MINNEAPOLIS (AP) -- An Uber driver is in a fight with Twin Cities airport officials over a sign on his car.

Paul Linnee of Bloomington has a sign on his car that reads ``UBER-PAUL.'' He says the sign helps riders at the Minneapolis-St. Paul International Airport identify him.

But the Metropolitan Airports Commission has ordered him to drop the sign or quit serving the airport.

Commission regulations prohibit advertisements on ride-sharing vehicles and the panel considers Linnee's sign an ad.

Commission spokesman Patrick Hogan also says that the sign creates confusion because many ride-share drivers have the same name. He says if customers started looking for names on cars many riders would get into the wrong vehicle, creating a safety risk.

Linnee says the commission's edict is ridiculous.
