Hi Alex,

Arizona does not have a requirement for a front license plate, just the rear.
As far as being stopped, just like any other state there are speed traps, but
unless you are doing something that calls attention you should not have a
problem.

Most the cars that are here that seem to be going fast have California plates!

Alex,
    Front license plates are not required in Arizona. I-10 once your get to
Blythe the speed limit is 75mph in AZ. Average speed is 85 but some Semi
trucks will blow past you.
    Driving a Champ pickup at 70 MPH makes you feel like a pylon in the
highway!

The same situation exists in most states, even where the limits are lower.
On I-95 between Washington and Richmond it is essentially a matter of
self-defense to drive at least 80.  Otherwise you get run over.  Last
weekend I drove 200 miles on I-81 in Virginia and didn't see a single police
car.  I was holding between 75 and 80 in the Avanti and I didn't pass many
people (and my speedometer is right on).  I was talking to one of my
students (who is a Winchester, VA town policeman) and he told me that the VA
Highway Patrol is way under staffed.  They can't pay competitively and their
personnel practices are from the dark ages.  As a result, they can't stop
the marginal speeders (10 or mph over the limit), only the gross ones (100
mph in a 65 zone) or people driving dangerously (weaving in and out,
racing).

BTW- one of the news programs (60 Minutes or Dateline) in the past week
showed videos taken in cars driven by young guys who made a sport of racing
on I-95 south of DC- speedometers reading from 120 to 140 mph.

Alex,
I don't have a front license plate either, so we can at least keep each
other company in jail if we get busted.

And don't worry about the speed.  With my lack of OD and with my 3.54 rear
end, I'll keep our little convoy slowed down nicely <g>.
