The best way to help improve safety and quality is to rate your driver immediately after a trip, or from History within 72 hours after a trip has ended.
Tap on , History, and choose the driver and trip you want to rate.
The star rating system helps Grab keep a high standard of service that we can all be proud of. It also helps us keep track of passenger satisfaction and maintain high partner quality.
