The only threshold that will automatically get you a reckless driving violation in CA is over 100 mph

Texas has no defined speed threshold

Alabama, where I lived previously on the east coast, has no defined threshold

The guideline for officers in CO is to consider a reckless driving ticket at 26 over the limit and above

I could keep searching individual states but I guess my point is there are many states where 20 over is pretty much a common thing among drivers and not typically punishable with a reckless driving charge. I haven’t spent much time in the northeast, perhaps things are different there.
