Although many people believe that using hands-free technology while driving is safer than holding the phone, recent research conducted by psychologists at the University of Sussex suggests otherwise. According to the study, when drivers use their phones while driving, they are forced to engage in visual imagery, which can activate the same part of the brain that is typically used to watch the road. As a result, even simple phone conversations can cause a driver to concentrate on an area that is four times smaller than usual, increasing the risk of accidents on the road. The study also found that drivers who used hands-free technology took longer to react to potential hazards, such as pedestrians or oncoming vehicles. On the other hand, having a passenger in the car is less distracting since the conversation can stop when necessary. For instance, passengers are more likely to pause the conversation when the driver needs to focus on the road.
For example, a driver who is using hands-free technology might be more focused on the conversation and less attentive to the road, leading to increased chances of an accident.
