The Double Central Line marking (1006.1) is a crucial part of road organisation, guiding your vehicle's position and traffic flow directly on the carriageway. It's as legally binding as an upright sign and dictates where you can and cannot cross or use the road space. Always read road markings early, especially in varying weather conditions or when they may be worn, and adjust your position smoothly to comply with the traffic arrangement.
Understanding the Double Central Line (1006.1) is crucial for navigating Icelandic roads safely; it strictly defines legal restrictions on overtaking, crossing, and positioning. Mastering this road sign interpretation is vital for your theory test revision and ensures correct decision-making in all traffic scenarios.
Double Central Line is a painted or surface-applied marking used to organise movement on the road itself. Road markings guide positioning, separate opposing flows, indicate priorities, reserve space for certain users, and show where stopping, crossing, or turning is allowed or restricted. The safest approach is to read the marking early and adjust lane position before reaching it, especially where overtaking, crossing, or lane choice is affected. In winter or poor maintenance conditions, markings may be harder to see, but where visible they remain an important part of the legal traffic arrangement.
This road marking controls or guides double central line directly on the carriageway. It must be read just as seriously as an upright sign because it tells you how to position the vehicle, where you may cross, and which part of the road is reserved or restricted.

The Double Central Line marking (1006.1) is painted onto the road surface to guide traffic. It separates opposing flows of traffic and indicates where crossing or overtaking is prohibited. It's essential for maintaining orderly movement and preventing collisions, functioning just like an official traffic sign.
You must follow the guidance of the Double Central Line marking. This means keeping to your side of the lines and not crossing them if they indicate a prohibition on crossing or entering an area. Early observation and smooth adjustment of your vehicle's position are key to obeying these markings safely.
Generally, you should not cross a Double Central Line marking, especially if it's solid or clearly indicates a prohibition. If the marking is broken or designed to facilitate turns or lane changes at specific points, you may cross as indicated, but always prioritise safety and clear visibility.
Road markings like the Double Central Line (1006.1) remain legally important even if obscured by snow, dirt, or wear.

Exercise extra caution and observation, and if the marking's intent is unclear, drive defensively, assuming restrictions are in place.
