We require noisy EVs for safety, but let’s stop the real killers: SUVs & gas
Much has been made of the supposed danger to pedestrians from quiet electric cars, to the point where the government now requires noisemakers on each EV model. But if we really want to save pedestrians, and everyone else, we need to target the actual culprits: big, pedestrian-killing SUVs and trucks, and the associated pollution they create.
The noisemaker rule has finally gone into effect, after being tweaked and pushed back over the course of several years. This has resulted in noisier EVs, each with its own noise (some worse than others), in the name of pedestrian safety.
NHTSA’s rule was based on a DOT analysis that showed hybrid vehicles to be 17% more likely to be involved in a pedestrian crash, when accounting for situational factors and vehicle age, though this analysis only included hybrid vehicles up through the 2011 model year. The law mandating the DOT to study and propose a rule for this dates back to 2010, when only a handful of electric cars were on the road in the US.
When implementing the noisemaker rule, NHTSA estimated these noisemakers will save 32 lives over the lifecycle of a single model year’s fleet. The rule requires noisemakers for EVs and hybrids when operating under 19 mph, the safest speeds for pedestrians. It does not require noisemakers or minimum decibel levels for gas-powered vehicles, even if those vehicles are equipped with engine stop/start or other technologies, which make the engine quieter or silent in certain situations, e.g., when slowing down and approaching an intersection, a place pedestrians are likely to be.
And as of February of this year, NHTSA has even opened an investigation into whether every electric vehicle since 1997 should be retrofitted, at some cost and difficulty, in order to comply retroactively with the noisemaker rule, in a way that virtually no other vehicle regulation has ever been implemented. The petition itself acknowledges there is no data yet showing relative danger from EVs that are not equipped with noisemakers.
What’s really deadly to pedestrians? SUVs
But there’s another common vehicle type that is 45% more likely to kill pedestrians: “light trucks,” a classification that includes SUVs and pickup trucks. Though “light” might be an odd word to apply, given that today’s SUVs are as large as literal tanks.
Light trucks are more deadly to pedestrians because they are larger and have higher hoods, resulting in decreased pedestrian visibility for drivers (with pedestrians obscured behind hoods, or behind other vehicles that are taller than the pedestrians or cyclists on the other side of them) and more deadly pedestrian impacts.
Cars are required to have bumpers designed for pedestrian safety, but light trucks have a different set of requirements. This leads to light trucks impacting pedestrians higher on the body, which causes more injury to the torso and head than the legs, resulting in deadlier collisions when a light truck is involved.
So not only are they more likely to hit pedestrians, but more deadly when they do.
And in fact, pedestrian death rates have skyrocketed in the US recently, up around 50% in the last decade, reaching the highest point in 40 years. Not coincidentally, SUV sales rates have increased in the same time frame. More deadly vehicles on the road have resulted in more pedestrian death, with the growth in SUVs responsible for killing at least a thousand pedestrians as of 2019 – which is a lot more than 32. Pedestrian deaths continued to rise sharply after 2019, so that number is surely significantly higher now.
The rise of SUVs is not solely a matter of consumer preference. Automakers use light truck exemptions to get out of emissions and safety rules and make more money, and actively push consumers toward these vehicles (even though barely anyone uses them for their intended purpose). How can Americans buy wagons, or city cars, or hatchbacks, when everything on the dealer lot is an SUV?
But running over people isn’t the only way that SUVs are dangerous; the pollution they make is orders of magnitude worse.
Noise itself is deadly
The DOT’s analysis of EV pedestrian safety explicitly did not consider environmental noise as a confounding factor to its research.
In a world choked with noise pollution from combustion engine vehicles, it stands to reason that quieter vehicles would be harder to hear. But if the world were not choked with noise pollution, those quieter vehicles would no longer be too quiet, they would be the norm. In a quieter world, EVs aren’t “harder to hear” once the sounds they make are no longer masked by the pathetic belching of combustion engines. Lower noise levels is a benefit of EVs, not a downside.
Noise itself is incredibly deadly to pedestrians – or rather, to everyone. Noise, mostly from cars but also from other combustion engines (airplanes, small off-road engines, etc.), greatly increases the rate of heart attacks in noisy areas, negatively affects the health of hundreds of millions of Americans, and is responsible for 12,000 premature deaths per year across Europe. Some research shows noise pollution to be just about as deadly as vehicle crashes overall.
The government even knows this to be the case, and has for some time, as it established the Office of Noise Abatement and Control through Congressional acts in the 1970s. This office was intended to study and regulate environmental noise in the US, but was – in a phrase that should be common to people who study social ills – defunded by Reagan in the ’80s.
So since noise is deadly, and since noise itself contributes to the problem the NHTSA wants to solve (by making it harder to hear quieter cars), then why don’t we work on making less noise instead of more?
And then, there’s air pollution
And finally, air pollution is deadlier than all of the above. And air pollution overwhelmingly comes from combustion engines.
Outdoor air pollution kills over 4 million people globally per year (including 100-200K in the US) and shortens global lifespans by two years. The health and environmental costs of fossil fuels add up to $5.3 trillion globally per year.
Much of this pollution and fossil fuel use comes from gasoline-powered vehicles, with larger vehicles like SUVs consuming more fuel and emitting more pollution than smaller vehicles (and tremendously more than zero-emission EVs). Vehicle pollution results in 4 million new cases of childhood asthma per year, sentencing these children to a lifetime of health issues.
Which brings up the point that this pollution is often not killing the people who emit it. Not only are children harmed for a lifetime by this despite not having contributed to this pollution, but environmental damage is disproportionately felt by the poor and is disproportionately emitted by the affluent.
This disparity was recently pointed out by the LA Times, in an article which Tesla CEO Elon Musk criticized despite his company being one of the solutions to this problem (perhaps someone could remind him that he’s still CEO of Tesla?). We already have studies showing that more EVs means cleaner air (with each EV bringing ~$10K in societal health benefits), and we know that more gas cars means dirtier air – and more deaths.
So if you want to reduce deaths, I’ve got a proposal
We know that:
- Big cars kill more pedestrians by running them over.
- Noisy cars kill more people by increasing stress, and also cover up the noises made by cars that operate at a more appropriate volume.
- Big, noisy combustion engines kill a whole lot of people by choking them to death with pollution.
Which means these noisemakers aren’t the most effective solution to the problem they are meant to solve. More effective solutions involve doing something about noise, and about air pollution, and about big pedestrian-murdering vehicles.
This also means that EVs aren’t the only answer. While a Hummer EV, the least-efficient EV, uses about as much energy as a Toyota Prius, one of the most-efficient gas-powered vehicles, the Hummer EV also takes up more space and causes more pedestrian danger. The trend toward SUVs threatens to eliminate emissions reductions from electrification, and while electric SUVs are still vastly efficient than any gas car, they are less efficient than smaller electric cars.
If we truly want to make the world safer for pedestrians, there are a lot of things that we can do outside of noisemakers. A discordant symphony of clown-car sound effects at every intersection isn’t going to be the big change that makes the world more walkable or cyclable.
To do that, we should put cars (or transit) on the road that don’t hog as much space, that don’t obscure pedestrians and cyclists from the view of other drivers, that don’t make the world too loud to think straight, that don’t choke everyone with stinky exhaust. These steps will give people more confidence to use their legs to make use of these more efficient, healthier, cheaper transportation methods – once these myriad benefits are no longer overshadowed by the problem of huge land yachts increasingly trying to murder them.
So here’s a modest proposal for society: If every EV needs a noisemaker for the safety gains mentioned above, then we should also take every “light truck” off the road for even more safety. If we’re thinking about making the EV rule retroactive to 1997, then we can make the much more effective SUV rule retroactive to 1997 as well. Do the latter, and you can have the former.
And if you won’t, then it’s not really about safety, is it?

Mining company Vale is turning to Caterpillar to provide this massive, 240-ton battery-electric haul truck in a bid to slash carbon emissions at its mines by 2030.
Caterpillar and Vale have signed an agreement that will see the Brazilian mining company test severe-duty battery electric mining trucks like the 793 BEV (above), as well as V2G/V2x energy transfer systems and alcohol-powered trucks. The test will help Vale make better equipment choices as it works to achieve its goals of reducing direct and indirect carbon emissions 33% by 2030 and eliminating 100% of its net emissions by 2050.
If that sounds weird, consider that most cars and trucks in Brazil run on either pure ethyl alcohol/ethanol (E100) or “gasohol” (E25).
“We are developing a portfolio of options to decarbonize Vale’s operations, including electrification and the use of alternative fuels in the mines. The most viable solutions will be adopted,” explains Ludmila Nascimento, energy and decarbonization director Vale. “We believe that ethanol has great potential to contribute to the 2030 target because it is a fuel that has already been adopted on a large scale in Brazil, with an established supply network, and which requires an active partnership with manufacturers. We stand together to support them in this goal.”
Vale will test a 240-ton Cat 793 battery-electric haul truck at its operations in Minas Gerais, and put energy transfer solutions to a similar tests at Vale’s operations in Pará over the next two-three years. Caterpillar and Vale have also agreed to a joint study on the viability of a dual-fuel (ethanol/diesel) solution for existing ICE-powered assets.
Vale claims to be the world’s largest producer of iron ore and nickel, and says it’s committed to an investment of between $4 billion to $6 billion to meet its 2030 goal.
Cat 793 electric haul truck
During its debut in 2022, the Cat 793 haul truck was shown on a 4.3-mile test course at the company’s Tucson proving grounds. There, the 240-ton truck was able to achieve a top speed of over 37 mph (60 km/h) fully loaded. Further tests involved the loaded truck climbing a 10% grade for a full kilometer miles at 7.5 mph before unloading and turning around for the descent, using regenerative braking to put energy back into the battery on the way down.
Despite not giving out detailed specs, Caterpillar reps reported that the 793 still had enough charge in its batteries for to complete more testing cycles.
Electrek’s Take
Electric equipment and mining to together like peanut butter and jelly. In confined spaces, the carbon emissions and ear-splitting noise of conventional mining equipment can create dangerous circumstances for miners and operators, and that can lead to injury or long-term disability that’s just going to exacerbate a mining operation’s ability to keep people working and minerals coming out of the ground.
By working with companies like Vale to prove that forward-looking electric equipment can do the job as well as well as (if not better than) their internal combustion counterparts, Caterpillar will go a long way towards converting the ICE faithful.

Argonne National Laboratory is building a new research and development facility to independently test large-scale hydrogen fuel cell systems for heavy-duty and off-road applications with funding from the US Department of Energy.
The US Department of Energy (DOE) is hoping Argonne Nat’l Lab’s extensive fuel cell research experience, which dates back to 1996, will give it unique insights as it evaluates new polymer electrolyte membrane (PEM) fuel cell systems ranging from 150 to 600 kilowatts for use in industrial vehicle and stationary power generation applications.
The new Argonne test facility will help prove (or, it should be said, disprove) the validity of hydrogen as a viable fuel for transportation applications including heavy trucks, railroad locomotives, marine vessels, and heavy machines used in the agriculture, construction, and mining industries.
“The facility will serve as a national resource for analysis and testing of heavy-duty fuel cell systems for developers, technology integrators and end-users in heavy-duty transportation applications including [OTR] trucks, railroad locomotives, marine vessels, aircraft and vehicles used in the agriculture, construction and mining industries,” explains Ted Krause, laboratory relationship manager for Argonne’s hydrogen and fuel cell programs. “The testing infrastructure will help advance fuel cell performance and pave the way toward integrating the technology into all of these transportation applications.”
The Hydrogen and Fuel Cell Technologies Office (HFTO) of DOE’s Office of Energy Efficiency and Renewable Energy is dedicating about $4 million to help build the new Argonne facility, which is set to come online next fall.
Electrek’s Take
It’s going to be hard to convince me that the concentrated push for a technology as inefficient as hydrogen fuel cells has more to do with any real consumer or climate benefit than it does keeping the throngs of people it will take to manufacture, capture, transport, store, house, and effectively dispense hydrogen gainfully employed through the next election cycle.
As such, while case studies like the hydrogen combustion-powered heavy trucks that have been trialed at Anglo American’s Mogalakwena mine since 2021 (at top) and fuel cell-powered concepts like Komatsu’s medium-sized excavator (above) have proven that hydrogen as a fuel can definitely work on a job site level while producing far fewer harmful emissions than diesel, I think swappable batteries like the ones being shown off by Moog Construction and Firstgreen have a far brighter future.
Speaking of Moog, we talked to some of the engineers being their ZQuip modular battery systems on a HEP-isode of The Heavy Equipment Podcast a few months back. I’ve included it, below, in case that’s something you’d like to check out.

Velocity truck rental is doing its part to help commercial fleets electrify by energizing 47 high-powered charging stations at four strategic dealer locations across Southern California. And they’re doing it now.
The new Velocity Truck Rental & Leasing (VTRL) charging network isn’t some far-off goal being announced for PR purposes. The company says its new chargers are already in the ground, and set to be fully online and energized by the end of this month at at VTRL facilities in Rancho Dominguez (17), Fontana (14), the City of Industry (14), and San Diego (2).
45 120 kW Detroit e-Fill chargers make up the bulk of VTRL’s infrastructure project, while two DCFC stations from ChargePoint get them to 47. All of the chargers, however, where chosen specifically to cater to the needs of medium and heavy-duty battery electric work trucks.
The company says it chose the Detroit e-Fill commercial-grade chargers because they’ve already proven themselves in Daimler-heavy fleets with their ability to bring Class 8 Freightliner eCascadias, Class 6 and 7 Freightliner eM2 box trucks, and RIZON Class 4 and 5 cabover trucks, “to 80% state of charge in just 90 minutes or less.”
At Velocity, we are not just reacting to the shift towards electric mobility; we are at the forefront with our customers and actively shaping it. By integrating high-powered, commercial-grade charging solutions along key transit corridors, we are ensuring that our customers have the support they need today. This charging infrastructure investment is a testament to our commitment to helping our customers transition smoothly to electromobility solutions and to prepare for compliance with the Advanced Clean Fleets (ACF) regulations.
David Deon, velocity president
Velocity plans to offer flexible charging options to accommodate the needs of different fleets, including both managed, “charging as a service” subscription plans and self-managed/opportunity charging during daily routes. While trucks are charging, drivers and operators will be able to relax in comfortable break rooms equipped with WIFI, television, snacks, water, and restrooms.
Electrek’s Take
While it feels a bit underwhelming to write about trucking companies simply following the letter of the law in California, the rollout of an all-electric, zero-emission commercial trucking fleet remains something that, I think, should be celebrated.
As such, I’m celebrating it. I hope you are, too.
