The Continental Tyres survey was carried out on several key roads around Dublin: on the N4 near Lucan; the N11 near Bray; and the N7 near City West.
At the N7 site, Continental Tyres enlisted the help of Tele-Traffic -- the leading supplier of laser speedgun technology -- who provided a speedgun with special software that can read the distance between vehicles in both metres and seconds, as well as the speed of each vehicle.
In one 30-minute period, a total of 10 trucks were observed tailgating -- four were driving too close to another truck and the other six were driving dangerously close to cars. The most extreme case involved an articulated truck travelling behind a VW Golf at 89km\h and 88km/h respectively -- the truck was only 0.88 of a second or 18.9m distance behind the Golf. BB
