AM Radio For All Vehicles Legislation Reintroduced (agweek.com) 120
A bipartisan group of legislators has reintroduced the AM Radio for Every Vehicle Act of 2025, aiming to mandate AM radio in all new vehicles at no additional cost. Adweek reports: The AM Radio for Every Vehicle Act was first introduced in May 2023. It continued to take on new co-sponsors through the fall of 2024. It was reintroduced as the AM Radio for Every Vehicle Act of 2025 with 62 cosponsors. Upper Midwest senators showing support for the bill include Sens. John Hoeven and Kevin Cramer R-North Dakota, and Sens. Amy Klobuchar and Tina Smith, DFL- Minnesota.
If enacted, the bill would require the Department of Transportation to issue a rule requiring new vehicles to maintain access to broadcast AM radio at no additional cost to the consumer and provide small vehicle manufacturers at least four years after the date DOT issues the rule to comply. The act also requires automakers to inform consumers, during the period before the rule takes effect, that the vehicles do not maintain access to broadcast AM radio. "With 82 million Americans tuning in each month, AM radio delivers more than just emergency alerts," says the National Association of Broadcasters in a news release. "It connects communities through hyper-local content, including news, weather and diverse cultural programming," according to a news release from the National Association of Broadcasters."

Right, and by removing the AM radio from vehicles the automakers can be "sloppy" with their shielding of electronics and get new car buyers to sign up for some kind of subscription service to make up for it, and get a cut of the service fee as a result of course. They can go cheaper on the manufacturing, add fees for subscriptions or a special order on an AM radio add-on, to make money on both ends of the deal.
If people want higher quality audio then they can still get cellular or satellite service in their vehicles. If they have an EV with improper shielding then they can't even bring a portable AM radio in the EV and expect reliable reception. Part of the AM radio requirement will force the EV makers to put in the effort on proper shielding so their own AM radio works, and it has the side benefit of minimizing interference to adjacent vehicles.
Another side benefit is this will mean less interference with 2-way radios like CB, ham, GMRS, and business/emergency bands should people want a 2-way radio for emergency communications or as part of their job.

Your points in support of this law are primarily regarding its side benefits. If you want to see EVs being less sloppy in their shielding, pass a law that mandates it. Otherwise you run the risk that manufacturers cynically comply with the requirement: the AM radio feature gets buried 4 menu layers deep, and shielding is improved the minimum amount required to barely pick up a strong signal.

Then this whole situation does not apply very well since you just stop driving and you get signal back because the interference went away. Anyone that drives in the rural areas knows, especially for older vehicles, that the alternator can often be a problem when listening to AM, and you get that last bit of reception by turning the vehicle off.
This applies to cell phones also, you lose the last bit of range when you charge them so you need to unplug/remove to get reception.

It was last week when Florida was having that unusually cold weather that he'd texted me and asked why the Mustang Mach-E he'd just picked up had burned up 20% of its charge driving just from the rental place to his home. Being something of the EV guru in the family, I explained to him that if he was running the heat (which he was), that'd chew through the battery faster than Trump with a hamberder. He also asked me how to recharge it and I told him that since it's not a Tesla, his two options are either borrowing my NACS to CCS1 adapter and using Tesla's Superchargers, or just using Google maps to search for CCS EV fast chargers along his route and hoping they're not broken. Of course, I also threw in that charging on-the-go isn't something I frequently have to deal with since I have charging at home.
He arrived at his hotel in Tampa with about 18% battery remaining and it turned out the hotel only had Tesla destination chargers, which requires an entirely different sort of NACS adapter (NACS to J1772) than the one I'd loaned him. Oops. I text him back and tell him to go to a nearby Supercharger where the adapter I loaned him actually would do him some good, where unfortunately he then discovers that there's something wrong with the car itself regarding its ability to DC fast charge. Still unwilling to throw in the towel, he then tries an Electrify America charger with the same result of the car failing to charge. Defeated, he returns to the hotel with a nearly-dead EV and ends up calling the rental company in the morning to swap the car out for one that runs on gas.

EV manufacturers want to get away with the equivalent of dumping their toxics in the river, although in this case it is failing to contain the racket that their EV's electric motors make in the electromagnetic spectrum. There is more than just AM radio at stake, although that is enough. You see a sign to tune to 1690 for important highway information, what do you do then? You can't even bring a portable AM radio to hear it because your EV's motors are making so much noise your AM radio receiver only hears static.
But there is radio communications in the shortwave band, just a few megahertz higher in the spectrum than AM radio, that also gets blocked. Ham radio is there. Mostly that is a hobby, but during some exceptional times of adversity, messages can be passed in no other way. Getting a list of wildfire victims across the mountains to Red Cross headquarters for an event can sometimes have no other means. Such communications requires no other infrastructure, such as cell towers that get burned to the ground in the wildfire. Hams can just string a low to the ground wire, send signals mostly straight up, and communicate for 100 miles without towers in between to repeat the signal. The technique, called Near Vertical Incident Skywave (NVIS), relies mostly on signals in the 80, 60, and 40 meter bands, which are 4, 5, and 7 megahertz, and which can be wiped out by noisy EV motors.
Additionally, if a hurricane knocks down every broadcast tower in Florida, so there are no radio or TV stations nor electricity to power them, you can still get messages directly to Floridians via AM radio using 50,000 watt transmitters of clear channel radio broadcasting in Atlanta and New Orleans. In this case, size matters, and those transmitters will punch thru the night sky and get information where it needs to be and to whomever needs to hear it. FM radio will not do this, as it is mostly limited to line of sight propagation.
So lets keep AM radio in our cars, and incidentally do the right thing and keep the industry from, once again, taking the shortcut of simply dumping their inconvenient electromagnetic effluents on the rest of us and let us use the radio spectrum the same way that we've been doing it for the last 100 years.

Greater Distance, low power, simplicity make AM still a very effective communications protocol. Keep it. And go ahead and mandate it.

The spectrum has been polluted for decades already. Triac based lamp dimmers and motors with brushes all play havoc with AM. That stuff has been common place since the 1960s. Simplicity is great but there's a reason why we upgraded from telegraph lines to digital communications.

It's pollution, this time of the electromagnetic spectrum.
EV manufacturers want to get away with the equivalent of dumping their toxics in the river, although in this case it is failing to contain the racket that their EV's electric motors make in the electromagnetic spectrum.
Electromagnetic interference is in no way comparable to dumping toxic substances into a river.

That may be the number of people in range of a broadcast, but I seriously doubt it has that many listeners anymore.
If AM radio dies (Score:2)
One certain political party would lose one of its major mouthpieces. A lot of people in the service industry drive from job to job listening to talk shows on the van radio. If AM were eliminated from these vans, then they would have to bring their own battery powered radio to continue listening to these talk shows.

The AM radio has long been standard equipment on cars and used for emergency broadcasts. Sure you could replace it with a new standard, but that would require new infrastructure for the new system, plus running both systems in parallel for long enough for older cars that still have AM to be retired out of the market. Plus if other countries didn't migrate to the same standard or took longer to do it you'd end up with more regionally varied models depending on the country the car is built for.

The data is not clear but I bet if you looked hard enough you would find most of these AM stations are some sort of religious format stations.
I would submit that this isn't much of an argument. Just because one doesn't like the content doesn't mean that it's justified in removing functionality that is relatively difficult for an end user to implement. Sure, one could get a portable AM radio and keep it in the car, but it's extremely challenging to get a useful AM antenna implemented in an object that significantly attenuates the signal if the antenna is in the cabin.
