________ is a common clue to law enforcement that a driver is impaired.WeavingHonking the hornShowing the right-of-wayDriving in a straight line

The correct answer is Weaving.

Weaving is a behavior often exhibited by impaired drivers as they may struggle to maintain a consistent lane position. It can be an indicator of reduced motor skills or impaired judgment, which law enforcement looks for when assessing if a driver is under the influence of alcohol or drugs. In contrast, the other options provided—honking the horn, showing the right-of-way, and driving in a straight line—do not typically suggest impairment and may even indicate responsible driving behavior. Thus, weaving is a common and significant sign used by law enforcement to identify potentially dangerous driving conditions.
