The U.S. Census Bureau predicts that the number of drivers 65 years and older will more than double in the next 40 years. That means that U.S. roads may be facing a safety crisis in the future, as older drivers tend to cause higher accident rates than others.

As a driver matures, their vehicle needs become different as well. It's unlikely that older drivers will be opting for a sports car, for example. According to Consumer Reports, there are a number of vehicle features that may be beneficial to older drivers looking to purchase a vehicle that may help them be safe on the road.

One of the considerations cited by the news source is ease of access. A vehicle for older drivers needs to have a number of seat configurations and ways to enter the vehicle that will make comfort a priority. A full-size SUV or pickup truck simply isn't practical for drivers with back problems, for example. Power seats are also preferable to those with a manual system, as they can be adjusted at the touch of a button.

Safety is another top priority that older drivers should consider, especially if they'll be traveling with grandkids or other family members. The vehicles chosen by the news source all have average or better reliability and perform well in government and insurance company crash tests.

Vehicles with full airbags, including side curtain, can greatly increase the protection afforded in case of a crash. The news source also notes that electronic stability control (ESC) is a must for any driver, but thankfully all vehicles made after 2012 will have this feature. Those buying a used car should be sure that their model is equipped with ESC.

Finally, one of the most important yet overlooked aspects of cars for elderly drivers is vision. Some vehicles contain numerous blind spots or even issues with the visor angle that can increase glare. In addition, the news source specified looking for a vehicle with a larger instrument panel that is easy to read.

In terms of cars that fit these requirements, the news source recommended the Hyundai Azera, Kia Rondo, Subaru Forester, and Honda's Accord sedan and Odyssey minivan.

Drivers interested in purchasing one of these vehicles may want to shop the used car market, where they can likely find them for less than new car dealerships.
