The term "righteous indication" means different things to different people.
For some, particularly religious folks, indicating one's righteousness is a sign of their faith. Christians may wear a cross. Jews a yarmulke. Muslim women may wear a hijab. Priests wear a scapular. Nuns wear a wimple. Nationalists, a "Don't Tread on Me" t-shirt, an oversized knife sheath, and a scraggly beard. Cat lovers, clothing covered in cat fur. People like to indicate what they worship with clothing and jewelry.
In traffic, "righteous indication" usually refers to turn signals. If you are righteous, you will use your turn signal in an appropriate manner. If you are righteous (or at least economically responsible) and you are driving through Idaho, you will turn on your signal at least ten seconds before you change lanes or you'll get ticketed. Especially if you have out-of-state plates.
If you are a child of the 80s, "righteous" has a whole 'nother meaning. For us, "righteous" is akin to words like "cool," "nifty," and "Well done, sir!" It is used for gnarly guitar solos and radical rail slides. It is indicated by hook-em horns and a properly drawn-out, "Righteous, doood!"
None of these examples are biblical issues and only one is moral: turn signals. If the driver in front of you does not engage in righteous indication before turning, your
righteous indignation is justified!
