Importance of Object Marking
Unlock Audio Lesson
Today, we're discussing the importance of marking objects within the carriageway. Can anyone tell me why visibility is crucial for these objects?
To prevent accidents, especially at night or in bad weather.
Exactly! Marking these objects helps alert drivers to potential hazards they might not see otherwise. What kind of objects are we specifically talking about?
Things like traffic islands and signal posts.
Correct! Now, can anyone recall the color patterns used for these markings?
Black and yellow alternating stripes!
Great memory! The stripes must also slope at a 45-degree angle to be effective. Let's summarize: marking helps visibility, specific colors are used, and the angle of stripes is important for safety.
Guidelines for Marking Obstructions
Unlock Audio Lesson
Moving on, what do we need to ensure when marking objects like traffic islands? Who remembers how many stripes we need?
At least five alternating black and yellow stripes!
Right! And what is the required width for these stripes?
They should be not less than 100 mm wide.
Excellent! Now, why do we use such specific measurements?
To ensure they’re clearly visible to drivers.
Exactly! Visibility is key for road safety. To wrap up this session, remember the importance of the number of stripes, their color, and their width.
Application of Marking Guidelines
Unlock Audio Lesson
Let's apply our knowledge! Imagine you're designing a new road and need to consider the marking requirements for obstructions. What would you include?
I'd make sure to include the five stripes and ensure they're sloping correctly.
Great! And what about the color?
They must be alternating black and yellow.
Perfect! In summary, when marking for road safety, we focus on the number of stripes, their colors, angle, and width. Always think about how a driver would perceive them.
Introduction & Overview
Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.
Quick Overview
Standard
The section details how physical obstructions in the carriageway, such as traffic islands and signal posts, should be marked using alternating black and yellow stripes. These markings provide visibility to road users, especially on obstructions that may pose hazards to traffic flow.
Detailed
Objects within the Carriageway
In this section, we explore the critical aspect of marking objects within the carriageway that may present hazards to vehicular traffic. These objects include physical obstructions like traffic islands, signal posts, and other structures. To enhance visibility and safety, these obstructions must be marked with no less than five alternating black and yellow stripes sloping at a 45-degree angle towards the side of the obstruction that traffic travels.
The stripes must be uniform, measuring not less than 100 mm wide, ensuring that they are clearly visible to approaching vehicles. This approach aims to alert drivers to potential hazards, thus contributing to a safer driving environment.

The obstructions within the carriageway be marked by not less than five alternate black and yellow stripes. The stripes should slope forward at an angle of 45° towards the side of the obstruction on which traffic passes.
Detailed Explanation
When there are obstacles in the middle of the road, they need to be clearly marked to prevent accidents. To do this, we use five stripes that alternate between black and yellow. These stripes have to be slanted forward at a 45-degree angle towards the side of the road where cars will be passing. This visibility helps drivers notice the obstruction from a distance and take necessary precautions.
Examples & Analogies
Think about how crossing guards wear bright colors to make themselves visible to children and drivers. Similarly, the black and yellow stripes serve as a visual warning to drivers of the obstacles ahead, much like a brightly colored warning sign or a flag.
Width of the Stripes

These stripes shall be uniform and not less than 100 mm wide to provide sufficient visibility.
Detailed Explanation
The stripes used to mark the obstructions are required to be at least 100 mm wide. This uniform width ensures that they are easily visible to drivers, even at a distance or in poor visibility conditions. Having a consistent and adequate width helps in maintaining clear guidance for upcoming traffic, ensuring safety.
Examples & Analogies
Imagine trying to see a narrow thread on a busy road compared to a wide ribbon. A wide ribbon is much more noticeable, just like the adequately wide stripes help drivers notice and react to obstacles in the roadway.
