Using a cellphone and engaging in other distracting behaviors while driving has been proven to increase the risk of a car accident in various studies throughout recent years.
Which behaviors are more dangerous, however, can depend on the age and experience of the driver. Distracted driving behaviors that involve cellphones include but are not limited to driving and texting, talking while holding a handset and browsing social media or other websites.
A study appearing in the New England Journal of Medicine looked at the different types of distracted driving behaviors, taking into consideration the driver's age and years of experience driving. That study found that some behaviors are riskier than others.
Talking on a handset was not linked to an increased crash risk in experienced motorists, but dialing a number on the phone while driving increased the risk of a car accident for drivers of all experience levels. Texting and driving, reaching for the phone or another object or engaging in any behaviors that require the driver to take their eyes off the road all increased the risk of a crash for both novice and experienced drivers.
