Why a Hands Free Device May Still Distract Drivers

Think your hands free device makes it safer to use your cell phone while driving? Think again. As it turns out, hands free devices can still be a distraction, and although handsfree is still better than handheld, both can lead to distracted driving.

Cell phone use is just one of many culprits that lead to distracted driving, but in recent years, it has contributed to a growing number of crashes. According to the National Safety Council, distracted driving kills 9 people and causes more than 1,000 crashes every day, making distracted driving a serious problem. While hands free is better than handheld, both are still distracting. That’s largely because of the limitations of the human brain: our brains simply can’t do everything we may expect of them at the same time.

Why a Hands Free Device May Not Make You Safer

Car Bluetooth devices are commonplace for most drivers, which means there’s less reason to use a handheld device while driving. The use of handheld devices while driving limits a driver’s ability to operate a vehicle properly, but do Bluetooth devices solve that issue? Recent research shows that having your hands free isn’t the only thing that matters for safety. It’s equally important to have your mind free of distractions while driving.

study published by the University of Sussex in England found that talking on the phone, even with a hands free device, requires much of the same brain processing resources needed for driving. Doing both at the same time caused participants in the study to detect fewer hazards, respond to hazards more slowly and fail to register seeing things that were right in front of them.

Focus & Hands Free Devices While Driving

If you’ve ever been irritated by a family member who appears to tune out your voice while reading the newspaper or attend to a crying grandchild, you may be surprised to learn that they may not be purposefully ignoring you. Instead, their brain may be unable to pay attention to what you’re saying while focused on the newspaper or a small child’s whines. That’s because our brains aren’t the best at multitasking. You need a certain amount of focus for every task, and that focus may not go as far as you think.

Through extensive study, researchers have found that attention is a limited resource. Each person only has a certain amount of attention available, and when focusing his or her attention on one thing, he or she is unable to focus on others. Nobody can attend to everything at once, so when we apply our attention resources to one thing, we are always doing so at the expense of other things.

Our senses have some attention resources, but they can also interfere with each other. For instance, if you’re looking at something (paying attention to a visual task), you may be able to listen to something else (paying attention to an auditory task) more easily than you could focus on looking at something else. That’s why you may feel like you can pay attention to the road in front of you while talking on a cell phone, but not while looking at your navigation system. However, attention to one sense, such as hearing, can impair attention to another, such as vision, says attention researcher Marc Green, Ph.D

A Hands Free Device for Your Car May Not Get Rid of Distractions

If you think having a hands free device for your car gets rid of distractions, you could be mistaken. It all comes down to the way the brain processes information. The human brain has a limited capacity to process visual images simultaneously. Although talking on the phone may seem like it would only require auditory resources—the sense of hearing—it uses up the brain’s visual processing abilities as well. Psychological researchers at The University of Sussex discovered found that talking on the phone – even when it’s handsfree – uses more of the brain’s visual resources than was previously understood.

That’s because when you’re in a conversation, your brain is visualizing what you’re talking about. Someone on the other end of the phone line may ask, “Where did you put the green folder?”  This question might cause you to visually imagine the green folder, the room the green folder was in, what the green folder was used for, and several other visual things.

Research shows that a brain does not have enough processing ability to simultaneously imagine images and keep track of what the eyes are seeing, which is a knock against the use of hands free devices while driving. For instance, you may see the trash receptacle in your lane, but because your brain is focused on an intense phone conversation, your brain may not actually register the receptacle until you’re too close to avoid it. Even worse, your brain could be busy processing your phone conversation and the emotions stemmed from it, causing road rage in some cases. This ultimately can contribute to you driving a little faster and cause you to miss the vehicle pulling out into your lane or the child running into the street from your right.

“Conversations are more visual than we might expect, leading drivers to ignore parts of the outside world in favor of their inner visual world, with concerning implications for road safety,” says Graham Hole, a senior lecturer in psychology at the University of Sussex and one of the study’s authors.

By tracking eye movements, the Sussex study found that distracted drivers suffered from “visual tunneling,” which means they tended to focus their eyes on a small, central region directly ahead of them. This type of tunneling led participants to miss hazards in their peripheral vision.

These findings signify dangerous consequences for drivers who use their cell phones, even those that are using a hands free device. While hands free devices are significantly safer than a handheld device, they are still problematic and unsafe.  “The only safe phone in a car is one that’s switched off,” Hole says. This will ultimately prevent distracted driving leading to car crashes and other accidents.

For parents of young drivers, it’s important to try and instill habits of distraction-free driving in kids right from the beginning. Try to encourage making the car a phone shutdown zone. Or, if turning off the phone isn’t an option, encourage them to put their device in airplane mode, which essentially turns off the device’s ability to receive calls and texts. There are also ways that parents can monitor their teen’s driving with different apps and devices. For more tips, see our teen driver advice article.  

Are You Breaking the Law?

When you use your cell phone behind the wheel, you’re not just endangering yourself, your passengers and others; you may also be breaking the law. That means you could risk getting a ticket or worse, a criminal charge in the case of an accident. Putting down the device can also save you an increase in your insurance premium, as distracted driving can impact your premium.

number of states have passed legislation banning some types of cell phone use. Fourteen states and the District of Columbia ban handheld cell phone use while driving. No state bans all cell phone use while driving, but 38 states and D.C. do ban all cell phone use by novice drivers, such as those under a certain age or newly licensed. Twenty states also ban all cell phone use for school bus drivers. Texting while driving is almost universally banned: 46 states and D.C. prohibit text messaging for all drivers. While using a handsfree, Bluetooth car device is legal, it should still be treated with extreme caution.

Stay Safe with Hands Free Devices While Driving by Not Using Them

According to the National Safety Council, there are three basic requirements for staying safe while driving: keep your eyes on the road, hands on the wheel and your mind on driving. While practicing these, the number of auto claims will decrease due to distracted driving.

When using a cell phone, whether through hands free devices or handheld, it’s almost impossible to abide by those three requirements. You can help keep yourself, your passengers and others safe by waiting to use your device until you’ve stopped the car.

While it may be tempting to use a hands free device in your car, keep in mind that doing so may jeopardize your own, or someone else’s, safety.

Alternatives to Distracted Driving

Never text in a car. If you must send a text, ask if a passenger can send it for you. Or, if it’s urgent, you might be able to use voice control to send a text, if your car has that functionality. Do not pick up your phone to activate voice text. None of these methods are full proof. If you really need to use your phone, the best way is to pull over, stop the car, and use the phone then.

Use a location-sharing app if you’re planning on meeting your friends for a time-sensitive activity. Some apps will allow you to share your location with friends; that way you won’t have to text your friends if you’re late or stuck in traffic.

Take the Pledge

It’s important to understand the ways to prevent distracted driving. That’s why the National Safety Council established a pledge to try and educate and encourage drivers to avoid distractions while driving. The pledge outlines the different distractions that affect drivers. Distractions listed include:

  • Having a phone conversation – handheld, handsfree, or via Bluetooth
  • Texting or sending Snapchats
  • Using voice-to-text features in my vehicle’s dashboard system
  • Updating Facebook, Twitter, Instagram, Vimeo or other social media
  • Checking or sending emails
  • Taking selfies or filming videos
  • Inputting destinations into GPS (while the vehicle is in motion)
  • Calling or messaging someone else when I know they are driving

  • I have a phone in my truck most of the time it's for emergency's,but when I am out and I have been gone all day I will call home to let my husband know where I am on my way.

    I love having it that way because my hands are free and I can still concentrate on what I am doing, I do think that's the best way to be on the phone IF you have to.

  • Biggest problem I see on the road are drivers that are looking down in their laps on their phones.. That and the fact a high number of people follow too closely to the traffic ahead of the them... It pays to stay far enough away from the traffic ahead of you, that way you will be able to safely stop even though someone is tailgating you.

  • Put your cell phone in "air plane mode" when driving. Simple as that.
    Live's are at stake,and not just yours. Just "Stop It"!

  • We seem to forget that driving is a privilege, not a right. A car is a seriuos killing machine when not being driven with complete focus, mindfulness of other drivers. Eyes lookinf at the road ahead, checking all mirriors,(side and rear view). Hands at 2 and 10 on the steering wheel.
    May I also add the number od drivers accelerating through RED lights , running them with total disregaurd!
    My anxiety level continues to elevate as each day goes by.

    Car companies, take all your tech devices out and put them back in homes where they belong.Our cars are not family rooms on wheels, unless perhaps you are traveling in an RV as a passenger.

    I just want to stay home anymore. It's a war out there on the interstate's, highways and just even driving through ones neighborhood. Parking lots are like the wild. wild west. I hate them!!!

  • There are individuals I believe capable of using hands-free and some not so capable. That being said, I think hands free only should be allowed. Debates can go on forever on this subject. I would like to hear that more people were getting stopped for cell phone usage (not hands free). I pass quite a few people on their phones going under the speed limit, drifting close to the other lane because they are leaning on their elbows while talking. Insurance companies need to cover damages to vehicles. Cost of insurance is not always affordable but a person hit by a driver texting should be able to receive cost of damages. I have also driven by a woman reading a book across her steering wheel, people reaching into back seats. There should be a non emergency number to call to report these people!

  • I was a professional driver for over 15 years and I can absolutely say with 100% certainty that using a hands free device is no different than talking with a passenger in your car! I was always against cell phone use while driving and I still am, but that requires physical interaction and hands free does not. Any person that can't drive and talk to someone should never be issued a license. Every driving instructor talks to their student during the lesson. How do explain that?

    • Hi Rick, we’re sorry to hear you’re cancelling. Please call our Customer Service Center at 1-800-423-6789 and one of our representatives can cancel your policy for you. Thank you!

  • I've always always said hands-free doesn't make any difference you should be on a cell phone at all when you're driving
