The bill directs the Secretary of Transportation to issue a rule—within one year of enactment—requiring devices that can receive and play AM broadcast signals to be installed as standard equipment in passenger motor vehicles manufactured after the rule’s effective date. Manufacturers may meet the requirement by installing receivers that can handle digital audio AM broadcasts (In Band On Channel DAB), but the definition explicitly excludes All-digital AM stations.
The statute preempts state and local laws on this subject, sets civil penalties tied to existing 49 U.S.C. enforcement provisions, and creates an interim labeling requirement for vehicles produced before the rule takes effect.
Beyond the equipment mandate the bill compels a Comptroller General study on disseminating emergency alerts (IPAWS) that assesses AM’s role relative to other technologies and whether existing systems can reach 90% of the U.S. population in crisis. The Secretary must report every five years on the rule’s impacts; the Secretary’s authority to issue the rule sunsets ten years after enactment.
Small-volume manufacturers get a longer compliance window.
At a Glance
What It Does
The Secretary must issue a rule requiring AM‑capable receivers as standard equipment in passenger motor vehicles sold or imported in the U.S.; manufacturers may comply using specified digital AM receivers. The rule must make access to AM stations easily available to drivers, preempts state rules, and is enforceable via civil penalties and DOJ actions tied to 49 U.S.C. enforcement provisions.
Who It Affects
Primary targets are passenger vehicle manufacturers, OEM infotainment suppliers, and AM broadcasters; FEMA, FCC, and emergency managers are engaged through consultations and the GAO study. Small-volume manufacturers (≤40,000 vehicles in 2022) get an extended compliance date.
Why It Matters
This is a federal equipment‑mandate designed to preserve over‑the‑air AM as a resilient emergency communications channel within vehicles—an intervention that affects automotive design choices, aftermarket and infotainment markets, broadcaster reach, and the federal-state balance for safety standards.

What This Bill Actually Does
The bill establishes a statutory command: within one year the Secretary of Transportation, working with FEMA and the FCC, must write a rule requiring devices capable of receiving and playing AM broadcast signals be installed as standard equipment in passenger motor vehicles manufactured after the rule’s effective date. "Device" is broadly defined to cover equipment that receives over‑the‑air radio signals and plays that programming in the vehicle. The bill explicitly allows compliance via devices that receive In Band On Channel (IBOC/DAB) digital audio AM broadcasts, while excluding so‑called All‑digital AM stations from that definition.
The statute builds in phased compliance windows. For most manufacturers the Secretary must set an effective date two to three years after the rule is issued; manufacturers that produced not more than 40,000 passenger vehicles for sale in the U.S. in 2022 get at least a four‑year delay.
For vehicles produced in the gap between enactment and the rule’s effective date, manufacturers that do not include AM receivers must provide clear labeling and cannot charge extra beyond the base price for AM access during that interim.The bill preempts any state or local regulation addressing access to AM broadcast stations in passenger vehicles, centralizing authority at DOT. Enforcement borrows existing motor‑vehicle penalty mechanics under title 49: violations expose responsible parties to civil penalties under 49 U.S.C. 30165(a)(1), and the Attorney General may seek injunctive relief under 49 U.S.C. 30163.
DOT must coordinate periodic reviews: at least every five years it must report to specified Congressional committees on the rule’s impacts and on possible IPAWS technology changes that would serve drivers and passengers.Separately, the Comptroller General must conduct a comprehensive GAO study on disseminating emergency alerts to the public. The study must evaluate AM stations’ resilience, advantages and limitations compared with other IPAWS channels, assess whether other technologies can reach at least 90% of the U.S. population at crisis times (including at night), and catalogue efforts to integrate new technologies into IPAWS.
The GAO must consult federal and state emergency officials, broadcasters, vehicle manufacturers, technology experts, and others, brief committees within one year, and follow with a written report 180 days after the briefing.Finally, the Secretary’s authority to issue and enforce the equipment rule sunsets ten years after enactment. The combination of a mandated baseline technology, a GAO study, periodic reviews, preemption, and a sunset creates a regulatory pathway that aims to sustain AM as a public‑safety channel while leaving room to reassess technological change.
The Five Things You Need to Know
DOT must issue the required rule within one year of enactment and may permit compliance via In Band On Channel digital audio AM receivers (but the bill excludes All‑digital AM stations).
The rule’s effective date must be set between 2–3 years after issuance for most manufacturers, but manufacturers that produced ≤40,000 vehicles for U.S. sale in 2022 get at least a 4‑year compliance window.
Vehicles produced after enactment but before the rule’s effective date that lack AM receivers require clear, conspicuous labeling and manufacturers may not charge extra beyond base price for AM access during that interim period.
Violations are enforceable through civil penalties under 49 U.S.C. 30165(a)(1), and the Attorney General may seek injunctions under 49 U.S.C. 30163, effectively folding enforcement into existing NHTSA‑style mechanisms.
The GAO must complete a comprehensive IPAWS study, brief Congress within one year of enactment, and deliver a formal report to committees within 180 days of that briefing; DOT must also provide five‑year impact reviews and the rule authority sunsets after 10 years.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Key technical and statutory definitions
Section 2 sets the vocabulary the rule will use: it defines "device," "AM broadcast band" (535–1705 kHz), "AM broadcast station," and two distinct digital categories—"digital audio AM broadcast station" (IBOC/DAB) and an explicit exclusion for "All‑digital AM stations." That distinction matters for manufacturers and broadcasters because the bill permits compliance with IBOC‑capable receivers but leaves room for regulatory and technical disputes over what counts as compatible hardware and software.
DOT must require AM reception as standard equipment
This subsection obligates the Secretary, in consultation with FEMA and the FCC, to create a rule that makes AM reception standard equipment in passenger vehicles manufactured after the rule’s effective date and sold or imported in the U.S. It also requires that access be provided in a way that’s "easily accessible to drivers," a phrase that will require DOT rulemaking decisions about user interface, placement, and safety controls. The allowance for IBOC/DAB receivers gives manufacturers a path to newer hybrid analog/digital systems without forcing an all‑digital transition.
Phased compliance: 2–3 years for most, 4 years for small manufacturers
DOT must set an effective date at least two years and no more than three years after rule issuance for most producers, while small manufacturers (≤40,000 vehicles in 2022) get a minimum four‑year lag. That creates an explicit volume‑based carve‑out intended to reduce burden on niche or low‑volume automakers; it also creates administrative complexity because DOT must verify manufacturers’ 2022 production figures and decide how later changes in production affect compliance timing.
Interim consumer disclosures and federal preemption
For the period between enactment and the rule’s effective date, manufacturers who ship vehicles that lack AM reception must give clear, conspicuous labeling and cannot charge extra for AM access beyond the vehicle’s base price. Separately, the statute preempts states and localities from imposing their own requirements governing AM access in vehicles, ensuring a single federal standard but blocking local policy experiments or stricter state rules.
Enforcement uses existing vehicle‑safety penalty mechanics
Rather than create a new penalty regime, the bill ties failures to comply to existing civil‑penalty authority in 49 U.S.C. 30165(a)(1) and gives the Attorney General injunctive authority under 49 U.S.C. 30163. Practically, this routes enforcement through the same apparatus used for other vehicle equipment standards, which simplifies statutory authority but raises questions about which DOT office will manage investigations and how penalties will be assessed for software or configuration noncompliance.
GAO IPAWS study, five‑year reviews, and a 10‑year sunset
The Comptroller General must study how emergency alerts reach the public, evaluate AM’s resilience and reach versus other IPAWS channels (including a specific look at whether non‑broadcast technologies can reach 90% of the population), and consult a broad list of stakeholders. GAO must brief committees within a year and report 180 days after that briefing. DOT, FEMA, and the FCC must jointly report to Congress at least every five years on the rule’s impacts. The Secretary’s rulemaking authority sunsets ten years after enactment, forcing a mid‑term policy reckoning about whether to continue, revise, or retire the requirement.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Rural and disaster‑exposed drivers—AM signals can travel long distances and penetrate areas with poor cellular coverage, so drivers in low‑connectivity regions gain a resilient channel for emergency alerts.
- AM broadcasters—stations operating on the AM band receive a protected, mandated distribution path into new vehicles, preserving audience and potential ad or underwriting value.
- Federal emergency management (FEMA/IPAWS) and state/local emergency managers—having a mandated receiver increases the guaranteed reach of over‑the‑air alerts, improving one dimension of nationwide alerting resilience.
- Infotainment suppliers that support IBOC/DAB manufacturers—vendors who already supply IBOC‑capable tuners can capture new OEM business as manufacturers adopt the permitted digital AM option.
Who Bears the Cost
- Vehicle manufacturers and OEM infotainment suppliers—must design, source, integrate, and certify AM receivers and interfaces across model lines, incurring hardware, software, and testing costs and potential redesign of consoles and wiring.
- Low‑volume manufacturers—although given more time to comply, these firms may face proportionally higher per‑vehicle costs and supply‑chain disruptions when eventually retrofitting standard equipment across limited production runs.
- Newer‑technology vendors and automakers focusing on IP‑native solutions—mandating AM reception risks locking in an over‑the‑air broadcast channel and could limit investment in alternative alerting modalities or require maintaining legacy hardware platforms.
- Regulatory agencies and DOJ—enforcement, coordination with FCC and FEMA, and the GAO study impose administrative workloads and resource allocation choices that may not be budgeted.
Key Issues
The Core Tension
The central dilemma is whether to mandate a single, resilient legacy technology (AM broadcasting) to guarantee over‑the‑air emergency reach now, at the cost of imposing hardware and integration burdens on vehicle manufacturers and potentially locking in an older standard while newer IP and satellite alerting technologies evolve. The bill prioritizes immediate resilience and nationwide uniformity over flexibility and technological transition.
The bill trades technological neutrality for an explicit emphasis on a single resilient channel: AM broadcasting. That choice protects a legacy, over‑the‑air medium that is robust in many disaster scenarios, but it may lock automakers and suppliers into installing hardware that could become redundant as IP and satellite systems mature.
The statutory allowance for IBOC/DAB receivers softens this by permitting hybrid digital transmissions, but the explicit exclusion of All‑digital AM stations creates a regulatory grey area on future digital upgrades and interoperability. DOT rulemaking will have to reconcile receiver performance standards, in‑vehicle antenna design, electromagnetic compatibility (especially important for electric vehicles), and software interface requirements to satisfy safety constraints while meeting the "easily accessible to drivers" mandate.
Implementation will hinge on interpretation details the bill leaves open: what counts as "access" that’s "easily accessible" without creating driver distraction; whether aftermarket and retrofit solutions qualify; how DOT will verify manufacturer compliance across increasingly software‑defined infotainment stacks; and how the agency will treat vehicles imported with non‑U.S. certified radios. The preemption clause simplifies the market by removing state patchworks, but it also prevents states from piloting alternative alerting strategies.
Finally, the ten‑year sunset forces a policy decision point: if IPAWS or other technologies substantially improve reach in that window, Congress will face pressure either to renew the mandate or accept a shift away from broadcast-based alerting.
