with prior custodial history (including out‑of‑state prison time and some civil commitments), prosecutors charging enhancements, defense counsel litigating or negotiating enhancements, and CDCR and county jails that handle sentence computation and custody. Judges will apply new counting rules during sentencing.
Why It Matters
By formalizing which prior terms count and expanding the violent‑felony list, the bill increases sentencing exposure in a swath of cases (notably those involving vehicular deaths). That will shift charging and bargaining dynamics and has downstream effects for prison population and postrelease supervision.

What This Bill Actually Does
The bill centers on three practical categories of change: (1) who qualifies as a repeat violent offender for purposes of extra consecutive time, (2) how to measure and prove prior custodial terms, and (3) limited procedural exceptions. It requires courts to add extra consecutive time for new offenses when the defendant has prior separate prison terms that fall within the statutory definitions — but only under the precise conditions described in the text.
Those conditions include time windows that can wipe out old priors, and categorical rules about the kinds of prior confinement that count.
SB 907 expands the roster of crimes the statute treats as "violent felonies," expressly listing certain driving offenses alongside traditional violent crimes. In practical terms, a conviction for a qualifying new offense can trigger a modifier tied to the defendant’s past prison history; whether that modifier actually applies will depend on whether the prior term meets the statute’s formal criteria and whether it falls within the statute’s specified look‑back period.The bill lays out detailed definitions to guide sentencing courts: what counts as "served" time (state, federal, hospital commitments credited as prison time), how to treat out‑of‑state convictions (only if the defendant actually served one year or more), and when civil commitments or Division of Juvenile Justice confinements are treated as prior prison terms.
It also requires that any enhancement be charged and either admitted by the defendant or found true by the factfinder before the extra time can be added.Finally, SB 907 addresses a narrow—but important—class of cases where the new offense is committed while the defendant is temporarily outside prison (for transfers, furloughs, or community placements). Under the bill, those incidents can be treated as full enhancements unless another law already imposed a full separate consecutive term.
That change closes a procedural gap that previously allowed certain in‑custody offenses to escape prior‑term counting.
The Five Things You Need to Know
The bill requires a three‑year consecutive enhancement for each prior separate prison term when the new offense is one of the statute’s listed 'violent felonies.', It establishes a 10‑year washout: an additional term under the three‑year rule is not imposed for a prior prison term served before a 10‑year period in which the defendant remained free of prison custody and felony convictions.
For non‑violent felonies involving a sexually violent prior, the bill mandates a one‑year consecutive enhancement per prior sexually violent offense and uses a shorter five‑year washout window for those priors.
SB 907 explicitly adds vehicular manslaughter (Pen. Code §191.5 and certain paragraph (c)(1) manslaughter) to the list of 'violent felonies' that can trigger the three‑year enhancement.
Subdivision (k) treats offenses committed while a defendant is temporarily removed from prison (transfers, furloughs, community placements) as fully subject to the section’s enhancements unless another law already provided a full separate consecutive term.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Three‑year enhancement for listed violent felonies
This provision obliges courts to impose an extra three‑year consecutive term for each prior separate prison term when the new offense is one of the violent felonies enumerated in subdivision (c) and the prior was itself one of those violent felonies. Practically, prosecutors who secure proof of qualifying priors can regularly seek these stacked three‑year increments; judges must impose them unless a statutory 'washout' applies. The provision also contains the 10‑year stability limiter: priors served before a decade free of custody and felonies do not trigger the enhancement.
One‑year enhancement for sexually violent priors
Where subdivision (a) does not apply, this section forces a one‑year consecutive term for each prior separate prison term that was for a sexually violent offense as defined in Welfare & Institutions Code §6600(b). The provision includes a five‑year washout tied to remaining free of custody or felony convictions and incorporates county‑jail terms imposed under §1170(h) into the counting regime, meaning some county jail incarcerations may activate this enhancement.
Expanded list of 'violent felonies' (including vehicular manslaughter)
Subdivision (c) enumerates the crimes treated as violent felonies for enhancement purposes. It follows the traditional catalog of homicide, sex, and serious assault offenses and adds offenses such as vehicular manslaughter (listed as item (25)). The practical effect is straightforward: qualifying driving‑related deaths are now within the statutory category that triggers the higher enhancement in (a), increasing sentencing exposure in those prosecutions.
Definitions and counting rules for prior prison terms
These provisions specify when a defendant is “deemed to remain in prison custody,” how a 'prior separate prison term' is calculated, and what forms of confinement count as served prison time. Key mechanical points include counting mandatory supervision and parole periods, treating certain civil commitments (State Hospitals) that exceed one year as prison terms, treating Division of Juvenile Justice confinement as state prison service in some circumstances, and requiring a one‑year minimum served in another jurisdiction for that conviction to qualify as a prior. Those definitions alter record‑checking and proof strategies at sentencing and determine whether an out‑of‑state or nontraditional confinement will increase a sentence.
Offenses during temporary removal, transfer, or furlough
This subsection makes clear that if the new offense occurs while the defendant is temporarily removed from custody (for medical transfer, community placement, or furlough), the full enhancements apply. The clause closes a loophole where in‑custody escapes into temporary programs could have been argued to avoid prior‑term application. It contains an exception: if another law already imposed a full, separate consecutive term, subdivision (k) does not duplicate that sentence.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Victims’ families and survivors — The expanded violent‑felony roster and mandatory enhancements increase the likelihood of longer consecutive terms, providing a clearer legislative signal of condemnation and greater predictability about total sentence length.
- Prosecutors — The bill supplies a firmer statutory basis for seeking stacked enhancements, simplifies charging decisions in cases with qualifying priors, and strengthens leverage in plea negotiations.
- State corrections planners (CDCR) — The statute clarifies which prior terms and commitments count, improving sentence computation and forecasting for prison population management.
Who Bears the Cost
- Defendants with prior prison terms — They face higher statutory minimum exposure when charged with qualifying new offenses, and plea bargaining dynamics will change against them.
- Local governments and the state correctional system — Expect upward pressure on custody time and bed needs because mandatory consecutive terms reduce early release and compression of sentences.
- Defense counsel and public defenders — Their caseloads will include more complex factual disputes about whether priors qualify (proof of out‑of‑state service, civil commitments, juvenile incarcerations), increasing litigation burden and resource needs.
- Courts — Judges must resolve more enhancement proofs at sentencing, and trial resources will be taxed by the need to litigate prior‑term issues that previously might have been handled within plea bargaining.
Key Issues
The Core Tension
The central dilemma is between public safety and proportionality: SB 907 advances predictable, harsher penalties for repeat offenders (including those responsible for vehicular deaths) to reflect societal condemnation and deter recidivism, but it does so by folding crimes with different mental states and policy rationales into a single enhancement regime — increasing the chance that defendants with lower culpability or long‑dormant priors will receive substantially longer sentences.
The bill tightens statutory language in ways that create several implementation questions. First, categorizing vehicular manslaughter as a 'violent felony' raises immediate proportionality and mens rea issues: vehicular manslaughter often involves negligence or gross negligence rather than the deliberate violence typical of other listed offenses.
Treating those convictions as the same class for enhancement purposes will likely change charging strategies and may push more cases to jury trials to contest the factual predicates for enhancements.
Second, the out‑of‑state and civil‑commitment counting rules introduce evidentiary complexity. The provision requiring that an out‑of‑state conviction only qualify if the defendant actually 'served one year or more in prison' will demand certified records, but the statute does not specify acceptable proof formats or how to handle incomplete records.
Similarly, counting civil commitments and Division of Juvenile Justice confinement as prior prison terms raises doctrinal questions about whether indeterminate or therapeutic confinement should carry the same punitive consequences as state prison. Finally, the interaction between the specified washout periods (10 years for violent felonies, 5 years for sexually violent priors) and modern recidivism research creates a policy trade‑off: shorter washouts ease enhancement activation but risk punishing individuals whose risk profiles have meaningfully changed.
