Real time closures

No change in size, 4 years ago
Major traffic events
If a road closure is part of a larger event, it can be submitted to Waze as a Major Traffic eventEvent, or MTE. MTEs are generally determined by the scale of the event and how many people will be impacted. The closures should be submitted using the MTE sheets provided. This way Waze is able to track the closures and help spread the word. Only if Waze decides not to support the event, or if you don't have at least one weeks advance notice should you submit these closures through other methods.
To notify Waze of a coming event in your area, use the [ MTE Submission Form].
