Drivers can also be stopped when an officer suspects you were attempting to avoid a nearby roadside checkpoint.  “[N]ormal driving that incidentally evades a roadblock does not justify an investigative stop, [but] abnormal or unusual actions taken to avoid a roadblock may give an officer a reasonable suspicion of criminal activity even when the evasive action is not illegal." Jones v. State, 259 Ga.App. 506, 507 (2003), citing Taylor v. State, 249 Ga.App. 733, 735, (2001).
The officer may have noticed you pull over to the side of the road a short distance before the roadblock or make an abrupt turn onto a side road. If your driving behavior was sufficiently suspicious to give the officer an articulable suspicion that you were eluding the roadblock, the stop may be valid. An abrupt turn without signaling or a turn into a closed business prior to a roadside checkpoint may appear as evasive. See Terry v. State, 283 Ga. App. 158 (2007).
