How to handle these connectors depends on the exact situation.
== Should the connector be mapped? ==
There are only a few situations in which connectors are called for in an intersection:
*when When the turn lane physically separates from the main road well in advance of the intersection;*when When the turn lane is far enough from the point of intersection on the map (due to the size of the intersection or the angle at which the roads meet) that the driver might overshoot while waiting for a delayed "turn" audible, or that the Waze client might become confused and disrupt navigation*when When the area is "busy" enough that the driver may not get any advance warning that a turn is coming up--in which case a connector lets you notify the driver a little earlier*As an When there are user complaints ([[Area ManagerUpdate_Requests_in_Waze_Map_Editor|Update Requests]], when you get a user complaint ) that the audible was too late, or that the map should have shown a connector
When in doubt, leave it out. Each connector complicates the map and adds to your workload when the time comes to check connectivity, direction, name, etc.
== {{anchor|How to label the connector type}} Road type ==
Although sometimes referred to as ramps, to Waze these are '''not''' ramps. Ramps in Waze should only be used for situations where two roadways have a grade separated intersection or if the situation matches one of the [[#Exceptions|Exceptions]] listed below.
The connector segment's type should be set based on the '''lowest''' of the types of roads it connects.
Also note how the top-left quadrant of the intersection does not have a connector mapped because it does not meet the requirement of being significantly separated from the main intersection.
== {{anchor|How to name the connector }} Road name ==
In most cases, leaving checking None for the segment unnamed Street name will be sufficient. Navigation instructions will simply use the name of the next segment to which the connector segment connects.
If there are specific signs at the intersection which are confusing or contrary to the destination road segment name, then a name can be applied to the connector.
== {{anchor|Geometry of the connector }} Geometry ==
The [[Junction Style Guide]] provides significant information on how to best set the geometry of the connector to get the best routing and text-to-speech result. Be sure to review that article when updating or creating these connectors.
== {{anchor|Turn restrictions necessary for proper connector routing }} Turn restrictions ==
Connectors, if simply added to the map and all turns allowed, would cause significant routing challenges, especially between two 2-way roads. Split roadways have their own challenges, but turn restrictions, due to the 1-way nature of the main segments, are simpler.
If you enable the "show all restricted connectivity arrows" function in the editor at this intersection, you can see there are many restricted turns. This is sometimes a target for someone looking to remove all restricted turns by abusing the use of the 'w' or '''Allow All Connections ''' turns function:

=== Signed, numbered exit ===

'''Example:''' Garden State Parkway Exit 10 in Cape May Court House, New Jersey, USA.
 
The Garden State Parkway is mostly a freeway class toll-road that runs north/south through New Jersey. As the Parkway approaches its southern terminus, the number of lanes is reduced, and at-grade intersections with signed, numbered exits are interspersed with controlled access sections using grade-separated ramps.
=== Connector is a signed, numbered exit ==='''Example:''' Garden State Parkway In order to produce an [[Junction_Style_Guide#Controlling_Turn_Instructions|instruction to Exit 10 in Cape May Court HouseRight]] for the at-grade intersections, New Jerseyrather than Keep Right or Turn Right, USA. we must use a junction angle of less than 45 degrees and The Garden State Parkway is mostly a freeway class toll-connector segment of a road that runs north/south through New Jerseytype other than Freeway or Highway. As Ramp type is ideal for this application because it does not display road names in the Parkway approaches its southern terminus, the number of lanes reduce and app. Segments for numbered exits become a mix of grade separated ramps are named to produce specific visual and TTS instructions, rather than by standard rules for at-grade intersectionsconnectors, and it would be inappropriate to display such names on the map.{{clear}}
