Someone posted this over on TA.
"Route Taxis are not required to have insurance to transport tourists where as he was required to have both resident and non-resident (tourist) transport insurance.
He pointed to the stickers on his windshield. The red was for resident insurance and the blue was for non-resident (tourist) insurance. He went on to say that non-resident transport insurance was really expensive which is why nearly no route taxis have them."
Anyone here know anything about this sticker colour thing?
