Driving on the highways in and around ATL, DAL's biggest hub, by definition is speeding. If you happen to be the unlucky driver who gets pulled over, oh well, it's a cost of doing business.
Bottom line, be 100% honest and accurate in these disclosures. Do not try to hide this stuff. You will either not get the job, or you will get pulled out of newhire class for lying. Just tell the truth.
