The conditions that must be met to achieve a working LG at these intersections are
- Both left and right turns are possible at the intersection;
- The two parts of the shared carriageway (entrance and intermediate segment) are more or less in line with each other (maximum offset of 22°, see also the paragraph on corners);
- The two intersecting roads are more or less perpendicular to each other (maximum offset of 22°);
- The intermediate segment in question is 50 m or shorter;
- The number of lanes entering the intersection is equal to the total number of lanes leaving the intersection (total number of lanes leaving the intersection = number of lanes on the intermediate segment + number of right turn only lanes on the entrance segment - in other words, there no new lanes are added or removed in the intermediate segment).
