The effect on passenger cars’ meeting margins when overtaking 30 meter trucks on real roads.

The purpose was to study the effect of vehicle length on meeting margins during overtaking maneuvers. A field study video-recorded overtaking maneuvers of a 30 m and a 24 m truck on a two-lane road. The difference in average meeting margins between the trucks was not statistically significant. An ocular assessment of the video material revealed a few critical situations during the overtaking maneuvers of the 30 m truck; all with meeting margins less than 3 s. Although these results should be interpreted with great caution as the number of analyzed overtaking maneuvers was limited, two previous studies describe similar findings. The conflict technique is discussed as a tool in the assessment of critical meeting margins. It is concluded that more field studies and data are needed to estimate the risks when overtaking Longer Combination Vehicles.
