Tip: Editors are strongly encouraged to download & install the Waze Validator Plugin. This tool will identify map errors and offers guidance on how to fix them. Use this to identify issues in areas you are working on but make sure not to be distracted by errors that do not pertain to you.
Before editing the maps in Illinois, 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.

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).
Some states and territories manage a separate page on cities and towns to identify the specific city names that should be entered, and no others. For states that do not have a separate page to track the names, see this Wikipedia link and find the state or territory in question.
See Illinois/Major roads for guidance in Illinois that may not be universal to all other states and territories.
The provisions for turning in Illinois are defined in Rules of the Road, in Illinois Compiled Statutes 625 ILCS 5/11. In this wiki section we cover two specific situations: Left turns across medians and U-Turns.
Left Turns across Medians
Left turns across paved non-curbed medians are allowed in Illinois, defined in 625 ILCS 5/11-708 (e).
The Illinois Department of Transportation (IDOT) defines several types of medians in Bureau of Design and Environment Manual Ch. 34, Cross Section Elements:
- Flush - A median which is adjacent to traffic lanes and on the same plane as the lanes. These are painted on the pavement surface.
- Depressed - The median between opposing traffic lines is slightly below the elevation of the traffic lanes. It is also designed for drainage and storage of plowed snow.
- Raised-Curb - The curb on these medians is greater than two inches in height.
- Traversable - This type of median has a curb two inches in height.
A Two-Way Left Turn Lane (TWLTL) is typically a flush median. IDOT allows a traversable median to be used as a TWLTL in place of a flush median.
In Illinois, U-Turns can be performed unless specifically prohibited by law. Illinois statute defining the limitations on U-Turns is 625 ILCS 5/11-802 and can be reviewed in the Illinois Secretary of State Rules of Road booklet.
U-Turns can be enabled when editing by enabling the U-Turn flag or at box (#) and partial-box (H) intersections when the median segment is more than 15m in length (See Avoiding U-turns in box and partial box intersections).
When considering enabling a U-Turn, do so only if there is a strong potential to provide improved routing. Some examples of U-Turn implementations are:
- Where driveways or parking lots are connected to a median-divided roadway and doing so would eliminate complex routing to reach the proper side of the road.
- At both connected end-points of a single segment parking lot or gas station to provide an optimal exit route.
Before enabling a U-Turn on public streets, these conditions should be met:
- No traffic control devices posted prohibiting the movement.
- The movement may not be performed on a curve.
- The movement may not be performed on a hill or incline.
- A driver must be able to see in all directions on all roadways a at least 500 feet (153 meters).
- The turn must be able to be completed as a single continuous movement. While not a legal requirement, is best practice for safer navigation.
- At least 15 meters (49 feet) exist from the left edge of the legal departure lane to the right edge of the destination lane, including any median to the left of the departure lane, to allow single continuous movement.
Illinois 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.
Alleys are driveable roads that often provide access to the rear of a business or residence. They can be an important part of the map for routing purposes especially for places with rear access only and for drivers starting a route from an alley.
Guidelines for Mapping Alleys in Illinois:
Generally speaking, only residential alleys should be mapped, and only if they are the locally accepted destination for parking at or near a residence. Alleys should only function as a starting point or final destination, not as a thoroughfare.
In the city of Chicago and the suburbs, do not delete already mapped alleys. Outside the Chicagoland area, alleys may be deleted if they are not necessary for proper routing.
If an alley is to be mapped or updated, be sure to nudge the house numbers.
Road type should be set toand should be named "Alley".
See Illinois/Places for guidance in Illinois that may not be universal to all other states and territories.
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.
When adding a camera, 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 Illinois.
Based on information researched at the time this page was created, the limited legality of speed cameras in Illinois is described below, and red light cameras are legal statewide in Illinois.
No other camera types should be mapped in Waze.
- Mobile speed cameras may be in use in construction zones statewide; these cameras should not be mapped.
- Municipalities with a population of 1,000,000 or more may use speed cameras in safety zones (one-eighth mile from school or park). The City of Chicago is currently the only Illinois community to qualify for speed camera placement.
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.

The table below identifies the editors also designated as Area Managers or higher who are editing in Illinois. If you have any questions, please consider contacting them directly as needed. If you are an Area Manager that covers Illinois, or a USA Country Manager that does a lot of work in Illinois, please add yourself to this list (alphabetical by username) in the correct rank section.
The editor who also serves as the Regional Coordinator for Illinois 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.
