Beginning Thursday, police will be ticketing drivers who use the Ga. 400 shoulder lane outside the approved morning commute hours.

Last month, the Georgia Department of Transportation opened up the shoulder lane of Ga. 400 from Holcomg Bridge Road to Northridge Road  to help ease traffic during the morning commute.

The lane is only allowed to be used from 6:30 a.m. to 9:30 a.m., Monday through Friday. Outside of those times, it is illegal to drive on the flex lane and police said they are done giving warnings.

Sandy Springs police said drivers using the lane outside of approved hours is dangerous. They showed dash cam video of drivers blocking emergency vehicles.

Police said using the lane outside the morning commute is not only a danger to emergency vehicles, but also for disabled drivers.

“They come over the hill and they’re running 65, 70 mph, they’re going to run right in the back of somebody,” Tim Sheffield of the Sandy Springs Police Department said. “I believe it’s just impatience. They see that lane and they know they can use it at certain times, so why not use it outside that window?”

Channel 2’s Sophia Choi also caught drivers using the lane outside of the allowed time frame.

Some drivers told Choi the lane is confusing and should either be open to drivers all the time, or not at all.
