> Two solid yellow lines prohibit vehicles from crossing them to pass another vehicle. You may not cross these lines unless turning left when it is safe to do so.

For the record I drive. I also happen to know the laws and accept I can be ticketed if I pass a vehicle that is turning on the road by crossing the double yellow.

Just because it’s common practice doesn’t mean it’s legal. The only time you’d have a case is if the road is obstructed by an illegally stopped car or a broken down car.
