When flood waters rise, safety officials dive.

Harvey served as a reminder that flooding is a serious threat that GPSTC director Chris Wigginton says comes with a warning.

"If there's water in the roadway, standing or moving, don't drive through it," he says.

Even a few inches can pose danger.

"12 inches of water swift, can move an automobile if it's swiftly moving," Wigginton says.

Swiftly moving, or just an ominous unknown.

"The road could be completely washed out, and you drive through and you're in a situation where you're submerged in water, " Wigginton warns.

However, if you do happen to get stuck in one of these situations, Henry County Fire Battallion Chief Jonathan Burnette says there are a couple of things you need to do.

"If you do happen to find yourself stuck in one of these situations, there are a couple of things you need to know, one of them being unbuckle your seatbelt," Burnette says.

Don't have the old roll-down windows? Burnette says there's a tool for that.

"We recommend some sort of little emergency hammer in your car that has some sort of punch on the end of it, so you can actually bust the window out with so you can have a way to escape and get out of the car."

Either way, Burnette says he and his crew are more than prepared to help, if need be.

"We have several training events happen throughout the year, should a situation occur where we have to perform some type of rescue, we feel very confident in our abilities that we will be able to do that."
