Double white centre lines, especially where one or both are solid, restrict overtaking. Crossing solid centre lines to overtake is generally prohibited. These markings are used where overtaking is dangerous, such as on bends, near intersections or where visibility is limited. Broken lines may allow overtaking when safe, but solid lines indicate you must stay in your lane. Ignoring these markings can lead to head-on collisions and serious penalties. If you are behind a slow vehicle, wait for a legal overtaking zone with clear visibility and broken lines. Patience is safer than a risky pass.
