Switching to ground....

It's important to remember that authorization from ATC does not relieve the
pilot of responsibility for safety. There is nothing wrong with stopping at
the hold short line and taking a look to make sure you are not about to
taxi into someone's takeoff or landing roll...

But once you have verified it is safe, you do not require additional
permission from Tower/Ground to continue...

I am not clear why 'cross any intersecting runways' is a particuarly
safe thing to do. This may make sense at a familiar airport where you
know the taxiways and intersecting runway. At unfamiliar airports, I
get extremely nervous when crossing an intersecting hold short line.
There could be more than one way to get to the assigned runway, and you
may be following a different route than the one the controller had in
mind and inadvertantly cross an active runway. At unfamiliar airports I
stop and verify clearance to cross. I've had controllers get annoyed at
me for that, but better be safe than sorry. Given the increased rate of
runway incursions, this rule never made any sense to me.

Then I've committed an awful lot of runway incursions without
ever being told about it.


Well, you have if you crossed the assigned runway. If you merely
crossed other active runways that were not assigned to you then you're
okay.


§ 91.129 Operations in Class D airspace.

(i) Takeoff, landing, taxi clearance. No person may, at any airport
with an operating control tower, operate an aircraft on a runway or
taxiway, or take off or land an aircraft, unless an appropriate
clearance is received from ATC. A clearance to "taxi to" the takeoff
runway assigned to the aircraft is not a clearance to cross that
assigned takeoff runway, or to taxi on that runway at any point, but
is a clearance to cross other runways that intersect the taxi route to
that assigned takeoff runway. A clearance to "taxi to" any point other
than an assigned takeoff runway is clearance to cross all runways that
intersect the taxi route to that point.
