Trip start and end times may vary due to construction, traffic, or other events outside of your driver's control.
We do encourage our drivers to be aware of traffic conditions such as road constructions, major accidents or outdoor events which may delay a trip and to inform you if running late. The best way to help improve safety and quality is to rate your driver immediately after a trip, or from History.
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.
Currently, your rating of the driver is fixed after your submission and cannot be changed.
