The M2 Edge Line is a crucial traffic sign that marks the outer boundary of the drivable roadway. It helps you accurately judge the road's edge and maintain your correct lateral position, which is especially important in poor visibility conditions like darkness, rain, or snow. This marking is vital for ensuring safety and preventing unintended departures from the carriageway, particularly on narrow rural roads or in curves. Always use it to stay properly positioned, not as an excuse to overtake or squeeze past other vehicles.

No, you should not treat the shoulder as an extension of the driving lane. The M2 Edge Line indicates where the drivable surface ends. Using the shoulder as a lane is prohibited and can be dangerous, as it may be uneven, soft, or occupied by pedestrians or cyclists.
In conditions like heavy rain, fog, snow, or darkness, the physical edge of the road can become very difficult to see. The M2 Edge Line provides a clear visual cue, making it easier to judge your vehicle's position relative to the road's boundary and preventing you from straying off the carriageway.
A common mistake is mistaking the edge line for an invitation to drive further to the right than necessary, or to use the shoulder to overtake. Learners might also cut corners too closely to the edge line when turning. The M2 sign is purely for guidance on road position, not for extra space.
While the M2 Edge Line itself doesn't set a speed limit, it often appears on roads where a lower speed is advisable due to narrowness, curves, or reduced visibility. Drivers should adjust their speed appropriately based on the road conditions indicated or suggested by the presence of the edge line.
