Driving abilities of older drivers were much more reduced than that of younger ones. Also, it has been confirmed that regardless of which mode of mobile phone was used while driving (‘‘hands-free” or ‘‘hand-held”), contents and emotional intensity attached to the conversation played a key role with respect to keeping the attention and driving performance at a satisfactory level.Several studies examined the risks of mobile phone use while driving (‘‘hands-free” or ‘‘hand-held”). By summing up the results of such studies it can be concluded that the authors of mentioned studies have confirmed the connection between mobile phones use while driving and the relative risk of car crash occurrence. Namely, relative risk of a car crash is considerably higher for drivers who use a mobile phone while driving than for those who do not. Similarly, the authors of these studies have found that younger drivers are at higher risk of being involved in a crash.
