I decided to try ridershare with Lyft, and my background was approved. Should I wait for my sticker or decal to drive? Or just print one offline? There isn’t a Lyft office near me, so I can’t pick one up.
If you want to display a decal on your vehicle, then print one. I think that's what Lyft even says in their instructions when you start. Some cities/areas/airports etc. require you to display it, some don't.
For pax, however, the best thing to do is to match license plate/vehicle/driver picture to be absolutely sure they are getting into the correct one. Anybody can buy Lyft/Uber stuff from Ebay, Amazon etc. or print them themselves.
