From the jackets to the course, the color of the week is definitely green. And many folks in town are trying to find unique ways to make some green. But, the city plans to put the brakes on something it says is a safety hazard.

"When they get in my van at the end of the day they're very tired," said Janice Easterling. "So happy to be there.

She is one of a handful of folks running "free" shuttles to and from the course. But , she concedes -- she's driving for dough.

"I don't charge at all. They're welcome to give me tips, whatever denomination they please," she said. "It's pretty good."

Now the city is saying: not so fast.

"Take the signs off the vehicle that say tips," said Rob Sherman, Director of Richmond County License & Inspections. "You can't pretend to be a taxi service if you're not licensed."

Even selling water bottles on the street is illegal, but Masters week the city is looking the other way.

But officials say the hazards on the road are just too great to ignore.

"They're not licensed, the cars haven't been inspected, we don't know if they have insurance to cover the riders," Sherman said.

Officials told NBC Augusta they' ll start cracking down on the shuttles.Violators could owe up to $1000 and even face jail time.

Easterling said she's made every effort to drive the fair way -- checking with her insurance and even the DMV, plus, she said it's a service Augusta needs this week.

"They really don't have proper transportation, they really don't," she said.

Easterling told NBC Augusta she was not aware she needed a business license and will begin that process Friday.

NBC Augusta spoke with several insurance companies. Most said they would not cover these shuttles or their passengers in an accident.
