Edge lines must be painted at least 150 mm from the edge of the pavement. Can anyone tell me why this distance is important?
So that cars don’t go off too far?
Yes! It provides a buffer zone. They can be colored either yellow or white. What do you think about the color choice?
I guess white might be better during the day, and yellow could be helpful at night?
Great observation! Different colors can enhance visibility in various conditions.

Quick Overview
Standard
Edge lines serve as important markers for the edges of rural roads lacking curbs, ensuring drivers stay within safe limits. They should be at least 150 mm from the pavement's edge and may be painted in yellow or white for visibility.
Detailed
Detailed Summary of Edge Lines
Edge lines play a crucial role in road safety by delineating the safe limits for drivers on rural roads that do not have curbs. These markings help prevent vehicles from veering off the road into potentially hazardous areas. The specifications for edge lines include that they should be painted at a minimum distance of 150 mm from the actual edge of the pavement. The colors used for edge lines can be yellow or white, which enhances visibility to drivers, especially in low-light conditions. These markings are designed to act as psychological barriers, providing drivers with a visual guideline for safe driving practice.

These indicate edges of rural roads which have no kerb to delineate the limits up to which the driver can safely venture.
Detailed Explanation
Edge lines are used to help drivers understand where the safe driving area ends. On rural roads that do not have a physical barrier like a kerb, these lines become crucial in guiding drivers and ensuring their safety. They serve as a visual indicator of the road limits, preventing vehicles from going off-road, which can lead to accidents.
Examples & Analogies
Imagine driving at night on a road without streetlights. If there's no kerb to show you where the road ends, it can be easy to drift off the side into a ditch. Edge lines are like the faint glow of a flashlight guiding you back to the safe path.
Distance from Pavement Edge

They should be at least 150 mm from the actual edge of the pavement.
Detailed Explanation
The distance of edge lines from the pavement is designed to give drivers a margin of safety. By keeping edge lines a minimum of 150 mm away from the actual edge, it reduces the likelihood of a vehicle accidentally crossing over the edge while still providing a clear signal of the boundary. This space allows for slight deviations that can occur due to steering difficulties or sudden maneuvers.
Examples & Analogies
Think of walking along a cliff's edge. If you have a rope 150 mm back from the edge, you can lean a little without falling off, giving you the confidence to move safely along. Edge lines function similarly for drivers on the road, offering them a buffer zone.

Chapter Content
They are painted in yellow or white.
Detailed Explanation
The color of the edge lines—either yellow or white—conveys important information to the driver. Yellow is often used to indicate warnings or caution, while white lines are commonly associated with guiding and indicating safe driving paths. This differentiation helps drivers quickly understand the significance of the markings and respond accordingly.
Examples & Analogies
Consider the color coding in a grocery store. Yellow signs often alert you to sales (like edge line warnings), while white signs generally indicate where to find products (like guiding your driving path). The colors help you navigate through the aisles, just as edge line colors help drivers navigate through rural roads.
