When a driver enters an average speed check zone, Waze could display both the legal speed limit and the driver’s current calculated average speed since entering the zone. Additionally, the app could show what the driver’s remaining average speed needs to be in order to stay compliant by the end of the zone.

Example:

“Average speed check zone — Limit: 90 km/h.
Current average: 95 km/h.
To stay compliant, reduce speed to 85 km/h.”
