Do Hands-Free Devices Really Reduce Your Risk of Getting Into a Car Accident?

We may think these hands-free technologies are the safest way to stay connected, but the AAA Foundation is challenging this assumption. The study focused on research of mental distractions which can lead to suppressed brain activity and impaired driving performance as a result of performing cognitively-demanding tasks.

The study, conducted at the University of Utah, used a driving simulator, a combination of brainwave activity measures, driving performance indicators and other assessments to examine participants in a lab as they performed six common driving tasks. These tasks included listening to the radio, listening to a book on tape, conversing with a passenger, talking on a hand-held phone, talking on a hands-free phone, and interacting with a speech-to-text email system. Researchers then compiled the findings into a ranking scale to determine which activity ranked highest and lowest on mental distraction.

The findings from the study suggested that listening to the radio or a book while driving only create a small increase in cognitive distraction. Phone conversations, however, whether they were while using a hand-held or hands-free device, created significant levels of cognitive distraction. This was proven from the suppressed brain activity in the participants. They also experienced slow reaction times, missed visual cues, and reduced visual scanning of the surrounding environment.

The study concluded that hands-free devices have the same cognitive distracting effects on our brain as a hand-held device does. We may also believe that using a speech-to-text technology may be safer than using a hand-held device or texting while driving, however this method in fact had the highest level of cognitive distraction from all the tasks that were analyzed in the study.

This study unveils concerns we believe do not exist in regards to using hands-free devices while driving. The best way to avoid cognitive distraction and impaired driving is to not talk on a cell phone at all while you are driving. The call, text, or email can wait. Put your phone on silent or turn it off and put it in the glove compartment or back seat so you are not tempted to answer it. Remember: eyes on the road, hands on the wheel, mind on the task.

Dear friends and clients,

In furtherance of our firms culture of commitment to always act with compassion, concern and commitment to our clients, community and colleagues, we have been taking precautions to ensure that we are still fulfilling our ethical and moral obligations while prioritizing health, wellness and safety of all we can. 

As you know, the COVID-19 pandemic has introduced changes to many lives and businesses in our communities, and around the world. We, much like our neighbors and friends, have been taking precautions to ensure that we are still fulfilling our ethical and moral obligation to our clients, while also prioritizing the health, wellness and safety of our employees.

Until further notice, our offices will be closed to the public to encourage social distancing and to help prevent the spread of COVID-19. Our team is still hard at work, many from home, and you may still call, email, live chat or video conference us if you or a loved one is seeking legal assistance. As the first law firm to offer our clients secure online access to their case file more than a decade ago, we have always been believers in using technology to make life easier and information more accessible. In these present times it has been a smooth transition for us to continue to offer our clients the same seamless and thorough service that you deserve and are accustomed to.

This pandemic is unlike anything any of us have faced in our lifetimes, and while we can continue to emotionally support one another through it all, staying home and keeping your distance is vital to the health and wellness of our communities. It does not feel good to break routines, cancel events and retreat from our normal, day-to-day socializing, but let us remember that, in times of strife, prior generations were asked to go to war and we are simply being asked to stay home. Your isolation equals more lives saved, and more time for medical providers to prepare for the treatment of patients battling COVID-19.

When the dust settles, we will join together with a greater appreciation for our lives, local businesses, loved ones and health. Until then, we will continue to offer guidance from a safe distance.

Very truly yours,

Andrew G. Finkelstein and the staff of Jacoby & Meyers, LLP
