Permanent Hazards (PH) are a Waze feature that allows Waze to display warnings of upcoming Hazards on the map that are always present, unlike temporary hazards such as floods, roadkill, and potholes.
The following PHs can be mapped:
- Speed Bumps
- Toll Booths
The UK Champs have decided that the following PHs are not to be mapped in the UK as they do not suit the UK road network and are too subjective to map:
- Complex intersection (junction)
- Multiple lanes merging
- Sharp curves (bends)
Mapping hazards
To map Permanent Hazards, the Hazard Layer must be enabled. The PH types can be found under the Hazard menu.
After selecting a PH from the menu, moving the cursor around the map will display the segment to which the PH will snap. Click the left mouse button to set the PH’s position. PHs are bi-directional. If the PH is placed onto a one-way road, the PH will only work in the direction the segment is running. If placed onto a two-way road, the PH’s direction can be changed (A->B/B->A).
The current Editor Rank to add or change a PH is L3, but this will also depend on the level of the road segment the PH is being added to or changed on. Any PHs attached to the segment will also be deleted if a segment is deleted.
Permanent hazard types
Level Crossing alerts
Level crossings throughout the UK have now been mapped with LCAs. These are alerts similar to cameras and work in the same manner in the client. LCAs should be added using two one-way pins placed at the stop line. Red light cameras should not be added, even if there is a camera, as one: they will interfere with the LCA, and two: Level Crossing Alerts should be enough of a warning.
Tram crossings that are controlled by regular traffic lights should not be mapped with Level Crossing alerts.

You can discuss more about LCAs and get assistance in the dedicated forum post. |
Speed bumps
Speed bumps can be added to the map by L2 editors and above. Speed Bumps are to be mapped for all speed bumps* (not just the first and last of a group). For added convenience, a keyboard shortcut is available (check your keyboard shortcut settings).
*Do not map Speed Bumps in car parks. Drivers should already be going slow enough not to need an alert.
Toll booths
As there are not many Toll Roads around the UK, there are not many Toll Booths. These are all mapped already, so unless there is a change, there should be no need for additional changes to this PH type. Please contact the UK champs if any changes are required.
Toll Roads that are free-flow, with no Toll Booths (for example, the Dartford Crossing and Mersey bridges) must not be mapped with Toll Booths. Also, Car Park Booths or barriers must not be mapped as Toll Booths.
Alerts on the client
PH alerts will be displayed on the client 500 metres before the hazard has been mapped as a takeover with sound. They will only show and alert when driving on a planned route (i.e. not “free driving”.)
Multiple pins capping: When multiple PH of the same type occur in proximity (less than 500 from each other), the app will show one notification letting the driver know that there are multiple occurrences of such a type ahead.
Familiarity capping: The app has a mechanism to prevent audible alerts if a user uses the same route regularly. The alert’s icons will still appear on the map regardless.
