- Safety features discounts are real but vary by insurer — not every company offers every discount and some states require insurers to offer discounts for specific features like anti-lock brakes.
- Airbags and ABS are the most universally discounted features — most major insurers offer rate reductions for these, applied to medical payments, PIP and sometimes liability coverage.
- Anti-theft devices reduce your comprehensive premium — the more sophisticated the device (from audible alarm to GPS recovery system), the larger the discount.
- Your car’s trim level matters — two versions of the same model can have very different safety packages and insurers rate them differently. Using your VIN when quoting ensures the right features are captured.
- Modern ADAS features are increasingly earning discounts — automatic emergency braking, lane departure warning and forward collision alert are now recognized by a growing number of insurers.
Which car safety features lower your insurance rates?
Yes; car insurance companies offer discounts for a range of factory-installed safety features. The savings are real, though the exact discount depends on your insurer, your state and your vehicle’s specific features.
Insurance companies price policies based on risk. A car with more safety features poses a lower risk of injury and accident claims, which translates to lower rates. Some states — including Florida, New Jersey and New York — require insurers to offer discounts for specific features like anti-lock brakes. In other states, discounts are offered at the insurer’s discretion.
The key thing to understand: Not all features are discounted the same way and the discount is often applied to a specific coverage type rather than your total premium. Knowing which features you have — and asking your insurer to verify them — is how you make sure you’re getting every dollar of savings you’re entitled to.
Which car safety features qualify for an insurance discount?
The following features are the most widely recognized across major insurers. Discount ranges are approximate and vary by company and state. See a table with common safety features and their associated discounts in the table below.
| Safety feature | Coverage(s) typically affected | How it works | Notes |
|---|---|---|---|
| Airbags | Medical payments, PIP, sometimes liability | Discount increases with number of airbags; dual front + side airbags earn more than front-only | One of the most universally offered safety discounts |
| Anti-lock brakes (ABS) | Liability, PIP, medical payments, collision | Prevents wheel lockup during hard braking, reducing accident severity | Required discount in FL, NJ, NY; voluntary in most other states |
| Electronic stability control (ESC) | Collision | Factory-installed ESC reduces rollover and loss-of-control risk | Must be factory-installed; aftermarket systems may not qualify |
| Automatic seat belt/ seat belt use | PIP, medical payments | Some insurers discount for automatic seat belts or documented seat belt use by all occupants | Less common than other discounts |
| Daytime running lights | Liability, PIP, medical payments, collision | Reduces risk of being struck by other vehicles in low-visibility conditions | Offered by some but not all insurers |
| Crash-resistant doors | Collision | Reinforced door construction reduces side-impact claim costs | Less common; check your insurer’s full discount list |
| Anti-theft system | Comprehensive | Tiered by sophistication — passive alarm < active alarm < GPS recovery (e.g., LoJack) | Stacking multiple anti-theft devices increases the discount |
| VIN etching | Comprehensive | Etching your VIN on windows deters theft by making parts harder to sell | Available as a standalone discount from some insurers |
A note on how these discounts stack: Many of the discounts above apply to different portions of your policy. A car with dual airbags, ABS and a LoJack system could net three separate discounts across PIP, collision and comprehensive coverages. Ask your insurer to review all applicable discounts in a single call.
Do modern driver assistance features (ADAS) qualify for discounts?
This is where the landscape is changing fastest. For years, insurers were cautious about discounting advanced driver assistance systems (ADAS) — technologies like automatic emergency braking (AEB), lane departure warning, adaptive cruise control and blind spot monitoring — because there wasn’t enough claims data to quantify the risk reduction.
The Insurance Institute for Highway Safety (IIHS) and the National Highway Traffic Safety Administration (NHTSA) have both documented significant crash reduction benefits from AEB and lane keeping assist. As that data has accumulated, more insurers have begun incorporating ADAS features into their rating algorithms — either as named discounts or as factors in how they score the vehicle model overall.
Even when an insurer doesn’t offer a specific named “ADAS discount,” having these features on your vehicle tends to lower your rates indirectly: car models with fewer injury and accident claims get better base rates and ADAS-equipped vehicles consistently show fewer claims.
Sophie’s tipIf your car has any of these features, mention them specifically when quoting or renewing — don’t assume your insurer has already factored them in.

How does your car’s trim level affect safety feature discounts?
Two versions of the same car model can qualify for very different discounts depending on the trim level. A base trim may come with front airbags only, while a mid- or top-tier trim may include side curtain airbags, ABS, ESC and a factory-installed backup camera. Each of those additional features is a potential discount.
This is why entering your VIN (Vehicle Identification Number) when getting a car insurance quote is more accurate than just selecting the make, model and year. Your VIN encodes your car’s exact specifications — including every factory-installed safety feature. Most major online quoting systems accept VIN input and will automatically pull your car’s feature profile.
If you’re shopping for a new car and comparing insurance costs between trim levels, this is worth factoring into the total cost of ownership calculation. A trim with more safety features may cost more upfront but could earn enough in ongoing insurance discounts to offset part of that difference over time.
If you’re already insured, call your insurer and ask them to verify which safety features are recorded on your policy. Insurers occasionally miss features — especially on vehicles purchased used — and you may be entitled to discounts that aren’t currently being applied.
Which coverages do safety feature discounts apply to?
One of the more confusing aspects of safety feature discounts is that they’re not applied to your total premium as a single line item. Each discount typically applies to a specific coverage type:
Medical payments and PIP (Personal Injury Protection): Airbags and seat belt discounts are most commonly applied here. These coverages pay for injury costs to you and your passengers — features that reduce injury severity directly lower insurer risk in this category.
Collision coverage: Anti-lock brakes, electronic stability control and crash-resistant doors are most commonly discounted here. These features reduce the likelihood or severity of collision claims.
Comprehensive coverage: Anti-theft systems and VIN etching discounts are applied to comprehensive coverage, which pays out for theft and non-collision damage.
Liability coverage: Some insurers extend ABS and daytime running light discounts to the liability portion of your policy, reflecting the reduced risk of causing accidents that harm other people or their property.
Because discounts apply to different coverage types, the total dollar impact depends on your coverage mix. A driver carrying state minimum liability only won’t benefit from a collision discount on ABS. A driver with full coverage benefits across multiple lines.
How do you make sure your insurer knows about your car’s safety features?
Most drivers leave safety feature discounts on the table simply because they never confirmed that their insurer has the correct information. Here’s how to claim every discount you’re entitled to:
Ask about stacking discounts. Safety feature discounts can often be combined with safe driver discounts, telematics/usage-based discounts and bundling discounts. Ask your agent whether these stack or whether there’s a cap.
Look up your car’s features via VIN. Your car’s VIN can be decoded at the NHTSA’s VIN decoder or through your vehicle manufacturer’s website. This gives you a complete list of factory-installed features to reference.
Call your insurer and ask specifically. Don’t ask “am I getting all my discounts?” Ask specifically: “Does my policy reflect a discount for [feature]?” Go through the list: airbags, ABS, ESC, anti-theft, ADAS features. Ask to which coverages each discount applies.
Request a policy review when buying a new car. Any time you replace or add a vehicle, ask your insurer to do a full discount review based on the new vehicle’s features.
Compare quotes using your VIN. When shopping for a new policy, input your VIN directly rather than selecting by make/model/year. This ensures any comparison quote reflects your car’s actual safety profile.
FAQs: Car safety features and insurance discounts
Which car safety features give you the biggest insurance discount?
Airbags and anti-lock brakes are typically the most widely discounted features, with airbag discounts applied to medical/PIP coverage and ABS discounts applied to collision. Anti-theft devices can also generate meaningful, comprehensive coverage discounts.
Do anti-lock brakes lower car insurance rates?
Yes. Anti-lock brakes (ABS) lower car insurance rates in most states. ABS discounts are most commonly applied to liability, PIP, medical payments and collision coverage portions of your policy.
Does automatic emergency braking lower insurance rates?
Increasingly yes, though it varies by insurer. As NHTSA and IIHS claims data has accumulated showing that AEB reduces rear-end crashes, more insurers have incorporated it into their rating models. Even when an insurer doesn’t offer a specific named discount, AEB-equipped vehicles tend to have lower base rates due to better overall claims performance.
Can you stack safety feature discounts with other car insurance discounts?
Yes, in most cases. Safety feature discounts apply to specific coverage types (airbag discount on PIP, ABS discount on collision, etc.) and typically stack independently with driver-based discounts like safe driver, good student, or telematics/usage-based discounts. Ask your insurer to confirm whether there’s a maximum discount cap on your policy.
How does your VIN help you get safety feature discounts?
Your Vehicle Identification Number (VIN) encodes your car’s exact factory-installed specifications, including every safety feature. Entering your VIN when getting a quote — rather than just selecting make, model and year — ensures the quoting system captures all your features.
