IIJA Section 24220 — Vehicle Kill Switch Mandate

• Law: Infrastructure Investment and Jobs Act (Public Law 117-58), Section 24220
• Passed: November 2021; implementing regulations expected by NHTSA ~2026–2027
• Vote: Senate 69–30 (August 2021); House 228–206 (November 2021)
• Signed by: President Biden

The government decided it gets to decide whether your car moves. Not a police officer. Not a judge. A sensor. An algorithm. A camera pointed at your face while you drive to work. Congress buried this mandate inside a 2,700-page infrastructure bill, slapped "roads and bridges" on the cover, and most Americans had no idea what was in it until the cars they buy in the next few years come with a system that can lock them out of their own vehicle. No warrant. No traffic stop. No human officer making a judgment call. Just a machine that decides you look impaired — and stops your car.

How It Passed

Section 24220 was tucked into the Infrastructure Investment and Jobs Act — a massive bipartisan bill advertised as funding roads, bridges, broadband, and water systems. The vehicle kill switch provision was not the subject of standalone hearings. Congress never held a dedicated debate on whether it was appropriate to mandate surveillance hardware in every new American vehicle. It was bundled with hundreds of billions of dollars in spending that members wanted in their districts, and the kill switch rode along for free.

The Senate passed the bill 69–30. The House passed it 228–206, with 13 Republicans crossing over to vote yes. President Biden signed it in November 2021. Most voters had no idea Section 24220 existed.

NHTSA — the agency charged with writing the actual technical rules — missed its own November 2024 deadline for a final rule. In its February 2026 report to Congress, NHTSA admitted that available technologies do not yet meet the required accuracy levels. The technology isn't ready. The mandate is still on the books.

What It Does To You

Section 24220 directs NHTSA to establish a federal safety standard requiring every new passenger vehicle to be equipped with "advanced drunk and impaired driving prevention technology." The system must:

• Passively monitor your driving performance, behavior, or physiological state for signs of impairment.
• If impairment is detected, prevent the vehicle from starting — or bring it to a stop.

"Passive monitoring" is not a breath test at the door. The technologies under consideration include:

• Interior cameras scanning your face 24 hours a day you are in the vehicle — tracking eye movement, gaze direction, head position, and blinking patterns
• Infrared sensors reading your heart rate and blood alcohol concentration through your skin via the steering wheel or gear shift
• AI behavior analysis monitoring your lane positioning, braking, acceleration, and steering inputs in real time
• Breath sensors embedded in the cabin air — sensors that can be triggered by a diabetic's breath chemistry, certain medications, or even a passenger's alcohol consumption

The system is watching you constantly. Every drive. Every mile. And when it decides something is wrong — a late-night yawn, a glance down at the radio, a medical condition that affects your breath chemistry or heart rate — it can lock you out of your car. You have no immediate recourse. There is no officer to argue with. There is no number to call. The machine decides, and you are stranded.

Rights It Strips

Fourth Amendment. This is continuous warrantless surveillance of a private citizen inside a private vehicle. No probable cause. No warrant. No officer making an individualized judgment about whether you are a threat. A sensor is scanning your face, your eyes, your heartbeat, and your breath every moment you drive. The government does not need to obtain a warrant to collect this because the hardware is mandated to be in your car by law.

Fifth Amendment. Your vehicle can be disabled — your property rendered inoperable — based on a sensor reading. No hearing. No adjudication. No opportunity to contest. The deprivation is instant, and the "due process" comes, if at all, only after you are already stranded on the side of a road.

Right to Travel. The Supreme Court has recognized a fundamental right to travel between states as implicit in the structure of the Constitution. Requiring citizens to pass a continuous physiological examination administered by a government-mandated sensor system as a condition of exercising that right has no precedent in American constitutional history.

Property Rights. You own your car. Congress has mandated that your car come pre-installed with monitoring hardware you cannot remove, operating in ways you cannot inspect, generating data about you that you may not be able to access or control.

Documented Abuses / Documented Harms

NHTSA's own February 2026 report to Congress is damning. The agency acknowledged that even at 99.9% accuracy — a precision level no real-world sensor system achieves — the kill switch system would generate millions to tens of millions of false positives per year across 227 billion annual driving trips in the United States.

Read that again. At near-perfect accuracy, millions of sober, legal drivers would be locked out of their vehicles by a machine making a mistake. A late-night yawn triggers the eye-tracking system. A glance at the radio triggers the gaze-direction sensor. Diabetes, certain prescription medications, and low-carb diets can produce elevated breath alcohol readings that trigger the cabin air sensors. A pregnant woman's changing physiology. A passenger who had a beer. The machine cannot tell the difference, and the machine controls your car.

The system infrastructure also creates a permanent surveillance expansion risk. Nothing in Section 24220 limits the monitoring to alcohol and drugs. Once cameras, infrared sensors, biometric systems, and AI behavioral analysis are mandatory hardware in every vehicle, the same infrastructure can be repurposed by rule change — no new legislation required — to monitor for drowsiness, distraction, "aggressive driving," or any other condition NHTSA or a future administration decides warrants intervention. The law creates the chassis. Future bureaucrats fill it in.

Who Pushed This

The vehicle kill switch mandate did not emerge organically from safety advocates. The institutional coalition pushing it included:

• NHTSA bureaucrats who have sought expanded vehicle monitoring authority for decades and found a legislative vehicle in the infrastructure bill
• Insurance industry lobbyists — insurers benefit directly from in-vehicle monitoring: a population of cars that can be disabled reduces their liability exposure and creates a market for premium reductions tied to monitoring compliance
• The automotive industry — major manufacturers were already developing driver monitoring systems for their own liability protection; a federal mandate levels the competitive playing field and ensures every car buyer is in the monitored ecosystem
• Senators and representatives who packaged the provision inside popular infrastructure spending to avoid standalone scrutiny

No grassroots constituency asked for this. No citizen petition demanded that the government install cameras in their cars. This was an inside game played between lobbyists, bureaucrats, and legislators using an infrastructure bill as cover.

Key Votes

• Senate: 69–30. Every senator who voted YES voted to mandate surveillance hardware in your car.
• House: 228–206. Thirteen Republicans crossed the aisle to vote YES.

The senators and representatives who voted YES accepted the kill switch mandate as the price of the broader infrastructure package. They had the option to strip Section 24220 from the bill. They did not.

Senators and House members who voted NO are clean on this specific provision.

Why This Matters for We The Citizens

The vehicle kill switch is one of the clearest examples of how surveillance infrastructure gets embedded in American life: quietly, buried in unrelated legislation, without public debate, sold as a safety measure, and built in a way that is nearly impossible to remove once it exists. Every new car will have the hardware. The data stream will exist. The remote disable capability will exist. Future administrations will have access to it.

A politician who voted YES on IIJA accepted warrantless biometric surveillance of American drivers as a routine feature of infrastructure legislation. That vote is on the record. It tells you everything you need to know about how seriously they take the Fourth Amendment and the right to travel freely without government monitoring.

The question for We The Citizens is simple: does your representative think the government should have a kill switch on your car? Their 2021 vote already answered that question.
