Bill Summary · S 4879

Summary — S.4879 (Introduced Nov 17, 2025)

Title: Establishes standards for glass repair and calibration of advanced driver assistance systems
Status: Substituted by A6943B (6/12/2025)
Introduced: 2025-11-17
Sponsors: Patricia Fahy (primary), Christopher Ryan (cosponsor)
Committee referrals / actions: Referred to Senate Law and Public Safety Committee; also referred to Consumer Protection (2/13/2025). Advanced and amended on third reading (May 2025). Substituted by A6943B (6/12/2025).

Note on source material: The bill package provided includes several PDF streams and an “Introduced Version” that appears to be a supplemental appropriations act (a $3 million appropriation to a State Police Internet Crimes Against Children Unit). The full statutory text for S.4879 (detailing glass repair/ADAS calibration standards) was not present in the materials supplied. The summary below therefore separates (A) what the bill’s title indicates and likely policy scope, and (B) what is actually found in the supplied introduced/version files.

A. Intended purpose (from bill title)

Based on the official bill title, S.4879 is intended to establish standards governing:
- Repair and replacement of automotive glass (windshields, side/rear windows); and
- Calibration and verification procedures for Advanced Driver Assistance Systems (ADAS) after glass repair or replacement.

Primary goals implicit in that title:
- Ensure ADAS components (e.g., lane-keep assist, adaptive cruise control, automatic emergency braking, collision avoidance cameras/sensors) remain properly calibrated after windshield/glass service;
- Protect vehicle safety by requiring technicians or repair facilities to follow manufacturer (OEM) procedures and use appropriate tools/equipment for calibration;
- Require consumer disclosures at the point of repair about whether ADAS calibration will be performed, who will perform it, costs, and any limitations;
- Set training, certification, recordkeeping, and enforcement requirements for glass repair shops and technicians.

Because the bill text was not included, specific provisions (definitions, required calibrations, certification pathways, penalties, or funding) could not be confirmed.

B. Supplied introduced/version text (mismatch)

The “Introduced Version” file in the package contains a supplemental appropriation for the State of New Jersey:
- Appropriates $3,000,000 from the General Fund to the Department of Law & Public Safety — Division of State Police — Internet Crimes Against Children (ICAC) Unit.
- Purposes listed: training, equipment, vehicle purchases/outfitting, software licenses, and staff mental health initiatives.
- Effective: immediately; unexpended balance to be carried forward for same purpose.

This appropriation text appears unrelated to the glass/ADAS subject in S.4879’s title; it may reflect a clerical or file-mapping error in the provided materials.

Affected parties (if bill follows title)

  • Motor vehicle owners and lessees whose vehicles have ADAS-equipped glass (windshield, cameras, sensors);
  • Automotive glass repair and replacement businesses;
  • Independent and franchise vehicle repair shops; certified ADAS calibration technicians;
  • Auto insurers (potentially, if calibration affects claims/costs);
  • Vehicle manufacturers (OEM calibration specifications and tooling).

Procedural / timeline notes

  • Introduced 11/17/2025 (per header).
  • Multiple committee and floor actions in May 2025 (advancements, amendments); recorded as Amended on Third Reading (S4879A/B) in May 2025.
  • Substituted by Assembly bill A6943B on 6/12/2025 — A6943B should be consulted for the enacted/working text and final policy language.

Recommendation / next steps for readers

  • Consult the text of A6943B (the substitute bill) for the final or operative language that replaced S.4879. A6943B will contain the concrete requirements, definitions, and enforcement mechanisms.
  • If evaluating regulatory or compliance impacts, obtain the full bill text (or A6943B) and any fiscal notes or agency reports that outline implementation costs, certification processes, and enforcement strategy.
