Hands-free is not risk free.
The science is crystal clear on this fact and numerous studies have demonstrated that the use of handheld and hands-free devices while driving pose a significant safety risk to motorists, their passengers and others on the road.
Hands-free devices and voice command systems create a cognitive distraction as the driver mentally engages with interactive tasks.
While hands-free options may be marginally safer than handheld devices, eliminating driver use of all types of cell phones and in-vehicle infotainment systems is safest.
Drivers think cell phone use is distracting … for other people
Although 87% of people think talking on a cell phone while driving is a serious safety threat, 49% have talked on a handheld phone while driving. Drivers should talk the talk AND walk the walk, refraining from using their phone when behind the wheel.
It is impossible to multitask and give equal attention to each task
People often think they are effectively accomplishing two tasks at the same time. It is possible to complete a phone conversation while driving and arrive at the destination without incident, but it is a misconception that the tasks can be done simultaneously and as safely as possible. Motorists should make driving the primary focus and perform other cognitively demanding tasks only when safely parked.
