Before editing the maps in Maryland, be sure to fully review and understand the editing manual.
The Waze user community follows the Waze etiquette guidelines discussed in the Wiki. Be sure to familiarize yourself with these guiding principals while editing the maps and this Wiki, as well as when communicating with other Waze users.
Please review the USA Functional Classification page for details on this topic. In rare cases, a particular road may require a different type than prescribed in the national guidance. Before changing the type of any road past the bounds of the rules, please post the situation to the Maryland Forum to receive feedback. Maryland resources can be found in the following links:
- SHA Highway Location Reference
- nzahn1's Mapping Resources (2012, Google Earth)
- Carroll County

Cities and towns
One of the most common errors when editing the maps is when an editor creates a road and does not confirm the road by setting the city and road name (or stating it has none).
There are 157 incorporated places in Maryland. When assigning the city name to a road segment or landmark, use the name of the incorporated place or CDP (census-designated place). If it is outside the boundaries of either of those, set the city name as None. Do not use the names associated with ZIP codes or the name of a neighborhood, community, or subdivision not included on the census map. If the road type is Freeway, set the city as None (except in Baltimore City), regardless of the location, as this helps with routing. Be sure to also set the city name of any alternate names correctly. Please discuss any deviations from this guidance in the Maryland Forum.
- Maryland 2010 CDP Maps (PDF by County, with street overlays)
- Maryland 2014 CDP / Incorporated Cities boundaries (KML)
- Overlay the above boundary file(s) with the WME Geometries Plugin. After loading the file(s) in WME, turn on the Roads layer (to reference existing CDP/ City names) and the cities layer (to view which WME city boundary may need to be modified).
In Maryland we have a set minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.
A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US road type standards.
Note that these are minimums and, for protection, certain segments may be at higher lock levels. If you find a road locked to a higher level than its minimum, please leave it locked no lower than that level when you have finished editing.
See Maryland/Major roads for guidance in Maryland that may not be universal to all other states and territories.
Maryland follows the standard USA guidelines for all of the following special road types.
- Divided highways and roadways
- Carpool, HOV, Transit lanes
- Roundabouts and traffic circles
- Toll roads
- Partial and scheduled restrictions
- Private installations and military bases
Review the Wiki guidelines for non-drivable roads to ensure compliance with the general guidelines.
Guidelines that vary by state or territory
The following special roads are managed slightly uniquely in some states and territories. This state uses the following standard guidelines found in the Wiki.
Construction projects or emergencies that cause roads to be closed should be reported on this Closure Form. Events that cause road closures should be reported on this Event Form. Current closures and events in Maryland that have been reported to Waze are shown in the MD Closure Sheet.
Not every camera-looking device at an intersection is a speed or red light camera. Generally speaking:
Be sure to know your cameras before accepting new camera reports.
Currently only the Waze client app can add cameras to the map. When adding a camera from the app, be sure to review the camera placement recommendations.
Laws regarding speed and red light cameras vary between the states and territories, so be sure to understand the details of camera legality in Maryland.
Based on information researched at the time this page was created, the limited legality of speed cameras in Maryland is described below, and red light cameras are legal statewide in Maryland.
No other camera types should be mapped in Waze.
Speed cameras are authorized for use in the following areas: school zones throughout the state, work zones on freeways and major highways, and on streets in Montgomery County. Speed cameras can be mounted to a pole, concealed in a metal cabinet on the ground, or mounted on a trailer or vehicle parked on the shoulder, such as these used in work zones. Most speed cameras in Maryland will not issue a ticket unless the vehicle is exceeding the speed limit by at least 12 mph; however, when setting the speed of a camera in the editor, use the speed limit of the road.
Many speed cameras are portable and moved on a regular basis, in some cases weekly. This is usually indicated on the website and may include a rotation schedule. These reported camera locations should not be on the map. However, if the speed camera is not portable or is not moved on a regular basis, then it should be on the map. Check the County-based links below.
Red light cameras
Red light cameras are authorized for use throughout the state. Please note that each red light camera fixture only records violations in one direction, so be sure to check which direction(s) are enforced, and include a camera in the editor for each applicable direction.
Some red light cameras also include radar, and enforce speed limits. This is especially true in Baltimore City.
The Wiki page for Waze Cameras states that, Speed limits "can also be set for a Red Light Camera if it monitors for Speed Limit Violations as well. Leave set to blank if speed is not monitored." However, this function has not been confirmed in the client.
Other camera types
These are cameras or signs that either provide driver feedback or are used for traffic control. These devices cannot issue tickets and should not be mapped. However TRAFFIC Cameras can be used to monitor emergency closures (for accidents, etc.) See below.

These lists are posted for your reference, but should not be used to justify the approval of cameras in Waze Map Editor without first verifying the location and type of camera by other means, and that it is not part of a school zone speed camera program in a jurisdiction where the cameras are relocated on a regular basis. The lists may not be up to date, and may include all locations where cameras are permitted, but does not mean that a camera is present at that location at all times.
To do list
Many states and territories keep an active list of pending or closed actions that need to be done in the state by the editors. All editors are welcome to contribute to the list of activities.
|Visit the Maryland/To do page for ways to contribute to the map.|
The ONLY speed limits added to the map must match federal, state, and municipal laws or regulations that designate maximum speeds for passenger vehicles.
Speed limits that are designated on private property may be added to road segments on the Waze map at the discretion of regional or state managers.
|Speed Limits are added to parking lot and private road types by changing type to street, adding limits, then reverting to the original road type.|
Variable Speed Limits
The WME and Waze app do not support Variable Speed Limits (VSLs) that are changed based on traffic and road conditions. These VSLs can be changed at any time by government officials. If there is a 'standard' speed limit at which the signs on a stretch of road are usually set, this 'standard' speed COULD BE added to the associated road segments in the WME. However, the setting of any speed limit on a road with VSLs must be done in consultation with the appropriate State Manager.
Unsupported Speed Limits
The following speed limits are unsupported by the WME and the Waze app, and MUST NOT be added to road segments in the WME. Road segments with posted 'advisory' speeds or special speed limits should continue the Speed Limit for passenger vehicles as posted on the black and white signs pictured above.
Advisory Speed Limits
In addition, yellow 'advisory' speed signs (as shown below) are usually not enforceable; therefore, 'advisory' speeds, like the ones shown below, should NOT be added to the waze map.
Special Speed Limits
As of February 2016[update], the WME and Waze App only support maximum speed limits for passenger vehicles, without variation for time of day, or day of the week. Specialty, also known as 'bannered', speed limits, like the ones shown below, should NOT be added to the Waze map.
|School zone speed limits that are in effect 24 hrs per day, and 365 days a year, should be added to the map.|
The table below identifies the editors also designated as Area Managers or higher who are editing in Maryland. If you have any questions, please consider contacting them directly as needed. If you are an Area Manager that covers Maryland, or a USA Country Manager that does a lot of work in Maryland, please add yourself to this list (alphabetical by username) in the correct rank section.
The editor who also serves as the Regional Coordinator for Maryland is automatically listed at the top of the table. That editor may not be highly active in this state and therefore may not be listed separately in the table.
