On March 11, 2022, Uber announced that it will be rolling out a "temporary fuel surcharge." According to Uber: "Beginning Wednesday, March 16, consumers will pay a surcharge of either $0.45 or $0.55 on each Uber trip and either $0.35 or $0.45 on each Uber Eats order, depending on their location—with 100% of that money going directly to workers’ pockets.
"The surcharges are based off the average trip distance and the increase in gas prices in each state. This is temporary for at least the next 60 days, when we’ll reassess."
