On the left two roads join; on the right is an exit from an adjacent territory, which is not considered an intersection.
The left picture shows a dirt road joining a hard-surfaced road, which counts as an intersection. The right picture shows an exit from a courtyard onto the road through an arch. Under the law, exits from adjacent territories (for example, from courtyards, parking lots or gas stations) are not considered intersections (article 2). Therefore, an intersection is shown only in the left picture.
Option 2. The right picture shows an exit from an adjacent territory, which by law is not considered an intersection.
Option 3. The right picture shows an exit from a courtyard, not an intersection, so an intersection is shown not in both pictures but only in the left one.
