Motorway construction sites – narrow tracks, e.g. A 31

Hi guys, I don’t find the right one in the archive, so I’m opening a new one here. How do you hold it in the highway construction sites, where a concrete or metal wall is built on the right side, while the right track is very narrow, and the left track is 2.1 meters wide. With the truck you fit on the right side so easily, if I drive left with the outer edge about on the middle strip, I felt to the right about 20 cm space, I guess. Maybe the right track is also 3 m wide, But it seems dangerously narrow to me. I drive on the A 31 several times a year, there are currently two construction sites á 5-6 km. Three times it was felt almost crash, when a SUV and twice a station wagon passed me to the left, I had felt to the right maybe 10-15 cm, the overtaking car to the left and between us too, felt. There was a very nice nozzle, when it sometimes scrapes at the side, or I come to the right, then it cracks and everything is blocked. Car overtakes me and the saddle in front of me, and this probably also got such a shock that he then drove in the middle for the rest of the construction site. Tempo was about 65 at allowed 60. I almost always see several trucks on this construction site, which drive so far in the middle, so that no one can overtake. Now my questions: What minimum distance do you have to hold to the right wall ? 50 cm ? Or drive the not intentionally “centered”, but keep the required distance to the right , and then nobody can overtake it, because it is then left too narrow, so no intention or coercion. How do you hold it, I drive right and hope that nothing happens ? If you are only allowed to drive 60 (and you drive maybe 65), no one should drive faster on the left anyway. So it would be useful to drive in the middle to keep the necessary distance to the right and there is no unnecessary accident. What do you think ? VG, Andre
