Internal road - a non-public road, which may also take the form of a parking lot or a square intended for vehicle traffic. Most often, such roads can be found in housing estates, but they can also be communication areas near shops, especially hypermarkets.
On internal roads, both publicly accessible and those with limited access, we must apply regulations that regulate direct relations between road participants:
The beginning of the internal road is marked by sign D-46, and its end by sign D-47.
When leaving an internal road, you are merging into traffic. In this situation, the driver must be especially careful and give way to all other road users.
Traffic zone is an area including at least one internal road, the entrances and exits to which are marked with appropriate road signs: D-52 and D-53.
