In New South Wales, road markings are essential for regulating traffic flow and ensuring road safety. Understanding what each type of line means—and whether you can cross it—is vital for all drivers.
A single broken (dashed) line is the most common and indicates that drivers may cross to overtake or change lanes, as long as it is safe. A double broken line has the same meaning, allowing crossing when conditions permit.
A single continuous (solid) line is more restrictive. Drivers must not cross it unless entering or leaving a road, driveway, or property, or to avoid an obstruction. Double continuous lines are the strictest—crossing them is illegal in almost all circumstances, including overtaking. The only exceptions are to access a property or make a U-turn where specifically permitted.
Where a broken line runs alongside a solid line, the rules depend on which side of the line you are on. Drivers on the broken-line side may cross to overtake if safe, while those on the solid-line side must not cross.
Special lines such as edge lines, painted islands, and turning lines also carry restrictions. Breaching these markings can result in fines and demerit points. Obeying them is crucial for safe driving in NSW.
Double yellow lines are another important marking drivers need to recognise. They are essentially treated the same as double continuous white lines. This means you must not cross them to overtake, change lanes, or perform a U-turn. The only exceptions are when it is necessary to enter or leave a driveway, side street, or property, or to safely avoid an obstruction. These lines are most often painted in areas where visibility is poor or traffic risks are higher, such as on winding roads, crests, and near intersections. Crossing double yellow lines illegally can attract penalties, including fines and demerit points, as they are designed to reduce the risk of serious head-on collisions. Car Accident Not Your Fault?
