Waze users will soon be able to choose to be notified about whether they are speeding, so map editors are now adding speed limits to road segments.
All speed limits added to the map must match federal, state, and municipal laws or regulations that designate maximum speeds for passenger vehicles. These are white signs with black lettering. Advisory speed limits should not be used. Part-time speed limits should not be used.
Speed Limits Near intersections
If a speed limit sign changes the speed limit, and it is 200 feet after the intersection or closer, start the new speed limit AT the intersection.
Speed Limit Sign Location
Look for speed limit signs at the beginning and end of each speed zone, and every 1/2 mile or closer, though some of these signs might be missing in rural areas. 
Roads Without Speed Limit Signs
If there are no posted signs, follow the PA guidelines:
(1) 35 miles per hour in any urban district.
(1.2) 25 miles per hour in a residence district if the highway:
(i) is not a numbered traffic route; and
(ii) is functionally classified by the department as a local highway.
(2) 55 miles per hour in other locations.
Adding A speed Limit in the Middle of a Segment
When a speed limit changes in the middle of a segment, cut the segment at that point to enter the two speed limits. An example of where this has been done can be found here. If the speed limit changes within 200 feet of an existing junction, make the speed limit change at that junction.
Speed limits we will not add
Construction Speed Limits
Do not use temporary construction zone speed limits unless it is a long term project and this should be done in consultation with State Managers.
Speed Limits that vary
If the speed limit changes depending on road conditions, time of day, or day of week, only the 'standard' speed, if any, can be added in WME.
Advisory Speed Limits
Advisory speed limits are speed limits that are not legally enforceable. Do not add them to the waze map.
Special Speed Limits
Only maximum speeds for private vehicles can be added. Do not add special speeds for other types of vehicles.
