AB2015 revises Section 22349 of the California Vehicle Code with a set of drafting fixes: it replaces archaic or mixed phrasing, clarifies that passing lanes do not count as additional through lanes for the 55 mph two‑lane limit, and updates an intent clause to reference signage. The bill does not change the substantive speed ceilings — 65 mph generally and 55 mph on two‑lane undivided highways unless higher speeds are posted — nor does it add new penalties or enforcement tools.
For practitioners, the bill matters because it reduces textual ambiguity that can complicate enforcement decisions, engineering surveys, and judicial interpretation. It also reiterates legislative intent that signage be reasonably provided on affected two‑lane roads, which may influence local and Caltrans signage priorities even though the provision does not appropriate funds or create a new mandate.
At a Glance
What It Does
AB2015 performs non‑substantive wording changes to Vehicle Code §22349: it standardizes phrasing in the general 65‑mph prohibition, restates the 55‑mph rule for two‑lane undivided highways while clarifying that passing lanes are excluded from the lane count, and modernizes an intent clause to reference signage (instead of 'signing').
Who It Affects
The changes touch the Department of Transportation (Caltrans) and local traffic agencies responsible for engineering and traffic surveys, law enforcement agencies that issue and defend speed citations, traffic engineers who set posted speeds, and courts that interpret statutory language in speed‑limit disputes.
Why It Matters
By tightening statutory wording, the bill reduces avoidable disputes over lane‑counting and semantics that can complicate prosecution, defense, and administrative speed‑posting decisions. It also signals legislative expectation about signage placement on two‑lane roads without creating new funding or enforcement duties.

What This Bill Actually Does
AB2015 is a housekeeping bill that rewrites Section 22349 of the Vehicle Code to remove mixed or outdated phrasing while leaving the substantive speed limits intact. The first amendment restates the statute’s general prohibition on driving over 65 mph using uniform language; this is a drafting modernization rather than a policy change.
The text keeps the same exception referenced in §22356.
The bill’s second cluster of edits addresses the 55‑mph rule on two‑lane, undivided highways. It keeps the existing rule that a two‑lane, undivided highway shall not be driven at speeds over 55 mph unless the Department of Transportation or a local agency has posted a higher speed based on an engineering and traffic survey.
Crucially, AB2015 clarifies that a passing lane shall not be counted as an extra through lane when deciding whether a road qualifies as a two‑lane, undivided highway. That fix is aimed at recurring practical questions where intermittent passing lanes exist that might otherwise be read to change the statutory classification.The final change updates legislative intent language that previously used the term 'signing' to instead refer to 'signage' and directs reasonable signage on affected two‑lane roads — for example, placing signs at county boundaries where feasible.
That sentence expresses the Legislature’s expectation but does not create a funding stream or a statutory duty that triggers penalty if unmet.Taken together, the edits do three things: harmonize statutory phrasing, narrow a potential interpretive gap about passing lanes, and restate signage expectations. None of the revisions alters the numeric speed ceilings, changes enforcement mechanisms, or imposes new penalties; their practical effects will be felt mainly in reduced ambiguity during speed postings, citation defenses, and internal Caltrans/local agency guidance.
The Five Things You Need to Know
AB2015 leaves the numeric speed limits unchanged: 65 mph general cap and 55 mph on two‑lane, undivided highways absent higher posted speeds.
The bill standardizes the language of §22349(a) from mixed verbs ('may' vs 'shall') to a single, consistent prohibition phrasing.
Section 22349(b) explicitly states that a passing lane shall not be considered when counting through lanes for the 55 mph two‑lane classification.
Section 22349(c) replaces 'signing' with 'signage' and expresses legislative intent that reasonable signage be provided on affected two‑lane highways, including at county boundaries where possible.
AB2015 is described in the digest as technical and nonsubstantive; it creates no new penalties, funding, or enforcement powers.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Uniform prohibition language for 65 mph limit
This subsection rewrites the general prohibition against driving over 65 mph to use consistent statutory phrasing (favoring 'a person shall not' over the prior mixed construction). The change is drafting‑level: it does not alter the rule’s scope, exemptions referenced elsewhere, or enforcement authority, but it reduces grammatical ambiguity that can crop up in plea negotiations and judicial opinions.
Two‑lane definition and passing‑lane clarification
Subsection (b) retains the substance that two‑lane, undivided highways are subject to a 55‑mph cap unless a higher speed is posted after an engineering and traffic survey. The provision establishes two specific clarifications: it defines a two‑lane, undivided highway as having no more than one through lane in each direction, and it instructs that passing lanes shall not be counted when determining the number of through lanes. Practically, this reduces disputes where intermittent passing lanes could otherwise blur whether a road is a two‑lane facility for statutory purposes.
Signage intent on affected two‑lane roads
This subsection modernizes the Legislature’s intent language by replacing 'signing' with 'signage' and directs reasonable signage on affected roads, suggesting placement at county boundaries and other appropriate locations. The clause is expressive rather than mandatory: it signals legislative expectations to Caltrans and local agencies but does not appropriate funds or impose a sanctionable duty.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Traffic engineers and Caltrans staff — clearer statutory language reduces ambiguity when conducting engineering and traffic surveys and deciding where to post higher speeds.
- Law enforcement and prosecuting agencies — more consistent statutory phrasing and the explicit passing‑lane rule shrink an avenue for technical defenses to speed citations.
- Defense counsel and courts — the passing‑lane clarification limits interpretive disputes over whether intermittent lanes change highway classification, simplifying case law development.
Who Bears the Cost
- Department of Transportation and local traffic agencies — small administrative work to update internal guidance, training materials, and public‑facing documents to match the revised statutory text.
- Municipal and county public works departments — potential expectation to review signage placement in light of the intent clause, which could drive discretionary maintenance or new sign placements without dedicated funding.
- Clerks, publishers, and legal services — nominal cost to update statutory compilations, citation materials, and online references to reflect the revised language.
Key Issues
The Core Tension
The bill trades statutory clarity for the minimal risk that a court or litigant will read drafting fixes as substantive change: it aims to eliminate petty ambiguity, but changing words — even to harmonize phrasing — can reopen legal arguments and create expectations (about signage) without allocating funds to meet them.
Although presented as purely technical, textual edits can carry practical interpretive consequences. Courts sometimes treat rewording as evidence of legislative intent; defense attorneys could argue that a change in wording affects the statute’s meaning even if the Legislature labels the bill nonsubstantive.
The passing‑lane clarification reduces one clear ambiguity, but it leaves unanswered how to treat stretches where passing lanes appear intermittently or where lane configuration changes mid‑segment — those determinations still depend on engineering surveys and local factfinding.
The signage language expresses an expectation rather than a mandate and contains no appropriation. That creates a tension for local agencies and Caltrans: the Legislature signals that signage should exist at county boundaries and other points 'to the extent possible,' but the bill does not fund that work or create a statutory duty that could be enforced if an agency declines.
Implementation will therefore be managerial and discretionary, not transactional, which could frustrate localities that lack budgets for new signs but feel political pressure to act.
