This bill revises the statutory definition of a “speed trap” and creates procedural and evidentiary guardrails for electronic speed enforcement. It lays out when a location qualifies as a speed trap, specifies minimum training for officers using radar and laser equipment, requires equipment calibration by an independent certified facility, and restricts enforcement where underlying traffic surveys are not up-to-date.
For professionals in local government, traffic engineering, law enforcement, and defense practice, the bill changes how jurisdictions justify posted speeds and how prosecutors must prove citations that rely on electronic speed measurement. It shifts several technical duties—training, calibration, and survey currency—into statutory prerequisites for admissible speed citations, which will affect enforcement practices and litigation risk in many jurisdictions.
At a Glance
What It Does
The bill defines a speed trap as a measured road segment used to compute speed by distance/time or as a posted prima facie limit lacking a recent engineering and traffic survey when enforcement uses radar or other electronic speed devices. It requires certified training for officers who operate radar and additional training for those using laser devices, mandates independent calibration of speed-measuring equipment, and ties admissibility of citations to compliance with those requirements.
Who It Affects
State and local law enforcement agencies that issue speeding citations using radar, lidar, or other electronic devices; local governments that set prima facie speed limits; traffic engineers who prepare or revalidate engineering and traffic surveys; and defense attorneys and prosecutors handling speed-related citations.
Why It Matters
By codifying training, calibration, and survey currency as elements of a lawful enforcement action, the bill raises the bar for admissible speed citations and creates new procedural points of challenge. Municipalities that have not updated speed surveys or that rely on electronic enforcement will need to align operations or face increased dismissals and litigation.

What This Bill Actually Does
The bill starts by giving the term “speed trap” two concrete meanings. One is a roadway segment whose boundaries are defined so that a vehicle's speed is calculated by timing it over that fixed distance.
The other is a segment where a prima facie speed limit is posted but not supported by a sufficiently recent engineering and traffic survey when enforcement is done with radar or other electronic devices. Certain places—local streets, school zones, senior zones, business activity districts, and some statutorily defined speed-limit areas—are carved out from that second meaning.
Enforcement using electronic devices becomes procedurally vulnerable unless the officer and the equipment meet statutory prerequisites. The bill requires officers to complete specified training courses approved by the Commission on Peace Officer Standards and Training before radar or laser citations are presented in court.
It also requires prosecutors to establish, as part of their case, that the officer completed the training, that an engineering and traffic survey is current for the location, and that the device complied with operational standards and calibration requirements before issuing the citation.On engineering and traffic surveys, the bill adopts a presumption based on survey recency: a posted prima facie limit supported by a survey within the statutory window is treated as justified for enforcement with electronic devices; if the survey is older than the window, enforcement becomes susceptible to the speed-trap rule unless a registered engineer separately evaluates the roadway and certifies that conditions have not significantly changed. The statute also anchors equipment reliability to national operational standards and periodic independent calibration, and it makes calibration and proof of that calibration part of the prosecutorial predicate for using electronic measurement evidence in court.Taken together, the text reframes several previously technical compliance items—training hours, device maintenance, survey currency, and engineer verification—into statutory elements that determine whether a speeding citation based on electronic measurement will stand as evidence.
That changes how agencies must structure training schedules, calibration contracts, and periodic traffic studies if they want to sustain electronic enforcement without routine evidentiary challenges.
The Five Things You Need to Know
The bill treats a roadway segment used to time vehicles over a known distance as a speed trap, explicitly tying distance/time measurement setups into the definition.
Prosecutors must prove the arresting officer completed POST-approved training before offering radar or laser-based speed evidence.
Speed-measuring devices must meet NHTSA minimal operational standards and be calibrated by an independent certified facility within a statutory calibration window.
A supporting engineering and traffic survey must have been conducted within a specified multi-year window for a posted prima facie limit to be enforceable with electronic devices; a registered engineer can extend that window by certifying no significant changes.
The statute exempts certain areas—local streets as functionally classified, school zones, senior zones, and business activity districts—from the survey-related speed-trap rule.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Two definitions of 'speed trap'
This subdivision gives the term a two-part definition: (1) a defined road segment used to compute speed by timing a vehicle over a known distance, and (2) a posted prima facie speed limit enforced with electronic devices that lacks a supporting engineering and traffic survey. The practical effect is to fold both geometry-based timing enforcement and survey-supported posted limits into the ‘speed trap’ concept, which drives later evidentiary rules.
Terminology and scope: local streets, school/senior zones, business districts
Subdivision (b) sets out who and what fall inside or outside the statute. It borrows established definitions (for example, school zones) and establishes objective criteria for what counts as a local street or road (functional classification, roadway width, uninterrupted length, lanes). That matters because the statute explicitly excludes these categories from parts of the speed-trap analysis, limiting where the stricter survey rules apply.
Officer training and device standards as evidentiary predicates
This provision makes officer training and device readiness part of the prosecution’s burden. It requires completion of a POST-approved radar course (a minimum classroom threshold is set in the bill) and additional training for laser operators. Before a citation based on electronic measurement is offered, the prosecution must show the officer completed required training and that the device met national standards and calibration requirements. That turns administrative training and maintenance into courtroom facts that must be proved.
Calibration and equipment reliability
The bill requires that the radar, laser, or other device meet or exceed NHTSA minimal operational standards and have been calibrated at an independent certified facility within a specified interval before the alleged violation. This provision channels challenges over device accuracy into discrete proof problems—show me the calibration certificate from a qualified third party—and creates compliance obligations for agencies that deploy electronic speed-measurement tools.
Survey currency and the extended-review exception
This section fixes the time windows for how recent an engineering and traffic survey must be to justify a posted prima facie limit when electronic enforcement is used. It establishes a standard multi-year period and a longer period if a registered engineer conducts a focused evaluation and confirms no material changes in roadway or traffic conditions. That creates a two-path validation: automatic currency within the standard window, or engineer-certified currency for an extended window.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Drivers and vehicle owners contesting citations — They gain concrete procedural grounds to challenge radar/laser-based tickets when officer training, device calibration, or survey currency is not provable.
- Defense attorneys — The statute creates specific, documentable predicates (training records, calibration certificates, recent surveys) that defense counsel can demand and litigate, increasing leverage in case resolution.
- Registered traffic engineers — The bill elevates the role of a registered engineer in confirming that older surveys remain valid, creating new consulting and certification work tied to extending survey life.
Who Bears the Cost
- Local and state law enforcement agencies — Agencies must invest in POST-certified training, track officer certification, schedule device calibrations with independent facilities, and retain documentary proof to sustain prosecutions.
- Municipalities and transportation departments — To keep posted prima facie limits enforceable, jurisdictions will need to fund more frequent engineering and traffic surveys or pay engineers to validate older studies.
- Independent calibration and testing facilities — These providers face higher demand and potential bottlenecks, and they must meet certification expectations to support enforcement evidence.
Key Issues
The Core Tension
The central tension is between preventing abusive or poorly supported electronic speed enforcement and preserving agencies’ ability to use accurate, efficient tools to keep roads safe: raise the standard too high, and legitimate enforcement is hamstrung by paperwork and capacity limits; set it too low, and drivers face automated enforcement without meaningful safeguards. The bill tries to thread that needle by requiring training, calibration, and survey currency, but doing so forces trade-offs among legal certainty, administrative burden, and on-the-ground traffic safety.
The bill converts technical prerequisites into evidentiary gatekeepers. That clarifies enforcement standards but also creates operational friction.
Agencies that previously relied on periodic in-house checks now must secure third-party calibration certificates and maintain officer training logs as litigation-grade records; failure to do so risks dismissal of otherwise valid speeding behavior. The registered-engineer exception extends the lifecycle of older surveys, but it also invites disputes over what constitutes a ‘significant change’ in conditions, a fact-intensive inquiry that is fertile ground for expert disagreement.
Another implementation challenge is capacity: certified calibration facilities and POST-classroom slots are finite. A sudden uptick in demand—especially in populous counties or after a statutory effective date—could create delays that, paradoxically, increase the frequency of invalidated citations.
Finally, by excluding local streets and certain zones from the survey-based limitation, the statute draws a line whose practical fairness will depend on local road classifications and how municipalities mark and document boundaries—matters that vary widely across jurisdictions and may themselves trigger litigation.
