by Trish Whelan.Drivers who tailgate other vehicles or use a handheld phone while at the wheel are the most dangerous threats on the road, according to a new survey in Britain from the Institute of Advanced Motorists.
More than half of all drivers regard each of these two activities as 'highly dangerous', according to a survey of almost 700 motorists.
Drivers who overtake on single carriageway A-roads when there is oncoming traffic, and those who cut others up, forcing them to brake, are regarded as the next most dangerous threats.
