# Priority Intersection
A priority intersection is an intersection that is not controlled by traffic lights. At a priority intersection, vehicles will continue through if there are no other vehicles inside the intersection. Otherwise, they will stop and wait for other vehicles to pass.
For a priority intersection to work it needs to have at least 3 roads (a 2-road intersection is a straight road) and there is no maximum number of roads for an intersection.
Usually, an intersection looks like this:
As you can see from those red waypoints, the roads are not connected, so you should connect the roads as you see fit. Check the [connect-roads](https://gley.gitbook.io/mobile-traffic-system/setup-guide/connect-roads "mention")section.
I will connect the roads like this but you can do it in any way you want.
After all roads are connected, create a priority intersection.
Go to **Settings Window -> Intersection Setup**
If **Show All Intersections** is checked you will see the intersections from the entire scene. If unchecked, only the intersections visible in the scene view will be displayed. Using the **View**, **Edit,** and **Delete** buttons you can perform the respective operations on each intersection from that list.
Press **Create Priority Intersection** to create a new intersection. This will open the Priority Intersection Setup Window.
**Hide Waypoints** - will hide the scene waypoints offering you the possibility to select different objects inside the scene.
For each road that enters the intersection, you'll have to press **Add Road** and then **Assign Road Waypoints.**
Select the waypoints where you want cars to stop. Selected waypoints will be marked with red circles.
When the selection is finished, press the **Done** button.
Do this for all roads in your intersection.
You can add more waypoints to any road by using the **Assign Road Waypoints** button.
You can delete a waypoint or the entire road by using the **Delete** button.
Using the **View** buttons, you can focus the scene view on the selected waypoint.
**Adding exit waypoints is mandatory.**
Press **Add Exit Waypoints** and select all the waypoints through which cars can exit the intersection. Exit waypoints are marked with green circles.

**Attention**! If a vehicle can exit from an intersection without passing an exit waypoint (you miss assigning an exit) the intersection will stop working thinking a vehicle is still inside the intersection and will not allow others to enter.
