All runway markings (in the US at least!) follow the same rules. Think of the following when you're looking at airport markings:
-As you approach the markings, are the lines across dashed or solid?
-If they're dashed, you can cross with no problem
-If they're solid, you need to stop, or at least make sure you're allowed to pass over them before proceeding.
A note printed on the older ones:
"ATC permission is ALWAYS required to cross from the solid side to the dashed side"
There's a pilot guide the FAA has available (I got mine from my first flight instructor). A picture of both sides:
Here's a good web site that has all of the airport markings and a demonstration of each:http://www.pilotfriend.com/training/flight_training/communication/taxiway_markings.htm
