What makes an SUV safer for families

The safest SUV for your family depends on crash test results, the size of your children, how often you drive on highways versus city streets, and whether you prioritize protection in frontal collisions, side impacts, or rollovers. There is no single "safest" model across all scenarios — a three-row SUV that protects well in side crashes may handle differently than a compact model, and both perform differently depending on what hits them.

The National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS) publish crash test ratings that let you compare specific models year by year. NHTSA rates vehicles on a five-star scale for frontal crashes, side crashes, and rollover resistance. IIHS conducts additional tests including small-overlap frontal crashes and crash avoidance technology. Both organizations update their ratings annually, so a 2024 model may have different results than a 2023 version of the same nameplate.

Beyond crash protection, the safest family SUVs typically include features like automatic emergency braking, blind-spot monitoring, and rear-seat reminders for child passengers. Some of these are now standard on most new vehicles; others remain optional. Your insurance company may offer discounts for certain safety features, which can offset the cost of upgrading to a model with more advanced technology.

Key Takeaways

  • NHTSA and IIHS publish free crash test ratings for every SUV model and year, and you should compare ratings for the specific year and trim you are considering, not just the model name.
  • Frontal crash protection, side crash protection, and rollover resistance are tested separately, so an SUV that scores well in one category may not score as well in another.
  • Automatic emergency braking and blind-spot monitoring reduce the likelihood of a crash occurring in the first place, not just the severity if one does.
  • Larger SUVs offer more protection in crashes with smaller vehicles but may be harder to maneuver and have larger blind spots, which creates different risks for families with young children.
  • Used SUVs from recent model years often cost less than new ones but may lack the latest safety technology, so compare what features are actually included in the year and trim you are buying.

How to read NHTSA and IIHS crash test ratings

NHTSA rates vehicles on a scale of one to five stars in three categories: frontal crash, side crash, and rollover. A five-star rating means the vehicle performed better than 90 percent of vehicles tested; a one-star rating means it performed worse than 90 percent. The overall rating is the lowest of the three scores, so a vehicle with five stars in frontal and side crashes but three stars in rollover gets an overall three-star rating.

IIHS uses a different scale: Good, Acceptable, Marginal, or Poor. They test small-overlap frontal crashes (which NHTSA does not), moderate-overlap frontal crashes, side crashes, roof strength, and seat and head restraint effectiveness. IIHS also rates crash avoidance and mitigation technology separately. A vehicle can earn the IIHS Top Safety Pick award only if it scores Good in all crashworthiness tests and has superior or advanced crash avoidance technology.

To find ratings for a specific SUV, visit safercar.gov (NHTSA) or the IIHS website (iihs.org). Enter the model year, make, and model. Both sites let you compare two vehicles side by side. Print or save the results before you visit a dealership, because salespeople often cite only the ratings that favor their inventory.

Frontal, side, and rollover protection compared

Frontal crashes are the most common type of serious crash, and they account for roughly 40 percent of traffic fatalities. NHTSA tests frontal crashes at 35 miles per hour into a fixed barrier; IIHS tests at 40 miles per hour and also conducts a small-overlap test at 40 miles per hour where only 25 percent of the vehicle's front end hits the barrier. Small-overlap crashes are harder to protect against because the engine and frame do not absorb as much energy.

Side crashes are less common but often more severe because there is less metal between the passenger and the other vehicle. NHTSA tests side crashes at 38.5 miles per hour with a moving barrier that simulates a vehicle hitting the side of the test vehicle. IIHS uses a similar test. Side crash protection depends heavily on the strength of the door frame and the quality of side-impact airbags, which vary significantly between models.

Rollover resistance is measured differently than crash tests. NHTSA calculates a rollover rating based on the vehicle's center of gravity, track width, and wheelbase — taller, narrower vehicles with shorter wheelbases are more prone to rolling. Actual rollover crashes are less common than frontal or side crashes, but they are more likely to result in fatalities. Three-row SUVs are generally more stable than compact crossovers because they sit lower and have a wider stance.

Safety features that prevent crashes before they happen

Automatic emergency braking (AEB) detects an obstacle or another vehicle ahead and applies the brakes if the driver does not respond in time. Studies show AEB reduces rear-end crashes by 40 to 50 percent. IIHS rates AEB as Superior, Advanced, or Basic depending on how well it works at different speeds and in different lighting conditions. Many insurance companies offer discounts of 5 to 10 percent for vehicles with Superior AEB.

Blind-spot monitoring uses radar or cameras to detect vehicles in the driver's blind spots and alerts the driver with a light or sound. Rear cross-traffic alert warns you when a vehicle is approaching from the side while you are backing up — this is especially useful in parking lots and driveways where children may be present. Neither feature is standard on all SUVs, so check the window sticker or owner's manual to confirm what is included in the trim you are considering.

Lane-keeping information gently steers the vehicle back into its lane if it drifts without signaling. Adaptive cruise control maintains a set distance from the vehicle ahead and slows down automatically if traffic slows. These features reduce driver fatigue on long highway trips and lower the risk of single-vehicle crashes. They are increasingly common on mid-range and higher trims but may not be standard on base models.

Size and weight trade-offs in family SUVs

Larger SUVs offer more protection in crashes with smaller vehicles because they weigh more and sit higher, which means the force of impact is distributed differently. In a crash between a full-size SUV and a compact sedan, the SUV's occupants typically experience less deceleration and injury. However, larger SUVs are harder to maneuver, have larger blind spots, and are more prone to rollover if they swerve suddenly to avoid an obstacle.

Compact and mid-size SUVs are easier to park, have better visibility, and are less likely to roll over. They also cost less to buy and operate. In crashes with larger vehicles, they offer less protection, but in crashes with other compact vehicles or in single-vehicle accidents, the difference is smaller. For families with young children who spend most of their time in city driving and parking lots, a compact SUV with good crash test scores may be safer overall than a larger model that is harder to control.

Three-row SUVs are designed for families with three or more children or for those who frequently transport passengers. The third row is farther from the front of the vehicle, which means passengers there experience less force in a frontal crash. However, the third row has less crush space behind it, so side crashes and rear-end crashes pose greater risk. If you use the third row only occasionally, a two-row SUV may be a better choice.

Comparing new versus recent used SUVs for safety

New SUVs have the latest safety technology, including the most advanced versions of automatic emergency braking, blind-spot monitoring, and lane-keeping information. They also come with a warranty that covers defects in safety systems. However, new SUVs cost significantly more, and the safety benefit of the newest technology over a 2022 or 2023 model is often small in real-world crashes.

Used SUVs from the past three to five years typically have most of the safety features found on new models, especially if they are mid-range or higher trims. Check the window sticker or owner's manual to confirm what safety features are included, because base models may lack features that are standard on higher trims. A 2022 model with Superior automatic emergency braking and blind-spot monitoring may be safer in practice than a 2024 base model without those features.

Older used SUVs (2018 and earlier) may lack automatic emergency braking or have earlier versions that are less effective. If you are considering a used SUV older than five years, prioritize models with high NHTSA and IIHS crash test scores, because the safety technology gap becomes more significant. Have a pre-purchase inspection performed by an independent mechanic to confirm that airbags, seat belts, and other safety systems are functioning properly.

Where to find detailed safety information and ratings

NHTSA's safercar.gov website includes crash test videos, detailed ratings for each test, and a comparison tool. You can search by model year, make, and model, and the site shows you exactly how each vehicle performed in each test. NHTSA also publishes a list of vehicles with the highest safety ratings by class, updated annually.

The IIHS website (iihs.org) includes crash test videos, ratings for crash avoidance technology, and a list of Top Safety Pick winners. IIHS ratings are more stringent than NHTSA ratings, so a vehicle that earns a Top Safety Pick award has met a higher standard. The IIHS site also includes information about insurance claims data, which shows which vehicles have the lowest rates of injury claims in real-world crashes.

Your insurance company may have safety ratings or discounts available on their website. Some insurers partner with IIHS or conduct their own research. Call your agent and ask whether they offer discounts for specific safety features or models, because this can significantly reduce the cost of insuring a safer vehicle.

Frequently Asked Questions

Is a larger SUV always safer for a family than a smaller one?

No. A larger SUV offers more protection in crashes with smaller vehicles, but it is harder to control and more prone to rollover. A compact SUV with high crash test scores and good safety technology may be safer overall for a family that drives mostly in cities and parking lots. Compare crash test ratings for the specific models you are considering rather than assuming size alone determines safety.

What is the difference between NHTSA and IIHS ratings?

NHTSA uses a five-star scale and tests frontal crashes, side crashes, and rollover. IIHS uses a Good/Acceptable/Marginal/Poor scale and tests small-overlap frontal crashes, moderate-overlap frontal crashes, side crashes, roof strength, and crash avoidance technology. IIHS ratings are generally more stringent. Both are free and available online, and you should check both before buying.

Should I buy a new SUV or a recent used one for safety?

A recent used SUV (2021 or newer) with the right safety features may be as safe as a new one and costs significantly less. Check the window sticker to confirm it includes automatic emergency braking and blind-spot monitoring. If you are buying a used SUV older than five years, prioritize high crash test scores and have an independent mechanic inspect the safety systems before you buy.

Does automatic emergency braking really make a difference?

Yes. Studies show automatic emergency braking reduces rear-end crashes by 40 to 50 percent. It is especially useful for families because it can prevent crashes caused by driver distraction or fatigue. Many insurance companies offer discounts of 5 to 10 percent for vehicles with Superior-rated automatic emergency braking, which can offset the cost of choosing a model that includes it.

What safety features should I prioritize if I have young children?

Prioritize automatic emergency braking, blind-spot monitoring, and rear cross-traffic alert, because these reduce the risk of crashes in parking lots and driveways where children are most vulnerable. Also look for rear-seat reminders that alert you if a rear door was opened before the trip, which can prevent children from being left in the vehicle. Check crash test scores for side crashes, because children in rear seats are more vulnerable in side impacts.
