The traffic engineer may erect signs lettered “do not enter” in prominent letters at the entrance to any road, street, lane, driveway, ramp, taxiway, runway, or area at Love Field or Dallas Executive Airport. A person commits an offense if he operates or drives a vehicle past a “do not enter” sign; except, this section does not apply to authorized vehicles, designated by the director of aviation. Pedestrians shall obey the “do not enter” signs the same as operators of vehicles, and pedestrians shall not enter any area of Love Field or Dallas Executive Airport except by regularly provided entrances.
