It's getting a bit more expensive to drive a taxi in Palm Beach County. The county commission passed a new law on Monday that requires drivers of taxies, limos and other vehicles for hire to get a national criminal background check and get fingerprinted. That's not free. More than 3,000 drivers would be affected and they'd have to pay another 26-bucks every two years for the background check. The total fee every two years would then be about a hundred fifty bucks.
