The product | Bring changes on the road into navigation

Waze is a navigation app whose users can report hazards and other live road conditions for people coming after them. Potholes, fallen objects, and vehicles stopped on a shoulder do not last equally long. A report that is accurate today need not remain accurate indefinitely.

This article focuses on ordinary hazard reporting and feedback. Official Waze help says report visibility varies with other users’ reactions. “Not there” shortens display time; it does not mean one click immediately deletes a report. Road hazard help

Save the location and report a hazard; later Not there feedback shortens display time rather than immediately deleting it

The core flow | Report what is there; later passersby update whether it remains

  1. Report only real-time conditions near your current location. Tap the Report icon in Waze; the location is saved when you begin. Only perform the interaction when it is safe to do so.
  2. Choose Hazard. It defaults to a general hazard, or you can choose a more specific type such as construction, a vehicle on the shoulder, a broken traffic light, a pothole, or an object on the road.
  3. Tap Report or wait for automatic submission. Your username accompanies the report. If connectivity drops after you start, Waze saves the report and submits it when the connection returns.
  4. Give current feedback when passing an existing report. Choose Not there if the hazard has gone. This shortens how long the report is shown. Waze does not publish a fixed lifetime or a “delete after this many votes” formula here. Reporting steps and common questions

Design lessons | Treat location, type, and useful lifetime separately

Capture the location before completing the details. Road reports arise in a brief situation. Saving the location when reporting begins avoids confusing the incident’s position with where the vehicle is when the description is completed. Public-facility inspections can similarly record where a problem was found before organizing its details.

Let later passersby update whether it is still there. This is not a permanent rating of the reporter; it adds to a fact that can change. Separating “was the report accurate then?” from “is it still present now?” avoids treating ordinary disappearance as a false report.

Fading out is part of the service. The timing of removal affects trust in navigation clues. Pursuing only more reports lets stale information accumulate; clearing one after any negative response may remove a remaining hazard too soon. Waze publicly describes a shortened display time, which does not reveal its internal weights. The transferable lesson is to design feedback and an exit for transient information as well as an entry.
