There are multiple key safety options on vehicles these days — here's how they work to protect all riders.

It’s been a quarter century since airbags became mandatory in new cars and light trucks sold in the United States. Frontal airbags alone have been credited with saving more than 50,000 lives, the National Highway Traffic Safety Administration says.

But the engineers behind automotive design didn’t stop there. As technology has advanced, so have safety features. And that’s good news for older drivers, says Josh Dunning, an AARP vice president and national director of AARP Driver Safety. “Technology in vehicles has significantly improved safety over the years and when used properly can offer strong additional protection,” he says.

Here are key safety features industry professionals say you should consider.

Forward collision warning

Your car can detect another car or other obstacle ahead. When it senses the threat of a crash, based on speed and distance, it alerts you with a warning sound, visual alert, steering wheel vibration or brake pulse. “We’ve seen it reduce crashes by about a quarter,” says Jessica Cicchino, vice president for research at the Insurance Institute of Highway Safety.

Automatic emergency braking

This takes things a step further, not only detecting that you need to brake, but doing it for you. “It’s that extra bit of protection when perhaps you’re not seeing that person up ahead,” says Pam Shadel Fischer, senior director of external engagement with the Governors Highway Safety Association. Automatic reverse braking is also an option in some vehicles, says Daniel McGehee, director of the Driving Safety Research Institute at the University of Iowa. “Bumpers are expensive now,” he says. “If you even bump backwards into a pole, it’s going to cost around $3,000 to $4,000 to fix.”

Blind spot warning

This alerts you to a potential crash when changing lanes, but it takes different forms. “Ideally, you need more than just having a light on your instrument display,” says Kennerly Digges, head of the Automotive Safety Research Institute. “You need to have the wheel shake.” Cicchino says this safety feature can be especially important as we age. “Lane-change crashes are more common with older drivers. Older people might have trouble turning to check their blind spot or being able to judge traffic and spaces.”

Lane-keeping assist

This is more than just a warning light; in the best of these systems, your car gently tugs the wheel when it detects you’re drifting into another lane. “Many crashes are the result of running off the road,” Shadel Fischer says. “That’s especially true in rural areas. Lane-keeping assist gives people a nudge to get back in your lane.”

Driver monitoring systems

These systems, which detect if you aren’t keeping your eyes on the road, are becoming more common. Some can also detect if you’re becoming drowsy and warn you to take a break. “It’s a pretty simple technology,” McGehee says. “It looks at head pose; a few look at eyes as well. I would say if it’s available, I would get it.”

Traffic sign recognition

With this advanced tech, your car sees a sign, such as speed limit or yield, and displays the information on your dash. “As we get more comfortable driving, our speeds tend to go up,” Shadel Fischer says. “It’s nice to have that visual reminder that this is the speed limit for this road.”

Adaptive headlights

Unlike traditional headlights that are fixed in a single direction, adaptive headlights can sense which way you’re turning and focus the light where you’re headed. “They help illuminate the road ahead around some curves,” McGehee says.

Rear occupant alert

This senses when a passenger is still in the car and gives you a warning, especially important when transporting kids. “We have lost children because the driver was distracted and walked away and the child was left in a hot car,” Shadel Fischer says.

Front-center airbags

Digges says that having an airbag that inflates between you and your passenger is crucial. “The bottom line is that crashes come from all sides, and you need to have protection from all directions.”
