7 common road lines explained

Straight, broken, yellow, white, bumpy – road lines come in all different patterns, colours and textures. Each has its place, and some may even save your life. Here are just 7 road markings to familiarise yourself with.  

1. The continuous line

Also known as the solid white line, the continuous line gives a stern warning to motorists: stay in your lane. But there are some exceptions to the rule.   When you can cross: Is there a broken-down vehicle or a fallen tree on the road ahead? Avoiding an obstruction is just one situation when you’re permitted to cross a single line, if it’s safe. You can cross a single continuous line when entering or leaving a road, to enter a service road or emergency stopping lane, or to park in angle parking on the opposite side of the road provided a U-turn is not required. Lastly, if space allows, motorists can cross a continuous line to manoeuvre around a cyclist to provide the safe passing distance. Just make sure you have a clear view of the road ahead and try to keep as far left as possible. Driving over a continuous line is also legal when it’s paralleled by a broken line painted closest to the motorist.   When you can’t cross: Overtaking a vehicle moving at a snail’s pace isn’t reason enough to cross a continuous line. Missed a turn? Motorists are also prohibited from travelling over a solid line to make a U-turn. Sometimes a continuous line is accompanied by a second solid line, bringing a double whammy of consequences should you ever cross it. Put simply: a motorist should never cross double continuous lines unless manoeuvring around an obstruction or cyclist, and only if it can be done safely. In South Australia, motorists are fined $405, a $60 Victims of Crime Levy and receive 2 demerit points if they’re caught crossing a continuous line unlawfully. Cross a double continuous line and you’ll face the same fine, but incur 3 demerit points.

2. The broken line

Similar to the continuous line, the broken line separates sections of the road to ensure motorists stay in their lane. There is, however, a big difference between the two.   When you can cross: Provided it’s safe, and sufficient indication has been given to other road users, motorists can cross broken lines at any time after they have given way to all vehicles in the lane they wish to enter.   When you can’t cross: If a broken line is paralleled by a continuous line closest to the motorist, you mustn’t cross it. Ignore that rule and you could be fined $405, a $60 Victims of Crime Levy and receive 2 demerit points.
