Advanced Driver Assistance Systems (ADAS) have become standard on modern vehicles, and with them comes a growing need for accurate calibration procedures. As the industry adapts to increasingly complex safety technology, regulators and lawmakers across the United States are beginning to take a closer look at how ADAS calibrations are performed.
Recent legislative proposals at both the state and federal level suggest that the next phase of the ADAS industry may include clearer standards, licensing requirements, and stronger documentation practices for calibration services.
While these proposals are still working their way through legislative processes, they provide a clear signal of where the industry is heading, and what shops in every state should be paying attention to right now.
ADAS Depot’s stance is that the industry needs standardization, and some of that may be driven by regulation.
FEDERAL DEVELOPMENTS
The ADAS Functionality and Integrity Act (H.R. 6688)
At the federal level, ADAS calibration has drawn significant attention. H.R. 6688, the "ADAS Functionality and Integrity Act," was introduced by Representative Diana Harshbarger (R-TN) with bipartisan co-sponsorship and referred to the House Energy and Commerce Committee.
On February 10, 2026, the Subcommittee on Commerce, Manufacturing, and Trade forwarded the bill to the full committee by voice vote as part of a package of twelve automotive safety bills, a significant procedural milestone.
The bill would direct the National Highway Traffic Safety Administration (NHTSA) to establish standardized calibration guidelines for vehicles starting with model year 2028. Specifically, it would require NHTSA to define allowable modification ranges and tolerances, test protocols, and performance validation metrics, and would require automakers to share vehicle tolerance and system sensitivity information with the public within thirty days of a new vehicle's release.
The REPAIR Act (H.R. 1566)
Also under consideration in the same committee hearings is H.R. 1566, the Right to Equitable and Professional Auto Industry Repair (REPAIR) Act. This bill addresses a related challenge: for ADAS calibration to be performed properly, independent shops need access to OEM-specified procedures, sensor tolerance values, and diagnostic tools. The REPAIR Act would require automakers to provide independent repair facilities with equitable access to the vehicle data and tools necessary to perform those calibrations.
NHTSA's AEB Mandate
Beyond legislation, NHTSA has finalized a rule requiring Automatic Emergency Braking (AEB), including pedestrian detection, on all new passenger vehicles by September 2029. This mandate will dramatically expand the number of vehicles requiring ADAS calibration after repairs, putting significant pressure on the industry to develop consistent calibration practices ahead of that deadline.
STATE-BY-STATE REGULATORY STATUS
In the absence of comprehensive federal standards, states have become the primary arena for ADAS calibration regulation. As of early 2026, a growing number of states have enacted specific laws governing some aspect of ADAS calibration. The following is a breakdown of where each state stands.
Alabama
No specific ADAS calibration legislation has been enacted. Shops operate under general consumer protection frameworks. Insurers in the state increasingly require documentation of ADAS calibration for relevant claims, but there is no state mandate.
Alaska
No specific ADAS calibration law. Alaska's geographic isolation and limited density of independent calibration shops reduce some legislative pressure, but consumers have fewer choices when calibration is improperly performed.
Arizona
Arizona has enacted meaningful ADAS calibration legislation. Senate Bill 1410 requires auto glass repair and replacement facilities to inform customers about ADAS calibration requirements and provide itemized descriptions of calibration work. Facilities are prohibited from representing that costs will be covered by insurance unless the insurer has confirmed coverage, and all calibration must meet or exceed manufacturer specifications. Violations carry civil penalties of up to $2,500 per incident.
Arkansas
No specific ADAS calibration legislation. Shops operate under general insurer and OEM guidelines without state mandates.
California
California is home to the most active automotive regulatory environment in the nation, yet its specific ADAS post-repair calibration framework lags behind states like Arizona and Maryland. The California DMV oversees extensive autonomous vehicle testing regulations that encompass ADAS as a subset, and broad consumer protection laws apply to auto repair shops generally, but dedicated ADAS calibration legislation with specific disclosure and reimbursement requirements has not yet been enacted.
Colorado
No specific ADAS calibration legislation. Colorado has been active on broader technology regulation, including AI and automated decision-making frameworks, but no calibration disclosure or insurance reimbursement bills have passed.
Connecticut
No specific ADAS calibration legislation. State insurance commissioners have issued guidance on ADAS-related claims, but formal statutory requirements have not yet been enacted. Bills have been discussed but not advanced.
Delaware
No specific ADAS calibration legislation. Shops operate under general consumer protection and auto repair statutes.
Florida
No specific ADAS calibration legislation comparable to Utah or Arizona. Florida's autonomous vehicle framework focuses primarily on AV deployment permitting rather than repair calibration standards. Florida's large vehicle fleet and aftermarket modification culture make it a state to watch for future action.
Georgia
No specific ADAS calibration legislation. Georgia's legislature has generally taken market-based approaches to automotive industry regulation.
Hawaii
No specific ADAS calibration legislation. Hawaii's small vehicle fleet and limited collision repair industry reduce the immediate legislative pressure for calibration standards.
Idaho
No specific ADAS calibration legislation. Idaho has a significant truck and off-road vehicle modification culture that intersects with the calibration problem, but the issue is managed through OEM guidelines and insurer requirements rather than state law.
Illinois
Illinois has seen active legislative engagement without a final enacted law. HB 5409 and HB 4719 were both introduced in a recent session but did not advance before the legislature adjourned. Illinois remains one of the more likely states to enact ADAS calibration legislation in coming sessions, given its legislative history and the size of its collision repair market.
Indiana
No specific ADAS calibration legislation. Indiana legislators have generally deferred to federal standards and OEM guidelines.
Iowa
No specific ADAS calibration legislation. Shops operate under general consumer protection statutes.
Kansas
No specific ADAS calibration legislation. Calibration-specific regulation has not been a legislative priority in recent sessions.
Kentucky
No specific ADAS calibration legislation. The state has a growing automotive industry presence but no calibration standards have been legislated.
Louisiana
No specific ADAS calibration legislation. Louisiana has significant vehicle modification activity, particularly in the truck sector, but no bills addressing calibration disclosure have been enacted.
Maine
Maine's legislature passed LD 1661, which mandates that liability insurance policies cover the costs of towing and storage for certain vehicles. This is a collision-adjacent insurance measure, but dedicated ADAS calibration legislation has not been enacted.
Maryland
Maryland is one of the most important states in ADAS calibration regulation. Senate Bill 793 (effective October 1, 2023) established consumer protections for glass repairs on ADAS-equipped vehicles, requiring facilities to inform customers if ADAS recalibration is required and to provide a written statement that work will meet or exceed OEM specifications before beginning any repair.
House Bill 920 further strengthened these protections by prohibiting insurers from steering glass claims to particular vendors and requiring that repair facilities inform customers both when recalibration is required and when it has been completed to OEM specifications.
Additionally, Senate Bill 789 (SB789), introduced in February 2026, proposes to go further. If passed, it would require businesses performing ADAS calibrations to obtain a specific license, maintain controlled environments that meet OEM specifications, possess proper calibration tools, and perform pre- and post-repair scans with documentation. Insurers would be prohibited from denying calibrations recommended by OEM procedures. Violations could carry fines of up to $5,000 per incident. If enacted, the legislation would take effect November 1, 2027.
Massachusetts
No dedicated ADAS calibration legislation, though Massachusetts has been among the most active states on right-to-repair issues. Voters approved a right-to-repair ballot initiative in 2020 that is directly relevant to ADAS calibration, since independent shops' ability to perform calibrations depends on access to OEM procedures and vehicle data.
Michigan
No state-level ADAS calibration legislation, despite Michigan being the historical heart of the American automotive industry and home to major OEM testing facilities. Michigan's congressional delegation is active on federal ADAS legislation, and Michigan-based stakeholders are closely watching H.R. 6688
Minnesota
No specific ADAS calibration legislation. Minnesota's collision repair industry is an active participant in national conversations about calibration standards.
Mississippi
No specific ADAS calibration legislation. No legislation is pending in this area.
Missouri
No specific ADAS calibration legislation at the state level. Senator Josh Hawley has been active at the federal level on autonomous vehicle safety, but state-level calibration legislation has not been advanced.
Montana
No specific ADAS calibration legislation. Montana's vast geography, high vehicle modification rates, and limited specialized repair infrastructure create significant calibration gaps that are managed through OEM guidelines rather than state law.
Nebraska
No specific ADAS calibration legislation. No bills addressing calibration standards have been introduced in recent sessions.
Nevada
No specific ADAS post-repair calibration standards comparable to Maryland or Arizona, despite Nevada having one of the most developed autonomous vehicle regulatory environments in the nation. Nevada's AV framework could provide a foundation for more detailed calibration regulation as technology evolves.
New Hampshire
No specific ADAS calibration legislation. New Hampshire's market-oriented regulatory philosophy makes it an unlikely early adopter of prescriptive calibration requirements.
New Jersey
New Jersey is among the more active states on ADAS-related consumer protection. Proposed legislation would mandate appraisal rights in every auto insurance policy, giving consumers more leverage in calibration reimbursement disputes, and additional bills have aimed to clarify ADAS repair processes and enhance consumer protection in the auto glass context. New Jersey's dense urban population and consumer-protective regulatory tradition make it a likely near-term adopter of comprehensive standards.
New Mexico
No specific ADAS calibration legislation at the state level. Representative Gabe Vasquez (D-NM) is a co-sponsor of H.R. 6688 at the federal level.
New York
New York enacted ADAS calibration legislation in 2025. Senate Bill S4879B passed both chambers and establishes standards for glass repair and ADAS calibration, requiring facilities to inform consumers whether recalibration is required, whether the facility can perform it to manufacturer specifications, and to provide itemized descriptions of the work. If a facility cannot perform the recalibration, it must inform the consumer in writing and direct them to a qualified facility. The NCOIL (National Conference of Insurance Legislators), which develops model legislative language for ADAS calibration, is based in New York and worked closely with legislators on this framework. New York is now one of the more consumer-protective states on ADAS calibration in the auto glass context.
North Carolina
No specific ADAS calibration legislation. North Carolina's growing automotive industry presence and significant collision repair market create natural constituencies for calibration regulation, but no legislation has advanced.
North Dakota
No specific ADAS calibration legislation. North Dakota's small population and limited urban collision repair infrastructure reduce the immediate legislative pressure.
Ohio
No specific ADAS calibration legislation at the state level, though Representative Bob Latta (R-OH) is working on an AV safety framework at the federal level for inclusion in surface transportation reauthorization.
Oklahoma
No specific ADAS calibration legislation. Oklahoma's significant truck modification culture and oil industry vehicle fleet create practical calibration challenges, but no state-level regulatory response has materialized.
Oregon
No dedicated ADAS calibration legislation, though Oregon has an active consumer protection framework and insurance regulations increasingly require proof of calibration for ADAS-equipped vehicles in claims processing. Oregon's proximity to California's regulatory environment positions it as a likely near-term adopter.
Pennsylvania
No specific ADAS calibration legislation. Pennsylvania's large collision repair market and active consumer protection legislative tradition create conditions favorable for future action. Pennsylvania-based ADAS calibration operators have been publicly outspoken about the need for federal standards and have contributed to national awareness of the calibration gap.
Rhode Island
No specific ADAS calibration legislation. Rhode Island's small size limits its independent legislative impact, though shops in the state face the same calibration uncertainties as those in neighboring states.
South Carolina
No specific ADAS calibration legislation, despite South Carolina being home to significant automotive manufacturing including BMW's US production facility.
South Dakota
No specific ADAS calibration legislation. South Dakota's limited legislative session schedule, small population, and market-oriented regulatory philosophy make state-level mandates unlikely in the near term.
Tennessee
No specific ADAS calibration legislation at the state level. Notably, Representative Diana Harshbarger (R-TN) is the lead sponsor of H.R. 6688 at the federal level. Tennessee's significant automotive manufacturing sector, including Nissan and Volkswagen facilities, creates a natural constituency for the federal standards its congressional representative is advocating.
Texas
No specific ADAS post-repair calibration legislation. Texas has moved in the opposite direction on vehicle oversight, Governor Greg Abbott signed HB 3297 eliminating non-commercial vehicle safety inspections as of January 1, 2025, removing one potential mechanism for detecting improperly calibrated ADAS systems. Texas's enormous vehicle fleet and significant collision repair industry make it a high-stakes jurisdiction for calibration standards.
Utah
Utah is the pioneer state for ADAS calibration regulation in the auto glass context, and its law has become the national template. Utah's law requires auto glass replacement facilities that perform calibration to provide itemized descriptions of the work performed, inform customers if calibration was not successfully completed, and meet or exceed manufacturer specifications. Civil penalties are $500 per violation for non-compliance.
Vermont
Vermont's legislature passed a measure directing the state's commissioner of financial regulation to study collision repair labor rates, aftermarket parts usage, and market conditions, with a report examining insurer influence over repair shop practices. This labor rate study is relevant to ADAS calibration because the question of fair compensation for calibration services is directly connected to the labor rate environment. No dedicated ADAS calibration legislation has been enacted.
Virginia
Virginia enacted SB 951, making auto insurance mandatory, a consumer protection measure with indirect implications for ADAS calibration, since uninsured motorists are unlikely to invest in proper post-repair calibration. Virginia's insurance regulatory environment is developing in ways that will increasingly require documentation of ADAS calibration for covered repairs, but dedicated calibration legislation has not been enacted.
Washington
No dedicated ADAS calibration legislation. Washington State has been active on right-to-repair issues generally, and its significant technology industry presence may accelerate future engagement with ADAS calibration as a data access and consumer protection issue.
West Virginia
No specific ADAS calibration legislation. State legislative bandwidth for automotive technology-specific regulation is limited.
Wisconsin
No specific ADAS calibration legislation. Wisconsin's collision repair industry and its proximity to Michigan's automotive policy debates have not yet translated into state-level mandates.
Wyoming
No specific ADAS calibration legislation. Wyoming's vast geography, high vehicle modification rates for off-road and agricultural use, and market-oriented regulatory tradition make state-level mandates unlikely in the near term.
What These Developments Mean For Repair Shops
The picture that emerges from a full look at all fifty states is one of accelerating but uneven regulatory activity. A handful of states, Utah, Arizona, and Maryland in particular, have built meaningful consumer protection frameworks around ADAS calibration. Many more are watching and moving toward action. And the majority of states currently have no specific ADAS calibration law on the books at all, sometimes explicitly deferring to Federal regulation, and often having no guidance whatsoever.
For repair facilities operating in states without legislation, this doesn't mean ADAS calibration obligations don't exist, it means they're being defined by insurer requirements, OEM service bulletins, and industry guidelines rather than state law. And as the federal landscape develops, that is increasingly likely to change.
The Growing Importance of Proper Calibration Infrastructure
ADAS technology is evolving rapidly. Sensors, radar units, and camera systems are now integrated into nearly every aspect of modern vehicle safety design, and with that complexity comes a greater need for reliable calibration tools, controlled environments, and properly trained technicians.
At ADAS Depot, we regularly work with shops that are expanding their ADAS capabilities, investing in calibration equipment, and building processes that allow them to meet OEM requirements with confidence.
Whether new regulations ultimately emerge at the state or federal level, one thing is becoming increasingly clear: ADAS calibration is no longer a niche service. It is quickly becoming a core part of modern vehicle repair.
