As countries are lifting restrictions all over the world, cab-hailing services such as Uber are beginning to resume their operations. As a part of its new guidelines, the company has made it mandatory for riders and drivers both to wear masks and follow sanitization instructions.

However, if you violate Uber‘s guidelines by not wearing a mask or taking it off during the ride, the driver can report you to Uber — and you’ll have to face the music. You will first get a warning from the company. But with multiple violations, the company can kick you out of the platform.
