Whenever you travel in a car or any other vehicle, there are risks involved. With each passing year, however, vehicle designs include more safety features intended to keep you safe. But as of 2025, the average age of vehicles on U.S. roads had reached 12.8 years. That means millions of older cars on the road lack modern safety features. On top of that, the cumulative effects of wear and tear can increase the odds of failure for older vehicle components. Here’s everything you need to know about why older vehicles pose higher safety risks.
The Rapidly Aging U.S. Vehicle Fleet
Over the past decade, a perfect storm of circumstances has pushed the average age of cars on U.S. roads higher than ever. Rising new‑vehicle prices have made replacing an older car less attractive to buyers, and COVID‑era supply‑chain disruptions led to a massive spike in used‑car prices, too. As a result, countless Americans found themselves in a position where a new vehicle was unaffordable, and a slightly newer used vehicle was, too.
Financially, it often makes sense to hold on to an aging car as long as it continues running reliably. However, the older a vehicle gets, the further it falls from modern safety standards. Common features on new vehicles include crash‑avoidance systems, lane‑departure warnings, and adaptive cruise control. Plus, older cars often have substandard tires, brakes, and steering systems due to age‑related deterioration. Together, those factors make older vehicles far more likely to be involved in fatal accidents.
There are even statistics that make the increased risk plain. According to data collected by the National Highway Traffic Safety Administration, a vehicle over 18 years old is 71% more likely to be involved in a fatal accident. Vehicles between eight and 11 years old are 19% more likely. New vehicles, meanwhile, are only 10% likely to result in fatalities in a crash.
The Effects of Wear and Tear
When you operate a vehicle, predictability is important. As a driver, you get to know the feel and responsiveness of your car the longer you spend behind the wheel. As your vehicle ages, however, it may lose that predictability. Braking distances may lengthen, suspension characteristics may change, and steering linkages may loosen. All of that increases the risk of driver error, which could lead to a crash. And even if drivers adjust to the changing feel of their vehicle, a sudden component failure could lead to an unrecoverable steering situation.
Lack of Modern Safety Features
Another reason for elevated safety risks in older vehicles is a lack of modern safety features. Today’s vehicles often include driver, passenger, and side‑curtain airbags as standard equipment. Some even have airbags protecting rear‑seat passengers. Older vehicles may only have driver and passenger airbags, as mandated by law. New cars also feature LiDAR and camera systems that enable warning systems, collision avoidance, and even near‑autonomous driving. Those systems rely on real‑time feedback from the vehicle’s onboard computer, allowing them to detect and react to changes in operating conditions almost instantly.
Increased Risk of Catastrophic Failure
Older cars are also more prone to sudden, catastrophic failures, which often lead to accidents. Electrical systems can fail, causing engine stalls at high speeds. Engines may develop leaks that lead to fires. Worn tires and suspension systems can increase the risk of blowouts, leading to loss of vehicle control. Worst of all, an older vehicle may show no warning signs before experiencing such failures. That deprives drivers of the chance to exercise caution or have their vehicles proactively serviced. By the time they sense a problem, it’s often too late to avoid an accident.
Compromised Structural Integrity
There’s another type of vehicle wear that owners frequently fail to appreciate in their older vehicles: rust. Most cars feature alloys that resist rust and may even have anti‑rust treatments in critical spots. However, none of those safeguards lasts forever, and designers don’t plan for vehicles to operate continuously for more than a decade or so. That can lead to significant accident risk in an aging vehicle. Rusted frame components can fail during a crash, leading to severe passenger injuries. Brake lines can rupture due to corrosion, creating a sudden loss of braking power. These risks are even higher in vehicles operated in colder climates, where frequent road salt use accelerates corrosion.
Incompatibility With Modern Roads
As odd as it sounds, an older vehicle can become a safety risk simply due to changes in roads and their usage. For example, today’s highways have denser traffic operating at higher average speeds than they did a decade ago. Older cars feature designs intended to provide reliable performance in road conditions that no longer exist. That makes them less capable of safely executing sudden maneuvers that today’s traffic patterns may demand. Older cars also feature outdated headlight designs that may be inadequate given recent changes in highway lighting.
Maintenance Difficulty and Neglect
The final major factor contributing to elevated safety risk in older vehicles is their growing maintenance difficulty. As cars age, dealerships and independent shops become less able to maintain them. OEM parts become scarce, leading to the use of aftermarket components with questionable durability. Plus, the increasing frequency of maintenance needs in older vehicles often stretches their owners’ budgets. That often leads to delayed repairs and neglected maintenance. All of those factors can accelerate the effects of the other risks associated with aging vehicles.
The Takeaway
The bottom line is that older vehicles pose substantially higher safety risks than newer models. The available statistics bear that out clearly, and the reasons for the elevated risks are well known. It’s also important to remember that the safety risks of older cars aren’t just an issue for their owners. Even if you’re driving a new vehicle, most of the people you share the road with aren’t. That means your new vehicle may get caught up in an accident caused by an older car. If that happens, it’s important to consult a car accident lawyer like the experienced attorneys at Thomas Law Offices to determine your rights and to see whether the other driver’s vehicle condition creates any additional liability. And if you do own an older car, it’s critical to address its safety issues before you end up injured or injure someone else.
