After initial backlash to the arrival of uberX to Myrtle Beach in July, city staff issued a stern warning to those who participate in the ride-sharing service.

Police issued four citations to three uberX drivers in late July through “sting operations” and all three drivers requested jury trials. No trial had been set as of mid-December. Officers have not issued any citations since July, police spokesman Lt. Joey Crosby said.

“We’re monitoring their activity and we’re investigating what they’re doing,” Crosby said.

A judge in Charleston found uberX driver Taft Navarro guilty Dec. 5 for violating transportation rules, the first known ruling in the region. He was ordered to pay $437 for operating a ride-for-hire service at Charleston International Airport without the necessary permit.
