Passenger rating information is always displayed to the driver before accepting an order. The driver can not refuse to rate. He must evaluate each passenger. This helps Uber to obtain objective information about its passengers.
According to Uber: “After each trip, riders and drivers have the opportunity to rate one another from 1 to 5 stars, based on their trip experience. Ratings are anonymous. Neither riders nor drivers see individual ratings tied to a particular trip or person.”
Yes, the uber driver can see the passenger rating, but in some states the rating and even the passenger's name may be hidden from the driver.
