Safety Features That Lower Car Insurance (and the Coverage Each One Affects)

Often yes, though modestly. The Texas Department of Insurance names airbags, antilock brakes, and antitheft devices among the things that might earn you a discount, and it adds the detail that matters most: each company decides which discounts to offer and how large they are. Safety feature discounts are also attached to particular coverages rather than the whole premium, so an airbag discount reduces the injury portion of your bill and an anti-theft discount reduces only comprehensive. The savings are real, but they are a slice of a slice, and the feature you had in mind may already be built into your rate.

Which feature affects which coverage

A discount follows the risk the feature reduces. Florida's insurance statute is the clearest public example of that mapping, because it writes the connection out. Under Florida law, rate filings for liability, personal injury protection, and collision coverage must include a premium discount when the insured vehicle has factory-installed four-wheel antilock brakes. Rate filings for personal injury protection and medical payments coverage must include a discount when the vehicle has one or more factory-installed air bags. And every insurer selling comprehensive coverage in Florida must include comprehensive discount provisions for an anti-theft device or vehicle recovery system that is factory installed or approved by the state. Those are Florida's rules, but they reflect how insurers elsewhere tend to categorize these discounts.

• Air bags and other passive restraints: discounts on injury coverages such as personal injury protection and medical payments
• Anti-lock brakes: discounts on liability and collision, the coverages that respond when a crash is not avoided
• Anti-theft devices and recovery systems: discounts on comprehensive alone, the coverage that pays when the car is stolen
• Collision-avoidance and automated driving systems: Florida law permits, but does not require, discounts on liability, personal injury protection, and collision for factory-installed or retrofitted systems that meet federal standards

Why the savings are smaller than they sound

A discount tied to one coverage cannot reduce the others. If liability makes up most of your premium, an anti-theft discount on comprehensive hardly changes the total. The reverse holds too: if you carry liability only, an airbag discount aimed at medical payments has nothing to attach to.

Factory features are also frequently priced into the base rate before any discount is applied. Insurers know your car's year, make, and model, and that vehicle's own history of injury and theft claims already shapes the starting price. Asking for the discount is still worthwhile, because a line item on your declarations page is easier to verify than a rate class, but do not expect a large reduction on a car whose safety record is already reflected in the base rate.

Newer driver-assistance features are the least settled. Whether automatic emergency braking or lane keeping earns its own line-item discount depends on the insurer, and some states, Florida among them, allow such discounts without requiring them. The only way to find out is to ask your company what it does with those features, and to put the same question to any other insurer you price the policy with.

How to make sure you get credit

The Texas Department of Insurance's advice about its safe car discount applies to every feature on this list: if you have anti-theft devices, or add them after buying a policy, tell your company. Factory equipment is usually identified from the vehicle identification number, but aftermarket equipment stays invisible to the insurer until you report it.

• Write down the safety and security equipment on the car, using the window sticker or owner's manual, before you call
• Ask your insurer for an itemized list of every discount currently on the policy and which coverage each one reduces
• Report aftermarket equipment such as an alarm, immobilizer, or tracking device, and keep the installation receipt
• Ask again at renewal and whenever you price the policy elsewhere, since the Texas Department of Insurance notes that each company sets its own discounts and amounts

The discounts that actually change the bill

Safety features are a bonus, not a plan. The Texas Department of Insurance's list of possible discounts also includes completing a defensive driving or driver education course, insuring more than one car on a policy, holding other policies with the same company, and having no claims and a good driving record. Its money-saving tips add good driver, low-mileage, and good student discounts. Those apply to bigger portions of the premium, and a clean record or a higher deductible usually does more than any single piece of equipment.

The bottom line: airbags, anti-lock brakes, and anti-theft devices can lower car insurance, but only on the coverage each one affects and only by the amount your company chooses. Tell your insurer what the car has, get the discounts itemized, and then focus on the driving record and renewal habits that move the entire bill.
