Tortosaguy is just mad, because in the 20 extra minutes it takes him to get home, we are already in the pool.

geewhiz is correct.  There is nothing in A.R.S. title 28, that allows a person to travel above the posted speed limit; however, legislation was passed recognizing [the majority of] traffic often travels above the posted speed limit (28-721.D [sorry, I didn't have the date handy]) and there was a need to keep traffic flowing smoothly.  Think about this: four people are traveling at 70 MPH, they approach a person (in the left [#1] lane) who is traveling 65 MPH.  The first 70 MPH car to reach the 65 MPH car has to slow, but ends up slowing to a speed less than 65 MPH...let's say 60 MPH (just to make the math easy.)  The second 70 MPH car now has to slow, but it slows to 55 MPH.  The thrid 70 MPH car the slows to 50 MPH, etc.,etc.,etc.  The whip always cracks at the end.  As I previously posted, it is not often enforced, because officers would have to tell people to keep from breaking one law, they have to break another...or drive on the right side of the roadway.  It is considered dangerous to pass on the right (especially for motorcycles) because people are more apt to go right to exit, turn, car trouble, etc.  Having said that, it is very important for people to understand: the faster you go, to more violent the collision will be.  I personally think it is proper etiquette to drive in the right lane unless passing.  I equate it with a person so lazy, they put their shopping cart wherever they please, taking up parking spots, allowing carts to roll into vehicles, etc., rather than putting it into the "cart parking."  If another person wants to drive faster than you, why not let them?  Let the police stop them if they see fit; it is not a civilian's job to enforce traffic laws.  We live in an "Entitlement Society," too many people are self-absorbed and don't look at/don't care about the "big picture."  Always looking out for themselves, not caring about the effects they have on other people.  Remember:  Baby-boomers could be told what to do and got it done.  Gen-X'ers once shown how to do it, are "get it done" people; Generation Y'ers ask "why" (really, no pun intended) and prefer to be called the "Millenials."  - S

Actually, the ARS does define what "slower traffic" means, by proxy. The MUTCD (per the ARS, the adopted manual for what traffic control devices mean) defines the sign to mean:

Section 2B.31 SLOWER TRAFFIC KEEP RIGHT Sign (R4-3)

Guidance:
If used, the SLOWER TRAFFIC KEEP RIGHT sign should be installed just beyond the beginning of a multi-lane pavement, and at selected locations where there is a tendency on the part of some road users to drive in the left lane (or lanes) below the normal speed of traffic. This sign should not be used on the approach to an interchange or through an interchange area.



So you can see, the sign is a complement and visible reminder of our already existing law that says to keep in the right lane if you are going slower than traffic. It doesn't matter that the person is artificially holding down traffic speeds, they are still going slower than normal traffic speed.


You can easily gauge what the normal speed of traffic is and note that it is not capped at the speed limit. Police need to start enforcing this law and these signs and we will have smoother commutes.

And before we get into what the "normal speed of traffic" is, anyone who doesn't know doesn't have any business driving, as it is required to determine traffic speed any time any sort of merging is done.

AZ.....ill make it to the junction of the 347 and I-10 before you do using a future cut through if they ever make one...and yes ive seen plenty of maps =)

Honestly geewiz, stay away from the little glass pipes.  Jason, thank you for pointing out the signs.  I finally forced myself to look for the signs and observed them posted beyond most the intersections.  Do you have any idea how long they have been posted?  I kept threatening (to myself) to call ADOT and ask why they wouldn't put up such signs.  Glad they weren't snakes.  I guess I shouldn't run for U.S emporer this year
