A study by the Transport Research Lab has found that motorists who are driving then use their mobiles to send a text message are at a very high risk of having an accident. It was found that their reaction time decreased by 35% which is much worse than those who drink and drive (12%) or those on drugs (21%).These drivers were also far more likely to drift out of their lanes while trying to pay attention to two things at once. Their steering control was a striking 91% poorer than drivers fully paying attention to the roads.It is illegal to use a mobile phone while driving and the RAC foundation said that nearly half of people aged between 18 and 24 said they admitted to texting while behind the wheel, but only 144,000 people were prosecuted for using their mobiles while driving.A text message while driving on average, took 63 seconds to compose while it only took 22 seconds to compose a text when sitting at your desk.I personally am still seeing many drivers on the road using their mobile phones to talk and think it is so unfair on those of us who pay due care and attention while driving. Some motorists these days seem to forget about road courtesy altogether. So many stop on yellow boxes where you can get fined, stop over clearly marked 'Keep Clear' signs and block traffic flow so they don't lose their space, not realising that some are actually for fire trucks and ambulances in an emergency. It's a big shame that everyone is always in such a rush to get somewhere that they may feel like they have to use the mobile phones in the car as there are not enough hours in the day. Congestion on the roads causes people to lose time at work and personal time so they may feel like they have no choice.It's an on going debate, however it is vital that people concentrate 100% on the roads as within a split second things can change.
