Crossing double white lines in the middle of the road is permitted only when the line closest to your vehicle is broken. This rule is in place to ensure safety while allowing for specific driving maneuvers, such as overtaking. The broken line indicates that it is safe for a driver to change lanes or overtake another vehicle, as long as the maneuver can be executed without creating a hazard. If both lines are solid, this indicates that overtaking is not allowed due to potential dangers, such as limited visibility or proximity to junctions. Therefore, the only time it is permissible to cross double white lines is when there is a broken line nearest to you, indicating it is safe to do so. This rule helps prevent dangerous situations while still allowing for necessary overtaking when conditions allow.
