You probably think that talking or texting on your mobile phone may be the most distracting thing you can do when you are driving – but this may not be the case.
Researchers have found that performing entirely legal tasks when driving may actually serve as more of a distraction than those that are illegal.
The University of Utah investigated the worse distractions when driving and found that using a sat nav while driving was actually the greatest distraction for motorists.
As in-car technology continues to get more and more advanced - and ironically aims to stop people picking up their phones when behind the wheel – it may serve as an even greater danger for motorists.
Joel Cooper, a researcher and associate professor at the University of Utah, said: "We're really moving in the wrong direction with a lot of this technology."
The university asked 120 drivers to perform four simple tasks – calling, texting, tuning a radio and programming a navigation – on 30 different cars to test, and found that using a built-in distraction may pose as the greatest distraction. Twenty-three of the cars' systems were found to demand high levels of attention, while the other seven were described as "moderate".
