Operation Thunder is back in Richmond County. The Richmond County Sheriff's Office says November and December of last year were the worst months for traffic fatalities. Because of that, the Governor's Office of Highway Safety and several other agencies will be setting up police checkpoints over the next several weeks. Friday night, Lt. Blanchard tells NBC 26 that 30 people were busted for DUI. There were also 39 child restraint violations and five marijuana cases. Deputies will be back out, Saturday night.
