Broken White Line
A broken white line separates two lanes traveling in the same direction. Once you have signaled, and if it is safe to do so, you may cross this line when changing lanes.


Solid White Line
A solid white line marks the right edge of the roadway or separates lanes of traffic moving in the same direction. You may travel in the same direction on both sides of this line, but you should not cross the line unless you must do so to avoid a hazard.

the above is from the florida drivers manual....passing per se is not allowed with a solid white line nor is the word 'should' a carte blanche.
