Road Markings part 2 - Double white lines!

Double white lines rules:
These are used to prevent overtaking where visibility is restricted,and to separate opposing traffic flows on steep hills with climbinglanes.
Double continuous lines are also sometimes used on othersingle carriageway roads that have two lanes in at least onedirection.
Viewed in the direction of travel, if the line closest to youis continuous, you must not cross or straddle it (except to turninto or out of a side road or property, avoid a stationary vehicleblocking the lane, or overtake a pedal cycle, horse or road worksvehicle moving at not more than 10 mph).
Where the line closestto you is broken, you may cross the lines to overtake if it is safe todo so.
Stopping is prohibited on any length of road that hasdouble white lines, even if the line on that side of the road isbroken.
The exceptions are stopping to pick up or set downpassengers, or to load or unload. In these circumstances, you should park off the main carriageway wherever possible.
