How to Choose a Safer Car
Whether you are picking a budget commuter or a premium family SUV, there are proven ways to maximize your safety β and some conventional wisdom that's simply wrong.
There Is No Single "Safest" Car
People constantly ask: "What is the single safest car on the market?" In reality, we will never know. Crash tests are standardized laboratory experiments. Real-world crashes are chaotic and unpredictable. The vehicle that perfectly protects its occupants in a 40 mph offset crash might perform differently if the impact angle changes by just a few degrees.
Instead of searching for a mythological perfect vehicle, you should focus on minimizing your overall risk by checking these crucial boxes, tailored to your specific needs and budget.
Yes, we see the irony. We just said there's no single safest car β and then on our homepage, we rank the safest cars. We stand by both statements. Philosophically, "the safest car" depends on the crash you're in, who you are, and how you drive. But we live in the real world, and you have to actually buy something. So we drew a line in the sand using the best data available β IIHS death rates, crash test scores, and real-world outcomes β knowing it's our best educated guess, not an immutable truth. Think of our rankings as "the cars most likely to keep you alive," not "the one car that will survive every conceivable scenario." π€·
1. Weight Matters β But Only Up to a Point
All else being equal, a heavier vehicle provides better protection in a multi-vehicle collision. The laws of physics dictate that in a crash between a light car and a heavy car, the lighter car will experience a much higher deceleration force. Longer front ends also mean more crumple zone to absorb energy before the passenger compartment is breached.
But there's a clear ceiling. A February 2025 IIHS study found that the safety benefits of additional weight plateau once a vehicle exceeds the fleet average of roughly 4,000 lbs.
for every +500 lbs
for every +500 lbs
"For American drivers, the conventional wisdom is that if bigger is safer, even bigger must be
safer still. These results show that isn't true today."

π― The Sweet Spot
Midsize SUVs and large sedans (roughly 3,500β4,200 lbs) offer the best balance: enough mass for strong self-protection, without the diminishing returns and added danger to other road users that come with supersized trucks and SUVs. If your budget limits you to a smaller car, stepping up even slightly in size β e.g., from a subcompact to a midsize sedan β makes a meaningful difference.

2. SUVs Are No Longer the Threat They Once Were
For years, SUVs and pickups posed an outsized danger to people in smaller cars because their bumpers and energy-absorbing structures were higher than those of cars. In a collision, the larger vehicle would ride up over the hood of the smaller car, bypassing its crumple zone entirely.
Beginning in 2009, automakers redesigned front-end structures so SUVs and cars line up better. The results are dramatic:
car vs. SUV collision
from SUVs vs. cars
β οΈ Pickups still lag behind. In 2017β22, pickups were still nearly twice as likely to kill the driver of a car they crashed into, compared with car-on-car collisions (Monfort, 2025). Much of this is now attributable to their sheer weight, since structural alignment has improved.
What this means for you: If you're deciding between a midsize SUV and a sedan, the SUV is no longer a significantly greater threat to others than the sedan β a concern you may have heard about from older data. The bigger concern today is oversized pickups and trucks. See how different vehicles endanger others β
3. What the 2023 Fatality Data Actually Shows
Driver death rates per million registered vehicles (1β3 year old vehicles, 2023 FARS data).
| Vehicle Type | Single-Vehicle deaths per million |
Multiple-Vehicle deaths per million |
Total deaths per million |
|---|---|---|---|
| Cars | 23 | 43 | 66 |
| Pickups | 15 | 20 | 35 |
| SUVs | 11 | 14 | 25 |
Source: IIHS Fatality Facts 2023 β Passenger Vehicle Occupants. Rates reflect 1β3 year old vehicles to minimize the effects of vehicle aging.
Key takeaway: SUVs have the lowest driver death rates in both single-vehicle and multiple-vehicle crashes. Cars have nearly 3Γ the death rate of SUVs. This gap is driven by differences in weight, ride height, and structural design β reinforcing why stepping up from a compact car to a midsize SUV can be life-saving.
However, these rates also reflect driver demographics. Smaller cars tend to be driven by younger, less experienced drivers, which inflates their death rates. The vehicle itself is only part of the equation.
4. Prioritize Electronic Stability Control (ESC)
When shopping for older, budget-friendly used cars, Electronic Stability Control (ESC) is the single most important safety feature to look for after seatbelts. It helps prevent the loss of control that leads to rollover crashes β which accounted for 28% of all passenger vehicle occupant deaths in 2023 (IIHS).
ESC became mandatory in the U.S. for all vehicles manufactured after 2011, but many models introduced it years earlier. If you are buying a car built between 2005 and 2011, explicitly check if it has ESC (sometimes called VSC, StabiliTrak, or AdvanceTrac).
5. Look for "Good" IIHS Ratings β But Buy Newer
The Insurance Institute for Highway Safety (IIHS) routinely introduces harder crash tests. A car that earned a "Top Safety Pick" in 2010 would likely fail miserably if tested against 2026 standards.
Since 1978, death rates have declined dramatically across all vehicle types thanks to structural improvements, better airbags, and electronic safety aids. The newer the vehicle, the more likely it incorporates these advances.
The takeaway: Buy the newest vehicle you can comfortably afford, even if it means stepping down in luxury. A 2018 Honda Civic provides far superior structural protection than a 2008 Mercedes-Benz S-Class.
6. EVs and Hybrids Have a Hidden Safety Edge
Heavy vehicles are safer for their occupants, but they also burn more fuel β unless the extra weight comes from batteries. The IIHS notes that electric and hybrid vehicles gain protective mass from their battery packs without the fuel-economy penalty.
A Toyota RAV4 Hybrid, for example, weighs about 200 lbs more than its gas-only counterpart β pushing it closer to the "sweet spot" weight range without any additional fuel cost. This makes used hybrids an especially smart budget pick for safety-conscious shoppers.
π‘ Pro tip: When comparing two similar vehicles, the hybrid or EV version will almost always be heavier β and therefore better protected β for the same footprint. This is one of the few cases where a safety upgrade is also a cost savings.
7. The Free Safety Upgrades Anyone Can Make
Improve Your Safety Without Buying a New Car
If you truly want to reduce your risk of dying in a car crash, the most effective measures cost absolutely nothing. Vehicle engineering can only do so much to compensate for human choices.
- Wear Your Seatbelt: Almost half of all motor vehicle fatalities involve unbuckled occupants. The most advanced airbags in the world are designed to work with a seatbelt, not replace it.
- Reduce Your Speed: Speeding reduces your reaction time and exponentially increases the kinetic energy that your car's structure must absorb in a crash.
- Never Drive Impaired: Alcohol and drugs remain massive contributors to fatal crashes.
- Avoid Risk Times: Driving late at night on weekends drastically increases your likelihood of encountering an impaired or drowsy driver.
